Fiber Optic Patch Cord LC / UPC Loopback Test Cable Telecommunication Cutomized
Similar as fiber optic patch cords, fiber loopback can be with various jacket types and cable diameters, and they can be with different terminations and length. We make fiber optic loopbacks strictly according to industry standard. Each of the loopback is functionally tested before shipping. And we offer custom assemblies for fiber optic loopbacks such as custom connector configurations and special polishing.
You may find that loopback also has different types of optical connectors and fibers. Categorized by connectors, fiber optic loopback has SC, LC, MTRJ, E2000 types, etc. LC fiber optic loopback complies with the RJ-45 style interface. Having a low insertion loss, low back reflection and high precision alignment, LC fiber optic loopback is widely used all over the world. Another frequently used type is SC fiber optic loopback. Its connector is compliant to IEC, TIA/EIA, NTT and JIS specifications. Now it is the most popular loopback with low cost but high performance. In addition, to separate by fiber types, single-mode loopback (9/125) and multimode loopback (50/125, 62.5/125) are deployed for the application.
