Cisco Compatible QSFP-100G-LR4-S Overview
The QSFP28-100GBaseLR4 is a 103/112 Gbps transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE P802.3ba standard and OUT-4. The module converts 4 input channels of 25/28 Gbps electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 103/112 Gbps optical transmission. Reversely on the receiver side, the module de-multiplexes a 103/112 Gbps 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 1295.56, 1300.05, 1304.58 and 1309.14 nm as members of the LAN WDM wavelength grid defined in IEEE 802.3ba. The high-performance cooled LAN WDM EA-DFB transmitters and high sensitivity PIN receivers provide superior performance for 100G applications up to 10km links and compliant to optical interface with IEEE802.3ba Clause 88 100GBASE-LR4 and OUT-4l1-9D1F requirements. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA).
