JFOPT's QSFP+ 40G LR4 optical transceiver module is developed and produced based on the Ethernet IEEE 802.3ba and the SFF-8436. The transmiter of QSFP+ module converts 4 channels electrical signals into 4 channels CWDM optical signals, and multiplexes them into 1 fiber to achieve 40Gb/s transmission. At the receiving end, the module demultiplexes the 40Gb/s optical signal into 4 channels CWDM optical signals, and converts them into 4 channels electrical signals for output. The center wavelengths of the 4 channels CWDM are 1271nm, 1291nm, 1311nm and 1331nm.
