How to choose QSFP+ optics

  • QSFP+ carries 40 Gb/s as four 10G lanes
  • SR4 uses parallel multimode fibre with an MPO connector; BiDi variants use duplex LC
  • LR4 multiplexes four wavelengths onto single-mode fibre with LC connectors (about 10 km)
  • Breakout cables split one 40G port into four 10G SFP+ links

Frequently asked questions

What cabling does a 40G SR4 module need?

SR4 modules use parallel optics: an MPO/MTP multimode trunk with eight active fibres, rather than a duplex LC patch cord.
