The US Transceivers compatible QSFP-40G-PLR4 is a high-performance 40GBASE-PLR4 QSFP+ transceiver designed for single-mode fiber deployments requiring extended reach at 40G speeds. Operating over four parallel lanes at 1310 nm using a PSM4 (Parallel Single-Mode 4-lane) architecture, this module delivers an aggregate data rate of 40 Gbps with a maximum cable distance of up to 10 km over SMF.
Featuring an MPO/MTP connector interface, the US Transceivers compatible QSFP-40G-PLR4 supports Digital Diagnostic Monitoring (DDM/DOM), giving network operators real-time visibility into key performance parameters such as optical power, temperature, and voltage. The module is hot-pluggable and fully compliant with QSFP+ MSA mechanical and electrical specifications.
Built to meet TAA, RoHS, CE, and REACH compliance requirements, this module is an ideal cost-effective alternative for data center interconnects, enterprise core networking, campus backbones, and high-density switching environments where long-reach 40G connectivity is required.
