How to choose QSFP-DD optics

  • QSFP-DD carries 400 Gb/s with a double row of electrical contacts
  • Most QSFP-DD ports also accept QSFP28 and QSFP+ modules; check the platform guide
  • SR8 uses MPO-16 multimode; DR4 uses MPO-12 single-mode; FR4 and LR4 use duplex LC
  • ZR and ZR+ coherent optics carry 400G over DWDM line systems
  • 400G DACs and AOCs are the simplest option for in-rack and adjacent-rack links

Frequently asked questions
