Complete Connect offer a complete SR4 fibre cabling solution including QSFP+ breakout cables via our M400 Series. The M400 Series MPO to LC multimode fibre breakout cable with Polarity 40G/10G (or 100G/25G) will allow direct connection between a QSFP+ 40GBase-SR4 transceiver and up to 4 x SFP+ transceivers or between a QSFP28 transceiver and 4 x SFP28 transceivers. QSFP+ and QSFP28 transceivers which support SR4 have ports with an MPO male connection. These require an MPO female connector cable such as the MTP connector from US Conec (other brands of MPO connector are available).

M400 Series uses only the MTP ELITE connector and LC low loss ferrules

The MPO connector used in the M400 Series is the MTP connector with an MT ELITE ferrule. Most brands of QSFP+ (QSP28) 40G/100G transceiver (such as Cisco, Juniper, Arista plus many more) use the same MT ferrule within the transceiver port and so the highest optical performance is ensured when using the M400 Series product range.  M400 Breakout Cables also enable QSFP+ ports to be connected to existing fibre networks via LC fibre patch panels.

Compatibility with QSFP+ transceiver modules

  1. All QSFP+ 40GBase-SR4 transceiver modules have ports with male connections (with guide pins).
  2. The MTP cable needs a female connector (no pins)
  3. Transceivers from the leading switch manufacturers such as CISCO, Juniper, Extreme, HP, Dell, Arista and Brocade all use an MT ferrule.
  4. All Complete Connect 40G cables use the MT Elite ferrule within the MTP 12 fibre connector. This provides the best optical connection with all major QSFP+ transceivers. Some MPO connectors wont perform as well.
