The US Transceivers compatible QSFP-40GE-LR4 is a high-performance 40GBASE-LR4 QSFP+ transceiver module designed for long-reach single-mode fiber applications. Operating across four CWDM wavelength lanes (1271 nm, 1291 nm, 1311 nm, and 1331 nm), this module delivers an aggregate data rate of 40 Gbps and supports link distances of up to 10 km over SMF using an LC Duplex connector interface.
Built to meet IEEE 802.3ba and QSFP+ MSA standards, the US Transceivers compatible QSFP-40GE-LR4 is engineered for seamless drop-in compatibility with supported network equipment. It features Digital Diagnostic Monitoring (DDM) for real-time performance visibility and operates within a standard 0 to 70 deg C commercial temperature range.
This module is TAA compliant and well suited for enterprise core networking, data center interconnect, and service provider aggregation deployments where reliable, high-bandwidth long-reach connectivity is required.
