QSFP28 100GBASE ER4 1310nm 40km Dual LC Fibre Optic Transceiver Module
100G 40km QSFP28 ER4 optical transceiver is designed for use in 100-Gigabit Ethernet links up to 30km without FEC or 40km with FEC on Single Mode Fiber (SMF). It is compliant with the QSFP28 MSA, 4WDM-40 MSA, and relevant portions of IEEE 802.3bm. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP28 MSA. It converts 4 input channels of 25.78125Gb/s electrical data to 4 channels of LAN-WDM optical signals and then multiplexes them into a single channel for 103.125Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 103.125Gb/s optical input into 4 channels of LAN-WDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 LAN-WDM channels are 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm as members of the LAN-WDM wavelength grid defined in IEEE 802.3ba.
