The US Transceivers compatible QSFP-40G-ZR4-I is a 40GBASE-ZR4 QSFP+ optical transceiver designed for long-reach single-mode fiber applications. Operating across four CWDM wavelengths in the 1271 nm to 1331 nm range, this module delivers 40 Gbps aggregate throughput over distances up to 80 km, making it well suited for extended metro and enterprise wide-area deployments.
Built to industrial temperature standards, the QSFP-40G-ZR4-I operates reliably from -40 to 85 deg C, ensuring stable performance in thermally demanding environments such as outdoor cabinets and ruggedized network installations. The module features an LC Duplex connector interface and supports Digital Diagnostic Monitoring (DDM) for real-time visibility into optical performance parameters.
This US Transceivers compatible module is TAA compliant and meets RoHS, CE, and REACH requirements. It is a cost-effective, fully compatible alternative for use in Cisco-based network infrastructures requiring long-distance 40G connectivity.
