Cisco QSFP-100G-LR4-S Compatible 100GBASE-LR4 QSFP28 1310nm 10km SMF LC DOM Optical Transceiver Module
Cisco QSFP-100G-LR4-S compatible optical transceiver is a parallel 103.1Gbps Quad Small Form-factor Pluggable QSFP28 module for use in 100GBASE Ethernet. QSFP28 LR4 provides 100Gb/s throughput up to 10km over single-mode fiber (SMF) with host FEC using 1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm wavelength. This transceiver is fully compliant with QSFP28 Multi-Source Agreement (MSA), IEEE 802.3ba 100GBASE-LR4 and CAUI-4 standard. Its electrical interface is MSA compliant 38-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex QSFP28 transceiver implements 4 independent 25.78125 Gbps transmit and receive channels in each wavelength for an aggregate 100 Gbps data rate. Built-in Digital Diagnostic Monitoring (DDM) support is present for real-time performance monitoring via 2-wire Interface (TWI/I2C). Our modules are factory pre-programmed for compatibility, perform identically to original Cisco QSFP-100G-LR4-S transceivers.
