Miray’s QSFP-40G-ER4 is a 4-Channel CWDM 1300nm QSFP+ transceiver for 40GbE and InfiniBand DDR, QDR applications especially in Data Center & Storage networks. The transmitter converts 4-Channel 10G electrical input data to four CWDM optical signals and multiplex that into one 40G signal. The receiver de-multiplex the 40G signal reversely and converts that to 4-Channel 10G electrical output data. The techniques bring a compact transceiver module for an aggregate bandwidth of 40Gbps up to SMF 40km optical links.
