Cisco QSFP-40G-ER4 X2 Transceiver Module QSFP 40GBASE-ER4 Transceiver LC 40KM QSFP-40G-ER4 specification QSFP-40G-ER4 is a transceiver module designed for 40km optical communication applications. The design is compliant to 40GBASE-ER4 of the IEEE P802.3ba standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data. Key Features Compliant with 40G Ethernet IEEE802.3ba and 40GBASE-ER4 Standard QSFP+ MSA compliant Compliant with QDR/DDR Infiniband data rates Up to 11.2Gb/s data rate per wavelength 4 CWDM lanes MUX/DEMUX design Up to 30km transmission on single mode fiber (SMF) Operating case temperature: 0 to 70oC Maximum power consumption 3.5W LC duplex connector RoHS compliant Products details and quality control: Pictures FAQ 1.
