The US Transceivers compatible QSFP-40G-ER4 is a high-performance 40GBASE-ER4 QSFP+ transceiver module designed for long-reach single-mode fiber applications. Operating over four CWDM wavelengths in the 1270 nm to 1330 nm range, this module supports data rates up to 40 Gbps and delivers reliable transmission over distances up to 40 km, making it well suited for extended reach enterprise and carrier network deployments.
Built in the compact QSFP+ form factor, this module uses an LC Duplex connector interface and is fully compliant with IEEE 802.3ba 40GBASE-ER4 and QSFP+ MSA standards. TAA compliance makes it appropriate for US government and federally funded network projects. Digital Diagnostic Monitoring (DDM/DOM) provides real-time visibility into optical performance parameters including temperature, voltage, and optical power levels.
US Transceivers compatible QSFP-40G-ER4 modules are manufactured to meet or exceed OEM specifications, offering a cost-effective drop-in replacement for use in data center interconnects, enterprise core networking, metropolitan area networks, and carrier aggregation applications.
