JFOPT’s QSFP28 100G(CWDM4) FR4 optical transceiver is developed and produced based on the 100G Ethernet IEEE 802.3bm. The transmiter of QSFP28 module converts 4 lanes 25Gb/s electrical signals into 4 CWDM optical signals, and multiplexes them into 1 fiber to achieve 100Gb/s transmission. At the receiving end, the module demultiplexes the 100Gb/s optical signal into 4 channels CWDM optical signals, and converts them into 4 lanes 25Gb/s electrical signals for output. The center wavelengths of the 4 channels CWDM are 1271nm, 1291nm, 1311nm and 1331nm.
