$140.00

SKU: QSFP-40G-CSR4-US Categories: , , Brand:

The US Transceivers compatible QSFP-40G-CSR4 is a high-performance 40GBASE-CSR4 QSFP+ transceiver module designed for short-reach multimode fiber applications. Operating over four parallel lanes at 850 nm, this module delivers an aggregate data rate of 40 Gbps and supports link distances up to 400 meters over OM4 multimode fiber and up to 300 meters over OM3 multimode fiber.

Featuring an MPO/MTP connector interface, the US Transceivers compatible QSFP-40G-CSR4 is built for high-density deployments where space and power efficiency are critical. It supports Digital Diagnostic Monitoring (DDM) for real-time visibility into module performance, including temperature, voltage, and optical power levels.

This module is fully TAA compliant and meets RoHS, CE, and REACH regulatory standards, making it well suited for data center interconnects, enterprise core networking, high-performance computing clusters, and storage area network environments.
