M310 Series MTP® trunk cables form the backbone to the M Series solution. They are designed for a tool-less installation with MX and M310 modular cassettes or MX and M310 couplers and utilise Click-2-Connect® technology for a fast and simple way to grow the network.

MPO MTP® ELITE® low loss connectors with level 6 multistage termination

MTP® trunk cables use a lightweight but robust micro core fibre cable and MTP® connectors. They are about 65% lighter and 60% smaller in diameter than traditional tight buffered or loose tube fibre and gives the ability to install more fibre into less space. All trunk cables have a full lifetime guarantee and are protected by the Complete Connect warranty. Every trunk cable is supplied with a full test certificate and is traceable though a unique serial number.

Further Information

Compatibility with LC cassette modules

  1. M310 trunk cables offer instant connectivity when used with M310 LC modular cassettes
  2. M310 trunks are compatible with other MTP based systems such as Panduit, Corning, Siemon plus many others
  3. The MTP trunks can have either male or female connectors
  4. There are 3 types of cable polarity: A, B or C. Complete Connect will ensure the correct polarity is provided.
  5. All Complete Connect cables use the MT Elite ferrule within the MTP fibre connector. This provides the best optical connection possible.

Maximum transmission distances

  1. The IEEE standard states maximum distances based on loss budgets for OM3, OM4 and singlemode transmission.
  2. Distances vary depending on a number of factors including no. of mated connector pairs and cable routing.
  3. Complete Connect’s technical team can provide all the relevant information concerning loss budgets and allowable distances.

Testing using Loopback adaptor cables

  1. MTP loopback cables can be used to test individual trunk cables.
  2. LC loopback adaptors can be used to test full channels.
