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 receives 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 1 km to 2 km (or longer) in length. Because very long test
cables are impractical to transport and use, FONGKO offers coiled
lengths of 50 um multimode, 62.5 um multimode, or single-mode fiber
packaged in compact rings. Fiber Rings of 1000 m of fiber are ideal
for premises fiber network test applications. Fiber Rings of 1 km
and 2 km of single-mode fiber are designed for broadband, long-haul
fiber network test applications.
