Description
The AddOn Cisco® QSFP-40G-LR4-S-20 Compatible TAA 40GBase-LR4 QSFP+ Transceiver delivers reliable 40 Gigabit Ethernet connectivity over single-mode fiber (SMF) for distances up to 20 kilometers. Operating across 1270nm to 1330nm CWDM wavelengths, it utilizes 4 DFB laser channels and a 4-lane CWDM Mux/Demux design for robust, high-speed performance.
Engineered for seamless interoperability, this hot-swappable module is 100% compatible with the original Cisco® transceiver and supports Digital Optical Monitoring (DOM) for real-time diagnostics of key parameters. It complies with IEEE 802.3ba, QSFP+ MSA, and TAA requirements, making it an ideal solution for enterprise, data center, and access network applications. AddOn’s rigorous testing ensures guaranteed performance and reliability, backed by a limited lifetime warranty.
