BLUELAN BlueOptics OM3 LC/UPC Duplex Multimode Fiber Loopback Adapter, Aqua, Ceramic Ferrule, -40°C to +85°C BOLBLCOM3

Testing and troubleshooting fiber optic networks often requires a way to verify link integrity without relying on a remote device. This BLUELAN BlueOptics loopback adapter provides a simple, reliable method to loop a transmitted signal back to the receiver on the same port, enabling quick validation of transceivers, patch panels, and cable assemblies.

Who is it for

Network engineers, data center technicians, and field installers who need to perform link testing, burn-in testing, or fault isolation on multimode fiber systems. It is particularly useful for OM3 10G Ethernet and high-speed multimode applications.

Main features

• LC/UPC duplex connector with ceramic ferrule for precise alignment and low insertion loss.
