    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 *** on 07/11/2019

    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 S***u on 09/13/2018

    Besides the price advantage we have compared to branded transceivers, FS.COM compatible transceivers also maintain the same performance and reliability. To satisfy our customers' needs of high performance, all of our transceivers are tested multiple times in mainstream original brand switches in our test center before shipped out.
