The Reason of Choosing 10GbE RJ45 Switch

10GbE means the speed will be 10 times faster than a normal Gigabit network. Visually, there’s no difference. But if you need to copy large files, a 10GbE switch is necessary. However, why we use the RJ45 type, not the fiber one? Because RJ45 ports can be connected by the copper cables which are something we all are used to. And SFP switch is popular in data centers, which needs to be connected by the expensive fiber cables. RJ45 switch is better since it can be backward compatible with people’s older computers. This is a perfect solution for home use or SMB, since these users would not like to cost too much to buy fibers or new optical equipment. Therefore, a 10GBASE-T switch is their first option.

Understanding Power Consumption of PoE Ethernet Switch

As PoE changes to meet today’s increasing application requirements like IP cameras or WiFi access points, it’s widely used for enterprises networks. Using a PoE or PoE+ switch, technicians can simplify the cabling installation because the PoE technology can support power and data transmission over the same cables. When choosing a PoE Ethernet switch, we always care about the ports and power consumption most. This article will introduce the power consumption of PoE Ethernet switch and take two PoE Ethernet switches as examples to explain power consumption.

What Is Power Consumption of PoE Ethernet Switch?

At present, PoE power consumption follows two standards, IEEE 802.3af and 802.3at. The original IEEE 802.3af rules that power consumption on each port of a PoE network switch can be up to 15.4W. The updated IEEE 802.3at standard also named PoE+, which is backward-compatible with IEEE 802.3af, provides up to 25.5W of power on each port. However, because the power dissipate exists in cables, the minimum output power assured on each port for PoE switch is 12.95W, and 25.5W for PoE+ switch.

power consumption standard

Figure 1: IEEE 802.3af and IEEE 802.3at standards.

The key to successful PoE installation is to ensure that the selected power over Ethernet switch provides the necessary watts of PoE required for each device, and the total power consumption also must be guaranteed for powering all devices. Simply put, the total power consumption of all the connected devices must be controlled in the range of the PoE switch max power consumption.

How Many Devices Can I Connect to My PoE Ethernet Switches?

Power consumption of 150W and 400W are the most popular choices on the market. The following are two switches from FS, 8 port PoE switch and 24 port PoE switch, and we’ll use them to further explain the question how many devices can we connect to my PoE Ethernet switches.

PoE Ethernet switches applications

Figure 2: How many devices can be connected to a PoE switch?

How Many Devices Can the 8 Port PoE Switch Connect?

FS S1150-8T2F switch is a managed PoE+ switch. It has 8 10/100/1000Base-T RJ45 ports, and 2 Gigabit SFP slots. Its PoE standard complies with IEEE802.3af/at. And designed with a max power consumption of 150W, each port can support up to 30W power. This means the switch provides the availability of PoE on all 8 RJ45 ports, and each port can potentially power devices that are connected. From the above, we know the standard PoE can supply 15.4W power for each port, and 30W for PoE+. Therefore, this switch can simultaneously connect 8(15.4W×8=123.2W<150W) devices that use IEEE 802.3af standard, and only 5(30W×5=150W) devices that use IEEE 802.3at standard. For example, if a typical outdoor IP camera needs a PoE power of 20W, the connection of 7 typical IP cameras will require 140W of PoE power (7×20W), which is well within the power consumption of this network switch.

How Many Devices Can the 24 Port PoE Switch Connect?

FS S1400-24T4F managed PoE+ switch is designed with 24 Gigabit PoE+ ports, 1 console port and 4 Gigabit SFP ports. This switch complies with IEEE 802.3af/at with a max power consumption of 400W and 30W for each port. Through a calculation, we know the 24 port switch can connect 24(15.4W×24=369.6W<400W) devices with PoE standard at the same time, and support 13(30W×13=390W<400W) devices with PoE+ standard. And as for the same outdoor IP camera with a power requirement of 20W, the 24 port switch can support 20(20×20W=400W) cameras.

Conclusion

Knowing the power consumption of PoE Ethernet switches is very important. If you want to connect multiple devices to a PoE switch, you need to calculate the total power consumption that all the devices require, and make sure you PoE switch can provide the needed current.

FS Fiber Optic Cable Types

To date, fiber optic cables have brought high speed network services to companies, campuses and homes. And we have discussed fiber optic cables a lot in the past, such as Introduction of Fiber Optic Cable. However, the truth is we have just scratched the surface of this complicated system. Different fiber optic cable types are versatile in the function and installation. Today, we’ll introduce FS fiber optic cable types in order to further understand the optic cables.

Why Fibers?

Fibers are truly one of the greatest inventions of our world. They are slim cables that have thousands of optic fibers within the plastic, outer jacket. The optic fibers are incredibly hair-thin strands of glass that transmit data by light, which is quite different from the copper cables or RJ45 cables. Basically, compared with the copper cables, fiber cables are much more efficient and secure for network applications. They can deliver more data with a greater degree of fidelity over greater distances. In addition, because fiber cables are made of glasses, they are immune to any type of electrical interference. Therefore, these cables could be put in direct contact with soil or in close proximity to chemicals without concern.

FS Fiber Optic Cable Types

To make a clear product catalog, FS has classified the fiber cables by different applications. Therefore, people can select the cables more easily according to their various needs.

MTP/MPO Fiber Cable

MTP/MPO fiber cables consist of MTP/MPO connectors and fiber cables. Each cable can bring 8, 12 or 24 fibers together in a single MTP/MPO interface. And other connectors like SC or LC are also could be found in some MTP/MPO cables. MTP/MPO cables are designed for 40 or 100G applications in data centers for ultra-high density cabling. FS MTP/MPO cables have low insertion loss, and help you reach direct connection for 40G connectivity. As the figure shows, MTP/MPO cable is usually used for connecting optic transceivers, MTP cassettes and fiber adapter panels and so on.

Fiber Patch Cables

Usually, fiber patch cables are terminated with fiber optic connectors such as LC, SC, ST and so on at each end of the cables. Through these connectors, optical cables can be connected to network switches, patch panels or other networking devices. Based on fiber cable mode, fiber patch cables are divided into single mode fiber like OS2, and multimode fiber such as OM3 and OM4. All FS fiber patch cables are made of PVC jacket material with low insertion loss and attenuation at different distances. They play important roles for indoor uses like server rooms. Commonly, fiber patch cables are used to connect transceiver modules. Note that, fiber cables with different connectors must be connected with the transceivers that have the corresponding interfaces. For example, the following cable is a LC to LC single mode cable. Therefore, the transceivers here must have LC interfaces.

Ultra HD Fiber Cables

In FS ultra HD fiber cables catalog, there are ultra low loss LC SMF/MMF, uniboot LC cables, BIF fiber cables and customized LC+ cables. Compared with traditional fiber cables, ultra HD fiber cables use a compact design with a flat clip model and a slimmer wire body, which saves about 50% of cabling space. This is extremely suitable for high density data centers.

How to Choose a Gigabit Network Switch?

Gigabit network switch is the most commonly used equipment in data centers. Before choosing the best network switch for the current or future network, people can type “Ethernet switch” into the online shopping site or search engine, they may find a ton of listings for switches of all kinds and price levels. It’s not an easy job to find one. Then how to choose a Gigabit network switch in order to avoid buying the wrong device or overspending needlessly?

Types of Gigabit Network Switch

Gigabit Ethernet switch can be divided into unmanaged, managed and PoE categories.

Unmanaged switches use the plug-and-play design that means they only allow Ethernet devices to communicate with one another. They are shipped with fixed configuration and don’t allow any changes to this configuration. This type of network switch is normally found in home networks or small business.

Managed switches offer all the features of unmanaged switches and are capable of configuring, managing and monitoring one’s LAN. Users have greater control over how data travels over the network and decide which one has access to it.

PoE switches support electrical power and data transmission over one network cable, which will greatly simplify the cabling process. Using a PoE switch, people don’t need to worry about power outlet when deploying network devices.

Features of Gigabit Network Switch

With a network switch, users can have different networked devices on their desks as well as bandwidth-intensive applications that require high rates of data transmission and no tolerance for congestion. These switches are the basics of modern wired network. They can not only provide the connections to PCs and other devices in a wide variety of fields, but also support the cloud storage of servers. With new trends like SDN and the IoT transforming the industry, people have to get the features that they need from the switches, so that they would know which switch is the one that they need.

How to Choose a Gigabit Network Switch?

Here are the most important facts you should consider when choosing a Gigabit network switch.

  • Choose the role of the switch. If you are just looking for a device to extend your wired network at home, one unmanaged switch is suitable. And an 8 port Ethernet switch or 12 port switch is enough for home network. If you want to find a switch for a large network, you may buy one or more managed switches acting as core switches. 24 port and 48 port PoE managed switches are the right choice.
  • Choose the forwarding rate of the switch. Gigabit switches have different processing rate. Processing and forwarding data rates are very important. The processing rate becomes lower, the forwarding rate will be slower. This may make the switch unable to accommodate full wire-speed communication across all the ports. So people should figure out what forwarding rate they need before buying a Gigabit switch.

Conclusion

From the above, we know how to choose a Gigabit network switch. If you have decided to buy a network switch, welcome to visit FS.COM. FS has a good selection of 10Gb switch, 40G or even 100G switch and PoE switch for home and office users.
