BLUELAN BlueOptics Fiber Optic Loopback Adapter OM3 50/125µm Multimode SC/UPC Duplex, Aqua/Turquoise, Ceramic Ferrule, -40°C to +85°C (BOLBSCOM3)

Network troubleshooting and diagnostics often require a reliable way to test fiber optic links without relying on remote equipment. The BLUELAN BlueOptics Loopback Adapter for OM3 multimode fiber provides a simple, effective solution by routing the transmit signal back to the receiver, enabling verification of link integrity and performance. Designed for SC/UPC duplex connections, it features a 50/125µm core/cladding and a zirconia ceramic ferrule for precise alignment and low insertion loss. Its aqua/turquoise housing complies with industry color coding for OM3 multimode, and it operates reliably across a wide temperature range from -40°C to +85°C.

Who is it for

This loopback adapter is intended for network engineers, technicians, and IT professionals who need to test, diagnose, and troubleshoot fiber optic networks, particularly those using OM3 multimode cabling with SC/UPC connectors.
