5-Pack LC/UPC OM4 Loopback Testers

This set of five LC/UPC duplex loopback adapters uses OM4 multimode fibre for fast port diagnostics and transceiver verification. Network engineers and data-centre technicians use them to confirm signal integrity across multiple ports during deployment or routine maintenance. The plug-and-play design suits enterprise, telecom and laboratory environments.

OM4 50/125 µm Multimode Construction

Each adapter contains 50/125 µm OM4 fibre that supports high-speed short-range optical transmission with low insertion loss. Standard LC/UPC connectors mate securely with switches, transceivers, routers and optical test instruments. The compact, durable housing withstands repeated insertion cycles in dense patch panels and test benches.

Replaces Single Ad-Hoc Loopback Cables

The five-unit pack eliminates the need to source individual loopback cords for multi-port qualification, reducing test-setup time and spare-parts inventory. The jump is worth it when a project requires simultaneous verification of several transceiver ports or when a lab needs a ready-to-hand set for recurring fibre-health checks.

Questions about this item

What fiber standard does the OM4 multimode loopback support for short-range transmission?

The adapter uses 50/125 micron OM4 multimode fiber for high-speed short-range optical network testing.

Which connector type fits this duplex loopback adapter for port diagnostics?

Standard LC/UPC duplex connectors plug directly into fiber switches, transceivers, routers, and optical test instruments.

How do you install the loopback plug for transceiver verification without damaging the ferrules?

Align the LC/UPC key, insert straight until the latch clicks, and avoid angled pressure that can chip the ceramic ferrule end-face.
