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.
