Cisco QSFP-40G-ER4 Compatible 40GBASE-ER4 QSFP+ 1310nm 40km SMF LC DOM Optical Transceiver Module
Cisco QSFP-40G-ER4 compatible optical transceiver is a parallel 41.2Gbps Quad Small Form-factor Pluggable QSFP+ module for use in 40GBASE Ethernet. QSFP+ ER4 provides 40Gb/s throughput up to 40km over single-mode fiber (SMF) using 1271nm, 1291nm, 1311nm, 1331nm wavelength. This transceiver is fully compliant with QSFP+ Multi-Source Agreement (MSA), IEEE 802.3bm 40GBASE-ER4 and XLPPI standard. Its electrical interface is MSA compliant 38-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex QSFP+ transceiver implements 4 independent 10.3125 Gbps transmit and receive channels in each wavelength for an aggregate 40 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-40G-ER4 transceivers.
