Brocade 40G-QSFP-LM Compatible 40GBASE-LX4 QSFP+ 1310nm 150m/2km MMF/SMF LC DOM Optical Transceiver Module


Brocade 40G-QSFP-LM compatible optical transceiver is a parallel 41.2Gbps Quad Small Form-factor Pluggable QSFP+ module for use in 40GBASE Ethernet. QSFP+ LX4 provides 40Gb/s throughput up to 150 meters/2km over OM3 multi-mode fiber (MMF) / single-mode fiber (SMF) using 1271nm, 1291nm, 1311nm, 1331nm wavelength. This transceiver is fully compliant with QSFP+ Multi-Source Agreement (MSA), IEEE 802.3 40GBASE-LX4 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 Brocade 40G-QSFP-LM transceivers.
