Description
This AddOn Gigamon Systems® Q28-503 compatible QSFP28 transceiver delivers 100GBase-LR4 throughput up to 10 km over single-mode fiber (SMF) using a wavelength range of 1295 nm to 1309 nm via an LC connector. Designed for seamless interoperability, it is guaranteed to be 100 % compatible with the original Gigamon Systems® transceiver.
The module is hot-pluggable, uniquely serialized, and undergoes comprehensive data-traffic and application testing to ensure identical initialization and performance. It supports Digital Optical Monitoring (DOM) for real-time access to critical operating parameters. TAA-compliant and built to MSA standards, this transceiver is ideal for enterprise, access, and high-performance 100 G Ethernet applications.
Backed by AddOn’s limited lifetime warranty, this module combines reliability, exceptional ESD protection, and low EMI performance — making it a trusted solution for mission-critical optical networking environments.
