JFOPT’s QSFP28 100G (LAN-WDM) LR4 optical transceiver module is developed and produced based on the 100G Ethernet IEEE 802.3bm. The transmitter of QSFP28 module converts 4 lanes of 25Gb/s electrical signals into 4 LAN-WDM optical signals, and multiplexes them into 1 fiber to achieve 100Gb/s transmittion. At the receiving end, the module demultiplexes the 100Gb/s optical signal into 4 lanes LAN-WDM optical signals through a demultiplexer (DEMUX), and then converts them into 4 25Gb/s electrical signals.The center wavelength of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm. The 100G links is up to 10KM.
