OTDR Fiber Rings
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 150 m to 1 km (or longer) in length. Because very long
test cables are impractical to transport and use, AFL offers coiled lengths of 50 µm
multimode, 62.5 µm multimode, or single-mode fiber packaged in compact rings.
Fiber Rings of 150 m of fiber are ideal for premises fiber network test applications.
Fiber Rings of 500 m and 1 km of single-mode fiber are designed for broadband,
long haul fiber network test applications.
