    • To help item creation:

      End A TypeMale/Female (M/F)APC/UPCEnd Z TypeMale/Female (M/F)APC/UPCCable TypeNumber of Fiber Strands (F)Cable Length

      Example:
      MPO F APC to MPO F APC Type A 12F 6m = MPO Female pinned APC to  MPO Female pinned APC Type A 12 strands 6 meters

  • MPO cables are 12 strands of singlemode or multimode fiber housed within a single jacket or trunk (other fiber counts are available). It has its own IEC spec.
  • MTP is a brand name that falls within the MPO spec 
  • FS has a good polarity how to on their website (some of the below images came from FS)
  • Examples:
    • SM APC MPO to SM UPC LC breakout cable
    • SM APC MPO to SM APC MPO
  • Key:
  • Male vs. Female:
    • Coupled connectors must be matched male/female
  • Polarity:
  • Couplers
  • QSFP+
    • 40G QSFP+ can have the ability to breakout into 4x10G interfaces
    • See FlexOptix PLR4/QSFP+ 10G LR optics
