Build a Copper Network at Home

Broadband is becoming more and more important to our daily life. The Fiber to the Home (FTTH) is being widely deployed. Broadband provided by fiber optic cables is very common. However, most of our home devices are still having electrical interfaces like RJ45 interfaces. In addition, the copper network cable and technologies are keeping developing to satisfy the requirements of high data rate broadband. Thus, many people still have confidence in copper based network and would like to deploy a copper based network at home which is more cost-effective and easier to manage.

Factors to Consider Before Copper Home Network Deployment

To build a copper network at home is easier than that of a fiber optic based home network. But there are still a lot of things need to be considered. Before deploy the copper home network, you should firstly understand what you want from this copper home network. Of course, easier access to broadband and WiFi at everywhere are the most basic requirements. You should also decide the port number and expectation of the network performance, which will directly the decide product selection or cost of your network.

Three Steps to Build A Copper Home Network

There are mainly three steps to build a copper home network which will be introduced in the following part of this post.

distribution cable
Step One: Introduce Service Provider Distribution Cable to Your Home

Now most of the broadband service provider will install a distribution point near or inside a building. As shown in the above picture, copper network cables or fiber optic cables are deployed inside a building to bring services to every houses inside this building. For some old buildings, the cables between the end users and distribution point are still copper based. For many new buildings, these cables are usually fiber optic based. Just add an ONU (Optical Network Unit), you can change these optical signals into electrical signals and distribute signals to different ports and home devices. If your apartment is a small one, you can just use one ONU or router in the whole home network.

There are a variety of ONUs and routers which can support WiFi and satisfy various port requirements. For example, the following picture shows the application of a typical ONU (4FE+2POTS+WiFi) that can meet the requirement of most apartments. This ONU has a SC optical interface to be connected with the service provider’s entry fiber optic cable. Except two voice ports and four LAN ports, this ONU provides WiFi function.

4FE+2POTS+WiFi
Step Two: Wiring the Whole House

Wiring the whole house is very important for a home network with good broadband access. It is known that most home devices have better performance via a wired connection compared with being connected to WiFi. So during this process, you should device the port number you should leave in your house and how many devices should be connected to the network. Now there are a variety of home devices can be connected to a home network for better and smarter performance, which is also called smart home. Devices like air condition, light control and televisions can all be connected to the home network. Thus, copper network cable for signal transmission should have good and reliable performance. Cat6 and Cat7, two types of high performance Category copper cable, which can meet the requirement for both now and future, are strongly recommended.

The above picture shows the copper cabling for an apartment. The bedroom, living room, office and dining room of this house is all connected to broadband via copper network cable. In addition, each room is connected to voice cable ensuring that the house owner would not miss phone calls in most part of the house.

Step Three: Terminate Copper Cables and Connect Them to Home Devices

For the sake of security and reliability, the copper network cables should be terminated at wall plate ports. And a length of RJ45 copper network patch cable should be used to connect the port with target device as shown in the following picture.

PLC Splitter Selection Guide

PLC splitter is a simple passive component which plays an important role in the applications of technologies like GPON, EPON and BPON. It allows a strand of fiber optic signal being equivalently splitted into several strands of optical signal, which can support a single network interface to be shared by many subscribers. When selecting it, split ratios should always be considered. However, with the network cabling environment becoming increasingly complex, various PLC splitters with different package form factors are being invented. Now the package form factor of it is also a key factor to be considered. This post will introduce the most commonly used PLC splitters in different package form factors for your reference during selection.

Bare Fiber PLC Splitter

Bare fiber PLC splitter is commonly used in FTTx projects. It leaves bare fiber on all its ends. Thus, they can be spliced by network engineer freely according to the applications. Meanwhile, it requires the least space during cabling. They can be installed in fiber optic splicing closure easily to provide FTTH signal distribution.

Blockless PLC Splitter

A blockless PLC splitter looks like a bare fiber splitter. The main differences are that the blockless one is usually terminated with fiber optic connectors and it uses a compact stainless tube package. It is also common that many bare fiber PLC splitters also use stainless tube package for the split chip.

Fanout PLC Splitter

Fanout PLC splitter generally uses 0.9mm buffer fiber, added with a length of ribbon fiber terminated with fanout kit behind the PLC split chip. The splitter ratios of it also come in various types. The following picture shows a 1:8 fanout version which is terminated with SC/APC connectors.

ABS PLC Splitter

ABS PLC splitter uses ABS plastic box to holding the splitter chip. The inbound fibers and distribution fibers are arranged on the same plate of this ABS box, which can provide easier and more flexible cabling. Except providing reliable protection, it can also be installed in a variety of boxes or enclosures. It is very commonly to install a it in a standard 19-inch rack unit.

ABS PLC splitter

LGX Box PLC Splitter

LGX Box PLC splitter looks like an MTP LGX cassette. It houses the whole splitter inside a metal box and leave fiber optic adapters for both inbound fibers and distribution fibers on its front panel. The LGX splitter can be used stand alone or be installed in the standard rack unit or fiber enclosures for better cabling.

LGX PLC splitter

Mini Plug-in PLC Splitter

Mini plug-in PLC splitter is now widely used in FTTx project, especially at the distribution points near the end users of the FTTx networks. It provides fast installation and low space requirement helping to alert the deployment of FTTs projects. Fiber pigtails for input and output can be directly connected with this passive component easily.

How to Build 10G CWDM Network

As a passive technology, CWDM allows for any protocol to be transported over fiber optic link at specific wavelengths. CWDM technology is a cost-effective and simple method to increase the capacities of fiber optic network, by using different wavelengths to carry different signals over a single optical fiber. The wide deployment of CWDM network is greatly driven by its affordable cost.

What Is Need for A 10G CWDM Network?

The deployment of a 10G CWDM network is relaying on the exiting fiber optic network. Adding some components on the existing network can largely increase its capacity for data transmission. Here will introduce the key component and an important step during 10G CWDM network deployment.

CWDM Mux/Demux
A Key Component—CWDM Mux/Demux

A key component should be deployed is CWDM Mux/Demux, which combines different wavelength signals from different optical fibers into a single optical fiber, or separates different wavelength signals coming from a single optical fiber to separate optical fibers. The Channel number of a CWDM Mux/Demux is an important factor to divide this device. Standards have identified 18 CWDM Channels. Most of the CWDM Mux/Demux are provided with Channel number range from 2 to 16. However, FS.COM provides a 18-Channel CWDM Mux/Demux which can increase capacity of CWDM network to the most. CWDM Mux/Demuxs also come into a variety of package form factors. The most commonly used are LGX design, rack design and pigtail design.

CWDM Cabling
An Important Step—Connecting CWDM Mux/Demux With 10G Switch

Connecting CWDM Mux/Demux with a 10G switch, is the most important step to build a 10G CWDM network. In simple, to add more devices on the fiber optic network by CWDM technology is to connect the CWDM Mux/Demux with the 10G switches which are linked to the end users. To link CWDM Mux/Demux with the switches, fiber patch cable and 10G CWDM SFP+ transceiver are needed. 10G CWDM SFP+ transceiver should be installed on the switch SFP+ port (some switches use XFP port, then 10G CWDM XFP transceiver is required). Then a length of fiber patch cable should be used to link the transceiver and CWDM Mux/Demux.

CWDM SFP+

How to Select to Right 10G CWDM SFP+ Transceivers?

Choose the Right Working Wavelength: To ensure the right connection, the specific wavelength port should be connected to the same wavelength CWDM SFP+ transceivers. For example, the port on the CWDM Mux/Demux marked with 1270 nm, should be connected to a CWDM SFP+ transceiver that working over wavelength of 1270 nm. As there are 18 different CWDM wavelengths, 10G CWDM SFP+ transceivers that are provided in the market also can 18 different versions for these wavelengths.

Choose the Compatible CWDM SFP+: It is common sense that the fiber optic transceiver should be compatible with the switch which it works on. For instance, if you are using a Cisco switch, the fiber optic transceivers that you used with this switch should be original Cisco transceivers or Cisco compatible transceivers which are provided by third party vendors. The latter is usually the choice of many companies, this is because third party transceivers are usually more cheap than the original brand transceivers. Fiber optic transceivers provided by third party vendor like FS.COM are all fully tested on original brand switch to ensure their compatibility and quality. What’s more, most of FS.COM fiber optic transceivers support same day shipping. Select the right SFP do not only cut your cost and time, but also provide high network performance.

Choose the Transmission Distance According to Your Needs: CWDM network is usually deployed for long distance transmission. Thus the 10G CWDM SFP+ transceiver that are provided in the market usually support transmission distance longer than 20 km, some can support link length up to 80 km or more. You can select the 10G CWDM SFP+ according to your requirements.

Here list the generic whole band 10G CWDM SFP+ fiber optic transceivers that support link length of 20km, 40km and 60km. If you need the brand compatible CWDM SFP+, kindly contact sales@fs.com or visit FS.COM for more details.

Cable Tie Is Not as Easy as You Think

When think of cable ties, most people would firstly thought of a bunch of self-locking throwaway plastic strips. One might think a cable tie is just a cable tie. There are many uses for cable ties. And there are also a wide variety of cable ties which are designed for different applications. The plastic self-locking cable ties are the most commonly used ones. However, even these simple plastic loops come into various types according to their color, length, width, and serrations. Proper cable ties do not only provide long-life and dependable services but also better cable management, especially in data centers and server rooms which are the worlds of various cables. To choose the right cable tie for your applications, this post would like to offer some suggestions when making your decisions.

Locking Design of Cable Tie

Self Locking Cable Tie: The most important thing of a cable tie is its locking technology. With a good locking design, cable tie can provide firm locking for the cables. The most commonly used cable tie is also called zip tie, which is one-piece design with a lot of serration on the cable tie to lock the cables firmly. The following picture shows the structure of this cable tie. This design allows the cable tie to perform to the published minimum tensile strength.

Reusable Self-Locking Cable Tie: The zip tie is easy to use and affordable. However, this type of cable tie cannot be reused, cause once the cable tie is locked it would be really hard to unlock or release it. You have to cut them down if you don’t need them. To improve this design, a little latch is added on the tongue of the cable tie, which makes the cable ties reusable. As shown in the following picture, the reusable self-locking cable tie can be easily released by pressing the latch on the tongue, which can perfectly ignore the affection of the serrations on the cable tie.

Magic Velcro Cable Tie: This type of cable tie is also reusable. The hooks and hairs on the cable tie can provide firm locking for the cables (shown in the following pictures). And it can make cable management safer and more convenient. It is also widely used in household applications to organize wires. This Velcro cable tie is usually sold in rolls.

Identification Cable Tie: the above mention cable ties are all available in different colors. Color is a useful feature for identification. Thus, customers can use cable tie in different colors for identification. However, it happens that the color is not enough for cable identification if there are too many cables or too much information. Then, an improved cable tie with a marker or label attached on the cable tie is offered (shown in the following picture).

Materials of Cable Tie

The function and performance are also largely depended on the materials of the cable ties. The above mentioned cable type are the most commonly used ones, which are usually made of plastic, Nylon and Velcro. However, for some harsh environment, elements like temperature and strength should be considered during cable tie selection. There is a type of cable tie which is made of stainless steel, usually known as heavy duty stainless steel cable tie(as shown in the following picture). It is commonly used in outdoor applications.stainless steel cable tie

Other Factors to Consider During Cable Tie Selection

The length of cable ties available in market ranges from 4 to 52 inches. The cable tie length should be longer than the diameter of the cable bundle. It cannot be too long or too short. The proper width of a cable tie will also help a lot. Both the length and width of the cable ties should be depended on the applications.

How to Choose the Right Type of Optical Transceiver

Choosing the right optical transceiver is not easy. You can approach the selection process by reviewing the device as a single entity or you can explore the fiber cable separately. Either way, you need to be aware of what’s needed for your application to work optimally. If you know what you need to edge out the competition, you’ll be in a better position when you’re speaking with representatives about the fiber optic cable. Here’s what you should consider:

Which Fiber Mode That’s Required
There are two basic types of fiber: multimode fiber and single-mode fiber. Multimode fiber will allow each signal to travel on more than one pathway at one time, which is best designed for short transmission distances, and is suited for use in LAN systems and video surveillance. Single-mode fiber is best designed for longer transmission distances, which is used in applications that need bandwidth that will travel over long distances.

Determine if You’ll Need Full-Duplex or Half-Duplex
Some chips will only use full-duplex configuration. Selecting switches, HUBs, or transceivers with half-duplex mode may cause loss and conflict. Only choose full-duplex unless you think that your application can support half-duplex. Nowadays, Ethernet interfaces on the switch operate at 10, 100, or 1000 Mbps, or 10,000 Mbps and in either full- or half-duplex mode.

Consider Whether You’ll Need a Safety Device to Prevent Packet Loss
Some vendors may just need to reduce costs and loss. Thus, they have to choose an optical transceiver with maximum safety features and loss prevention.

Consider Whether the Transceivers Have Temperature Adaptability
Optical transceivers shouldn’t run hot. Optical transceivers may fail prematurely at high temperatures. That is why it’s important to know how well an optical transceivers can adapt to heat if it will be in high temperatures.

Determine if You’ll Need Copper or Optical Fiber
Take an example of Gigabit Ethernet SFP module, 1000BASE-T (e.g. GLC-T) SFP module operates on standard Category 5 wiring and has a RJ-45 connector. 1000BASE-SX SFP transceiver operates on ordinary multi-mode fiber optic link spans of up to 550 m in length. 1000BASE-LX/LH SFP operates on single-mode fiber (SMF) for a maximum length of 10km. 1000BASE-ZX SFP using an extended wavelength operates on single-mode optical fiber for up to 100km.

Consider the Construction of the Fiber You’ll Need
There are some basic types of internal construction, but you have to choose the one that will work best for your application. One of the most popular types is the distribution or tight pack. The second type of construction is the breakout or fanout design. This design gives each buffered fiber its own individual jacket and is a more durable design.

optical transceiver typeThe zip cord or assembly is another type of internal construction that is offered to the designers. This is one of the preferred internal construction options. In this construction, one or two buffered fibers in individual jackets should be considered. Single fiber cable is recommended for patching.

The last factor you should consider is the level of flame resistance. Remember that there are three different grades available: general, special, and high. The level of flame resistance can be measured through a variety of tests including those determining smoke density values and flame propagation.

Choosing the Right Fiber Transceiver Type is Not Easy
Choosing the right fiber transceiver type is not easy. There are lots of elements to be considered. These are typically considered on a case-by-case basis. Consider all of the factors mentioned such as the internal construction, fiber mode, fiber cable jackets, and the level of flame resistance.
