Transition Networks TN-GLC-LH-SMD Sfp Transceiver 1000BASE-LH

Product Description

The TRANSITION NETWORKS TN-GLC-LH-SMD is a Small Form-factor Pluggable (SFP) fiber optic transceiver designed for Gigabit Ethernet applications over single-mode fiber. Operating at the 1000BASE-LH standard, this module converts electrical data signals to optical signals for long-haul fiber transmission. It is sold as a single unit and is installed by network technicians and field engineers in switches, routers, and media converters that accept standard SFP slots. The compact form factor allows hot-swap installation without powering down the host equipment in most deployments.

This transceiver is suited for enterprise networking, data center interconnects, and industrial network infrastructure where single-mode fiber runs are required. The 1000BASE-LH designation indicates compatibility with long-reach single-mode fiber links, making it appropriate for campus backbone connections and inter-building fiber runs where extended distance is a requirement.

Key Features

• SFP form factor supports hot-swap installation in compliant host equipment
• 1000BASE-LH standard for Gigabit Ethernet over single-mode fiber
• Compact, pluggable design for use in SFP-capable switches, routers, and media converters
• Single-unit packaging suitable for individual port upgrades or replacements

Compatibility

Designed as an OEM-style replacement or upgrade SFP transceiver for network equipment with standard SFP slots supporting 1000BASE-LH single-mode fiber operation.

Installation Notes

Installation is performed by qualified network technicians familiar with fiber optic handling procedures. Before inserting or removing the module, confirm whether the host equipment supports hot-swap to determine if a system power cycle is required. Handle fiber end-faces and the transceiver optical port with care to avoid contamination, and use appropriate fiber inspection and cleaning tools prior to mating the connector. Follow the host equipment manufacturer guidelines and applicable data center or structured cabling standards during installation.
