400G QSFP-DD SR8 70m OM3 With FEC, 400G Ethernet Enterprise Networking
This product is a parallel 400Gb/s QSFP-DD optical module. It provides increased port density and total system cost savings. The QSFP-DD full[1]duplex optical module offers 8 independent transmit and receive channels, each capable of 53.125Gb/s operation for an aggregate data rate of 400Gb/s on 70 meters of OM3 multi-mode fiber. An optical fiber cable with an MTP/MPO-16 connector can be plugged into the QSFP-DD SR8 module receptacle. Proper alignment is ensured by the guide pins inside the receptacle. The cable usually cannot be twisted for proper channel to channel alignment. Electrical connection is achieved through an QSFP-DD MSA-compliant edge type connector
