Questions & Answers
  • Q:

    Is it compatible with FS S5850-32S2Q Switch? By Brockman on 04/23/2020

    A:

    Yes, it is compatible with FS S5850-32S2Q. By FS on 04/23/2020

  • Q:

    Does this work in a 1310nm port of a DWDM filter? By Mattias.Lindgren on 07/10/2019

    A:

    Thanks for your question. #36173 has a ±10nm band, which can meet the DWDM filter transmission requirements. So it can work in the 1310nm port of the DWDM filter. By FS on 07/11/2019

  • Q:

    Is this using multiple frequencies or a single 1310nm frequency? By matt on 09/12/2018

    A:

    Thanks for your question. Our 40G ER4 transceiver use multiple frequencies: 1264.5-1277.5nm, 1284.5-1297.5nm, 1304.5-1317.5nm, 1324.5-1337.5nm. By FS on 09/13/2018
