Buacoz 5 Pack SC/UPC Fiber Loopback Adapter Tester, OM3 Multimode Duplex - 50/125μm Fiber Optic Loopback Cable,Fiber Optic Cable Test Plug for Testing($27.29Value)

Description

Duplex SC multimode 9/125μm bending insensitive fiber optic loopback adapter with precision ceramic ferrule for maximum Return Loss, minimum Insertion Loss and high reliability. Built with premium optical cables and connectors, it offers low insertion loss (≤0.6db) and low return loss (≥20db), operating reliably across a wide temperature range of -40 to 75°C. The loopback tester is designed with a protective casing for the fiber optic cable, preventing bending or breakage and enhancing the adapter's durability during tests. Fully compliant with Telcordia and GR326 standards, and made from RoHS-compliant materials, ensuring safety and environmental friendliness. Versatile Applications: Ideal for fiber optic testing, network recovery, and system debugging. This LC connector loopback adapter is perfect for evaluating the performance of fiber optic cabling, SFP modules, equipment ports, or entire network devices. The fiber loopback is mainly used to test the signal return in the system or network system.
It can detect potential abnormalities in the network link by the signal return( the pairwise connected TX transmitting end-face send the signals back to the RX receiving end-face)。
Fiber Loopback Module can provide an economical solution for many fiber optic test applications.
