The US Transceivers compatible QSFP-40G-LR4-S is a 40GBASE-LR4 QSFP+ optical transceiver module designed for high-speed 40 Gigabit Ethernet applications over single-mode fiber. This module utilizes four CWDM wavelengths centered at 1271 nm, 1291 nm, 1311 nm, and 1331 nm, multiplexed onto a single LC Duplex connector, supporting link distances of up to 10 km.
Built to TAA compliance standards, this QSFP+ transceiver is a cost-effective, fully compatible alternative for use in networking equipment that supports the QSFP-40G-LR4-S specification. It supports Digital Diagnostic Monitoring (DDM) for real-time visibility into key optical parameters including temperature, voltage, TX power, and RX power.
This module is ideal for enterprise core networking, data center interconnects, and service provider deployments requiring reliable long-reach 40G connectivity over SMF infrastructure. It complies with IEEE 802.3ba and relevant MSA standards, and meets RoHS, CE, REACH, and TAA requirements.
