MPO/MTP Fiber Interconnection Products FAQs

The increasing demand on today’s higher fiber counts has exploded the development of multi-fiber technology. FiberStore is one of the main manufacturing of MPO/MTP fiber patch cable and cassettes, and many other MPO/MTP fiber interconnection products, which engineers unique MTP solutions using 12, 24, 48 and even 72 fiber MTP ferrules.

What is an MTP Trunk Cable?
An MTP trunk cable provides 12 to 144 fibre connectivity, by using 12-fibre push/pull optical connectors, it minimized errors and reduced spaces. The MTP trunk cable allows for lower bend radii and smaller slack loops. It enables up to 6x the cable tray capacity over traditional bulkier cabling solutions, saving up to 65 percent space. MPO trunk cable features round furcation legs that provide easy routing and improved storage. With the small profile furcation plug, it allows stress free cable mounting, leaves no legs outside the housing and shipped with strain-relief mounting cradles.

What is MTP Extender/MTP Extension Trunk?
The MTP extension Trunk extend subsets of links from zone distribution into equipment zones, which feature pinned (male) MTP connector on one end and non-pinned (female) MTP connectors on the other. It pinned MTP side mates with trunks via MTP connector panels, while not pinned MTP side plugs into modules or harnesses.

What is MTP couplers?
MTP couplers are simple plastic rectangles that hold two MTP connectors together. One cable going into an MTP coupler needs to have a male connector. The other cable must have a female connector. MTP couplers can be either key-up to key-up, or key-up to key-down. MTP cable has a clip on the top of the connector. On a key-up to key-up coupler, the clips are pointed in the same direction on both of the cables. On a key-up to key-down coupler. On a key-up to key-down coupler, the clips are on opposite sides. This also affects the polarity of the signal. Key-up to key-up couplers invert polarity. Key-up to key-down couplers retain the original polarity. This was initially counter-intuitive to me. It made sense once I thought about it though.

What is MTP harness?
An MTP harness breaks out 12 fiber MTP terminations into LC duplex connectors. It connects to trunks through a pinned MTP connector plug into dual fiber electronics ports with LC uniboot duplex connectors. It is occupying less space than 6 duplex jumpers improve airflow for cooling efficiency. By easing handling of cable connections on high-fibre count SAN directors and switch blades, it enables higher density in equipment patch panels. MTP harnesses are available in two lengths: short harness legs for minimal cable slack and long harness legs for mounting flexibility within a cabinet.

CWDM DWDM Networking Solutions

Wavelength division multiplexing is a cost effective and efficient way for expanding the fiber optic transmission capacity, because it allows using current electronics and current fibers and simply shares fibers by transmitting different channels at different color (wavelength) of light.

Wavelength Division Multiplexing, WDM is a technique that multiplexing several signals over a single fiber optic cables by optical carriers of different wavelength, using light from a laser or a LED. According to the number of wavelengths it supports, there are Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM).

CWDM was introduced as a low-cost approach to increasing bandwidth utilization of the fiber infrastructure. By using several wavelengths/colors of the light, 18 channels are viable and defined in the ITU-T standard G.694.2. CWDM systems typically provide 8 wavelengths, separated by 20nm, from 1470nm to 1610nm.

Benefits of CWDM
Passive equipment that uses no electrical power
Extended Temperature Range (0-70C)
Much lower cost per channel than DWDM
Scalability to grow fiber capacity with little or no increased cost
Protocol Transparent
Simple to install and use

Drawbacks of CWDM
16 channels may not be enough
Passive equipment offers no management capacities

DWDM packing WDM channels denser than in CWDM systems, 100 GHz spacing (approx. 0.8nm), more channels and higher capacity can be achieved using DWDM. IUT-T recommendation G.694.1 defines the DWDM channels spectrum. DWDM comes in two different versions: an active solution and a passive solution. An active solution is going to require wavelength management and it a good fit for applications involving more than 32 lines over the same fiber. In most cases, passive DWDM is looked at as a more realistic alternative to active DWDM.

Benefits of DWDM
Up to 32 channels can be done passively
Up to 160 channels with an active solution
Active solutions typically involve optical amplifiers to achieve longer distances

Drawbacks of DWDM
DWDM is very expensive
Active solutions require a lot of set-up and maintenance expense
“Passive” DWDM solution still requires power

Optical Add/Drop Multiplexing (OADM)
By optical add/drop multiplexing techniques, wavelength channels may be added and dropped at intermediate nodes using passive optical components only. Optical Add/Drop Multiplexers are used in WDM Systems for multiplexing and routing fiber optic signals. They can multiplex several low-bandwidth streams of data into a single light beam, and simultaneously, it can drop or remove other low-bandwidth signals from the stream of data and direct them to other network routers. There are CWDM OADM and DWDM OADM.

FiberStore offer a wide range of WDM optical networking products that allow transport of any mix of service from 2Mbps up to 200Gbps. Our highly reliable WDM/CWDM/DWDM products include CWDM multiplexers and demultiplexer, DWDM Multiplexers and demultiplexers, CWDM & DWDM Optical Add-drop Multiplexer, Filter WDM modules, CATV amplifier, OEO converters as well as many other most demanding CWDM DWDM networking infrastructure equipment.

Are Your Sure that You Have Chosen the Truly Low Smoke Non Halogen Cables

This article will guide to buy the truly low smoke halogen free cable, which is fully compliant with IEC standards and ultimately offers maximum safety and assurance in application. Awareness of the impact of smoke and harmful gases emitted during a fire has led to a growing demand for an alternative to more traditional plastic halogenated cable constructions.

Although low smoke and flume cables are commonplace, however, in the event of a fiber, these cables can still release toxic and corrosive gases. In the next text, we will tell you the difference between low smoke non halogen or low smoke and halogen:

It is true to state that a cable can have low smoke characteristics so that in the event of a fire, it will not release the dense smoke plumes seen with a traditional PVC cable. However, cable can be low smoke and fume and yet still release toxic and corrosive gases when ignited. Despite its low smoke generation, this classification of cable, commonly known as LSF (Low Smoke and Fume) still typically contains PVC based compounds, making it exempt from halogen free compliance.

The fact is cables which have PVC in their insulation or cable jacket are not compliant and cannot be deemed to low smoke non halogen. If they contain PVC, they are not halogen-free.

Stringent fire requirements, environmental concerns and new legislation have resulted in an increased demand for both low smoke and low smoke non halogen cables. This increase in demand has also led to a growth in the number of cable manufacturers and suppliers in the market.

A low smoke cable and a low smoke non halogen cable are often confused people as a multitude of cables available and the industrial abbreviations used to describe them. Whilst a low smoke cable is acceptable in some industries and applications, for maximum safety, fully compliant low smoke non halogen cable from a reputable cable manufacturer is recommended. A high performance low smoke non halogen cable can bring benefits in addition to compliance, particularity in the case of flame retardants which is vital to help prevent the spread of fire.

Conformity to the IEC standard 60332-1-2 is a fundamental requirement for flame retardants for communications cables whether halogenated or not; however, superior quality Low Smoke Non Halogen cables can achieve a higher rating to the IEC standard 60332-3-24. Superior flame retardancy to reduce the spread of fire, wider operating temperatures for confident use in varying temperature applications and improved tensile strength for durability can all be achieved from a premium quality cable designed for total reliability and safety.

Reputable fiber optic cable supplier will build these additional benefits into their cable design and manufacturing processes. Process capability does not necessarily bring process stability, consistent manufacturing quality is vital for assured performance and Flame Retardant Low Smoke Non Halogen compliance.
