QSFP28 100G ER4 optical transceiver, single-mode, LAN-WDM 4 aggregate 25G channels, 40km, QSFP-10040-ER4 max-splice-tray-no_9 and the XL holds aboutProduct description The QSFP 10040 ER4 is a long range single mode 100G QSFP28 optical module compatible with the 100GBase ER4 specifications. It uses 4 LAN WDM 25G lasers running 1290~1310nm and combining them through a built in mux demux. Each wavelength has 25Gbps for a total speed of 100G available on the QSFP28 interface. Unit can reach up to 40km distances on G. 652 types of SMF. The transceiver has been tested and found compatible on 100G
