Description
The AddOn Gigamon® QSF-503 Compatible QSFP+ Transceiver delivers reliable, high-speed 40GBase-LR4 Ethernet connectivity over single-mode fiber (SMF) with a reach of up to 10 kilometers. Operating on wavelengths from 1270nm to 1330nm via a duplex LC connector, this hot-pluggable module is designed for seamless integration into your existing network infrastructure.
Each transceiver is programmed, uniquely serialized, and rigorously tested for data traffic and application performance to ensure identical initialization and operation to the OEM equivalent. It features Digital Optical Monitoring (DOM) for real-time diagnostics of critical parameters and supports SFF-8436 compliance for guaranteed interoperability.
Engineered for access and enterprise environments, the QSF-503-AO is RoHS compliant, lead-free, and TAA compliant, making it an ideal choice for government and commercial deployments that demand robust, high-performance optical networking solutions.
