Description
The AddOn Cisco® ONS-SC-2G-37.4 compatible SFP transceiver delivers reliable OC-48 (2.488 Gbps) data rates over single-mode fiber (SMF) up to 80km at a 1537.40nm wavelength using an LC connector. Built to meet or exceed Cisco® OEM specifications, it provides seamless interoperability with Cisco® equipment.
This hot-swappable, easy-to-install module supports Digital Optical Monitoring (DOM) for real-time diagnostics of operating parameters. Designed with robust ESD protection, low EMI metal housing, and RoHS compliance, it ensures dependable performance in Ethernet over DWDM, access, metro, and enterprise network applications. TAA compliance makes it suitable for government procurement, and each unit is uniquely serialized, programmed, and backed by a limited lifetime warranty.
