Allied Telesis AT-QSFPLR4 Compatible 40Gbps QSFP 40GBASE-LR4 1310nm 10km SMF Duplex LC DDM/DOM Optical Transceiver Module Allied Telesis AT-QSFPLR4 compatible optical transceiver is a parallel 40Gbps Quad Small Form-factor Pluggable QSFP module for use in 40GBASE Ethernet network. QSFP LR4 provides 41.2Gb/s throughput up to 10km over single-mode fiber (SMF) using 1271nm, 1291nm, 1311nm, 1331nm wavelength. This transceiver is fully compliant with QSFP Multi-Source Agreement (MSA), IEEE 802.3ba 40GBASE-LR4 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 10.3125Gbps transmit and receive signal channels in each wavelength for an aggregate 41.25Gbps data rate. Built-in Digital Diagnostic Monitoring/Digital Optical Monitoring (DDM/DOM) support is present for real-time performance monitoring via 2-wire (TWI/I2C) interface. Our modules are factory pre-programmed for compatibility, perform alternatively to genuine Allied Telesis AT-QSFPLR4 transceivers.
