Fiber Spool for Launch Cable

Measuring an insertion loss of the near-end and / or far-end connection of a fiber optic link with an OTDR requires a launch and / or receive test cable. A launch cable, which connects the OTDR to the link under test, reveals the insertion loss and reflectance of the near-end connection. A receive cable, which connects to the far-end of the link, reveals the insertion loss and reflectance of the far-end connection. Launch and receive test cables can range from 0.5km to 50.4km  in length. Because very long test cables are impractical to transport and use, We offer coiled lengths of 50μm multimode, 62.5μm multimode, or single-mode fiber packaged in compact rings. Fiber Rings of 1 km of single-mode fiber are designed for broadband, long-haul fiber network test applications.
