The US Transceivers compatible QSFP-40G-CSR-S is a 40GBASE-CSR QSFP+ transceiver module designed for high-speed optical interconnects over multimode fiber. Operating at an 850 nm wavelength using a parallel SR4-style architecture, this module supports link distances up to 400 meters over OM4 multimode fiber and up to 300 meters over OM3, making it well suited for intra-data-center connectivity at extended reach compared to standard SR4 modules.
The US Transceivers compatible QSFP-40G-CSR-S features an MPO/MTP connector interface and delivers an aggregate data rate of 40 Gbps across four parallel 10 Gbps lanes. It includes Digital Optical Monitoring (DOM) support for real-time diagnostics and is fully TAA compliant, meeting RoHS, CE, and REACH regulatory standards.
This module is an ideal drop-in compatible replacement for use in enterprise core switching, data center top-of-rack deployments, high-performance computing clusters, and storage area network environments requiring reliable 40G multimode connectivity.
