What are MPO and MTP connectors?

MPO MTP cables are offered for various applications for all networking and device needs like 100 Gig modules. They use a high-density multi-fiber connector (MPO connector and MTP connector) system built around precision molded MT ferrule. So what are MPO and MTP connectors?

What is an MT ferrule?
MT stands for Mechanical Transfer. The MT Ferrule is a multi-fiber ferrule in which fiber alignment is dependent on the eccentricity and pitch of the fiber and alignment pin holes. The alignment is dictated by the alignment pins during mating.

The critical elements for fiber alignment are:

1. The ability to hold extreme tolerances for precision during the molding process

2. The shape, tolerances and material composition of the alignment pins

What is a MPO connector?

MPO is the industry acronym for “Multi-fiber Push On.” The MPO-style connectors are most commonly defined by two different documents:

1. IEC-61754-7 is the commonly sited standard for MPO connectors internationally

2. EIA/TIA-604-5, also known as FOCIS 5, is the most common standard sited for in the US

What is a MTP connector?

The MTP connector is a high performance MPO connector with multiple engineered product enhancements to improve optical and mechanical performance when compared to generic MPO connectors. It is in complete compliance with all MPO connector standards including the EIA/TIA-604-5 FOCIS 5 and the IEC-61754-7. It is inter-matable with all generic MPO-style connectors that are compliant to these industry standards. Generic MPO connectors are limited in performance and are not able to offer the high performance levels of the US Conec MTP connector.

Is the MTP connector an MPO connector?

Yes. The MTP connector is a high performance MPO connector engineered for better mechanical and optical performance.

What makes the MTP connector superior to generic MPO connectors?

The MTP connector has features and benefits that are not available on generic MPO connectors. Some of the key distinctions include:

1. The MTP connector housing is removable. This feature allows the customer to:

A. Re-work and re-polish the MT ferrule

B. Change the gender after assembly or even in the field

C. Scan the ferrule interferometrically after assembly

2. The MTP connector offers ferrule float to improve mechanical performance. This allows two mated ferruled to maintain physical contact while under an applied load.

3. The MTP connector uses tightly held tolerance stainless steel guide pin tips with an elliptical shape. The elliptical shaped guide pin tips improves guidance and reduces guide hole wear.

4. The MTP connector has a metal pin clamp with features for centering the push spring. This feature:

A. Eliminates lost pins

B. Centers spring force

C. Eliminates fiber damage from spring

5. The MTP connector spring design maximizes ribbon clearance for twelve fiber and multifiber ribbon applications to prevent fiber damage.

6. The MTP connector is offered with four standard variations of strain relief boots to meet a wide array of applications.

A. Round, Loose Fiber Cable Constructions

B. Oval Jacketed Cable

C. Bare Ribbon Fiber

D. Short boot which reduces the footprint by 45%. Ideal for use in space limited applications.

ADSS (All Dielectric Self Supporting)

ADSS cable is loose tube stranded. Fibers, 250µm, are positioned into a loose tube made of high modulus plastics. The tubes are filled with a water-resistant filling compound. The tubes (and fillers) are stranded around a FRP (Fiber Reinforced Plastic) as a non-metallic central strength member into a compact and circular cable core. After the cable core is filled with filling compound, it is covered with thin PE (polyethylene) inner sheath. After stranded layer of aramid yarns are applied over the inner sheath as strength member, the cable is completed with PE or AT (anti-tracking) outer sheath.

ADSS Aerial Cable is designed to be freely suspended between upright supports such as poles, posts and masts. The construction is waterproof in longitudinal direction thanks to the use of jelly-filled bundle conductors and swelling tape. The outer jacket is UV-resistant and at the same time provides protection against environmental influences such as snow, ice, sun isolation and wind. The loose tube design provides stable performance over a wide temperature range and is compatible with any telecommunications-grade optical fibre.  ADSS is available in various span lengths and wind loads.

ADSS cable can be installed using live-line methods on an energized transmission line. Fiber cables are generally supported on the lower cross-arms of the tower, which provides good clearance to the ground. When the fibers are installed in the middle of a tower, the fiber cable is unlikely to hit energized conductors. Lower weights and forces are used for installation, compared with metallic cables, so lighter equipment can be used.
Installation technique is similar to installing overhead conductors, with care taken to prevent excessively tight bending of the cable, and adjustment of the sag of individual spans as for metallic cables.

4 parts of fiber optic cables

In this artical you will have a clearly  knowing about fiber optic cale composition

1 Fiber optic cable core:

A fiber optic’s center is made of glass, and this tube carries the cable’s light signals. Depending on the type of fiber optic cable (single mode or multi mode), the core varies in size. Single mode fibers consist of a tiny glass core that typically has a diameter between 8.3 and 10 microns. This type of cable is usually installed for transferring high speed data over long distances. For multi mode fibers, the core is larger. Their core size ranges from 5 to 7 times larger than single mode cores. With a diameter ranging between 50 to 62.5 microns, multi mode fiber optic cables are perfect for high data applications. Multi mode cables are typically used over shorter distances than single mode fiber optic cables.

2 Fiber optic cable cladding layer –Also constructed of glass, this “core cover” is used to keep the light in the core. When transmitting data (especially over long distances), light rays can reflect off each other and travel in different directions. The cladding keeps those signals straight.

3 Fiber optic cable Buffer – Also called the buffer coating, this sleeve protects the core and cladding from foreign material (FM) such as outside light, moisture, dirt and other substances. More often than not, the buffer is made of plastic.

4 Fiber optic cable Jacket – The fiber optic’s cable exterior is typically made of tough, durable polyurethane. Its job is to protect the overall integrity of the fiber optic cable. The jacket is the first line of defense in a fiber optic cable. Routing cables can put stresses on a fiber optic cable (kinks, knots, etc.) and a jacket sometimes contains an extra layer to avoid these potential hazards.

Fiber Optic Cables Are The First Option For Data Transmission

Fiber Optical Cable has brought a revolution to the data transmission system. As the earlier Electrical Wire System was difficult to manage and was sometimes also hazardous to life. With the emergence of Fiber Optical Cable, data transmission is no more an irksome job. It is now simplified, providing much more convenient than ever imagined.

Following Are The Reasons For Choosing Optical Cables For Network Cabling:

Safe To Use: Fiber Cable is far better than copper cable from the safety point of view. Copper and Aluminum Wire are good conductors of electricity and carry electric current. But when their outer insulated coating gets damaged, one can experience electric shock that can be dangerous to life. In this regard, Fiber Cables are safer to use because they do not transmit current but rather light waves.

Withstand Rough Conditions: Fiber Cable is capable of resisting tough conditions that co-axial or any other such cable cannot do. The reason is that other cables are usually made up of one or the other metal and are prone to corrosion, while Fiber Cable is covered with protective plastic coating with glass inside and transmits light impulses in spite of electric current, which make it resistant towards corrosion.

Long Distance Data Transmission: There cannot be any comparison in terms of data carrying capacity of Fiber Optical Cable and Copper Cable. Fiber Cable can transmit signals 50 times longer than Copper Cable.

Moreover, signal loss rate of Fiber Optical Wire is also very less, and thus does not need any kind of reminder in transmitting the signals at same pace. Fiber Cable has higher bandwidth that is amount of data communication resources available or consumed – this is the reason how Fiber Cable can transmit data at longer distances.

Easy Installation: Ethernet Cable is long and thin with intact cables inside. It is also light in weight which makes its installation at almost every place easier as compared to other wires.

No Electrical Interference: Fiber Optical Cable neither carries electric current nor need earthing. Therefore, it does not get affected by the electrical interferences. Fiber Cable is immune to moisture and lighting, which makes it ideal to be fitted inside the soil or an area where there is high Electromagnetic Interference (EMI).

Durable and Long Lasting: Fiber Optical Cable is durable and lasts longer than any other cable such as Co-Axial Cable, Copper Cable, etc. It is perfect for network cabling.

Data Security: Extra security can be provided with Fiber Optical Cable as it can be tapped easily and data transmitted through it remains secure, while in case of the Copper Cable there is no surety of data security and any loss of data cannot be obtained back.

There are various types of optical fiber cables available on the market, including 250um Bare Fiber, 900um Tight Buffer Fiber, Large Core Glass Fiber, Simplex Fiber Optic Cable, Duplex Fiber Cable, OM4 OM3 10G Fiber Cable, Indoor Distribution Cable, Indoor & Outdoor Cable, Outdoor Loose Tube Cable, Fiber Breakout Cable, Ribbon Fiber Cable, LSZH Fiber Optic Cable, Armored Fiber Optic Cable, FTTH Fiber Optic Cable, Figure 8 Aerial Cable, Plastic Optical Fiber, Polarization Maintaining Fiber & Special Fiber, etc. They are used for different applications, one must do a thorough research before buying fiber cables for network cabling.

Simplex And Duplex Fiber Optic Cables

It is important to understand the different varieties of core characteristics that are available within the fiber optic cabling itself, as each of these different characteristics will have different effects on your ability to transmit information reliably. Have a look at the most common fiber optics cores used in the industry nowadays.

Simplex Fiber Optic Cable

Simplex means this cable is with only one thread of fiber optic glass inside the single core. And simplex cables are with one single outer jacket. Simplex fiber optic cable is used in applications that only require one-way data transfer. For instance, an interstate trucking scale that sends the weight of the truck to a monitoring station or an oil line monitor that sends data about oil flow to a central location. There are singlemode and Simplex Fiber Cable available. Single-mode simplex fiber optic cable is a great option for anyone setting up a cable network that will require data to travel in one direction over long distances. Since this type of cable only carries one ray of light at a time, it’s better for long-distance transmissions. Single-mode fiber itself has a high-carrying capacity, is very reliable, and has lower power consumption than other options.

Analog to digital data readouts, interstate highway sensor relays, and automated speed and boundary sensors (for sports applications) are all great uses of Simplex fiber optic cable. This form of fiber cable can be cheaper than Duplex cables, because less material is involved. Simplex cable is compatible with any HDMI extender.

Duplex Fiber Optic Cables

Duplex fiber cable can be regarded as two simplex cables, either single mode or multimode, having their jackets conjoined by a strip of jacket material, usually in a zipcord (side-by-side) style. Use duplex multimode or singlemode fiber optic cable for applications that require simultaneous, bi-directional data transfer(One fiber transmits data one direction; the other fiber transmits data in the opposite direction). Duplex fiber is available in singlemode and multimode.

Duplex Fiber Optic Cable and Singlemode duplex cable alike are used for two-way data transfers. Larger workstations, switches, servers, and major networking hardware tends to require duplex fiber optic cable. Duplex cables can be more expensive than Simplex cables, and are compatible with any HDMI extender.

Simplex and duplex are with various cable structure types; they are different from single mode and multi mode which are related to fiber optic glass types.

Multi Fiber Cables

Both multi fiber cables and simplex cables are with a single outer jacket, but simplex only has one thread fiber glass inside the core, while multi fiber has many threads of fiber optic glass inside the core. For example, an 8-core multi fiber cable. There are ribbon type and bundle type multi fiber cables.

Single-mode fiber cables and multi-mode fiber cables are similar in many ways, with the main difference being that the glass center of single-mode cables is significantly smaller, at about 10 microns in diameter. The smaller size is what allows these cables to transmit data up to 40 miles with a bandwidth of 1Gbs.

Only need a simplex fiber cable if data will be traveling in one direction, such as with a security camera or truck weigh station. And if your data will be traveling a long distance – for instance between buildings or from one station to another – then you’re better off with a single-mode fiber cable.
