Questions & Answers

  • Why your juniper SFPP-10G-CWDM1551 compatible CWDM SFP+ is 1551nm while Juniper original is 1544.5 nm to 1557.5 nm?
    1544.5 nm to 1557.5 nm refers to the wavelength range of the CWDM module. The CWDM wavelength range is ±6.5. The 1551nm band you bought is 1,544.5~1557.5nm. Our module and the original Juniper module have the same wavelength.
  • Is cleaning the optical connector of a transceiver essential? How should the 10G CWDM SFP+ transceivers be cleaned?
    Accumulation of dust and contaminants on transceiver connectors can lead to issues like diminished optic launch power. To promote optimal connectivity, QSFPTEK highly advises cleaning both connectors whenever disconnecting and reconnecting is done.
  • What is the operating temperature of this 10G CWDM SFP+ transceiver?
    It works at commercial temperatures from 0°C to 70°C.
