Long Reach Multimode

1990-4485 Overview

The HP 1990-4485 10GBase-LRM SFP+ transceiver provides reliable 10Gbps connectivity over multi-mode fiber with extended reach compared to traditional short-range optics. Operating at 1310nm, it supports up to 220 meters on legacy OM1/OM2 fiber, making it especially useful in environments where older cabling infrastructure is still in use. With a duplex LC interface and hot-pluggable SFP+ form factor, this module ensures simple installation and integration into HP switches, servers, and storage platforms. It is a cost-effective solution for enterprises and data centers looking to upgrade to 10GbE performance without fully replacing their existing MMF cabling, offering both compatibility and efficiency for backbone and access layer applications.
