The US Transceivers compatible QSFP-40G-ER4-I is a 40GBASE-ER4 QSFP+ transceiver engineered for extended-reach single-mode fiber deployments at 40 Gbps. Supporting link distances of up to 40 km over SMF, this module utilizes LAN WDM technology across four wavelengths in the 1295 nm to 1310 nm range, making it well suited for long-haul enterprise and carrier-grade network connections. The industrial temperature rating ensures stable operation from -40 to 85 deg C, ideal for demanding environments.
The US Transceivers compatible QSFP-40G-ER4-I features an LC Duplex connector interface and supports Digital Diagnostic Monitoring (DDM/DOM) for real-time visibility into module performance parameters. It is TAA compliant and meets RoHS, CE, and REACH regulatory standards. This module is designed as a fully compatible replacement for Cisco QSFP-40G-ER4-I and integrates seamlessly into compatible QSFP+ port equipment without firmware or configuration changes.
