The US Transceivers compatible QSFP-40G-PSM4-S is a 40GBASE-PSM4 QSFP+ transceiver module designed for high-speed optical networking over single-mode fiber. Operating at 1310 nm across four parallel lanes, this module delivers an aggregate data rate of 40 Gbps and supports link distances up to 10 km, making it well suited for long-reach data center and campus interconnect applications.
This module uses an MPO/MTP connector interface and transmits across four independent lanes at 10 Gbps each using PSM4 (Parallel Single Mode 4-lane) architecture. The US Transceivers compatible QSFP-40G-PSM4-S is built to meet IEEE 802.3 and PSM4 MSA standards, and is fully TAA compliant for U.S. federal procurement requirements.
Designed as a cost-effective, drop-in compatible replacement, this transceiver supports Digital Diagnostic Monitoring (DDM/DOM) for real-time performance visibility and operates across a standard 0 to 70 deg C commercial temperature range.
