KomShine OTDR Launch Cable (OLC®) Box
Available in lengths from 500 to 2000 meters.
OTDR Dead Zone Eliminator, Fiber Rings,Launch Lead, Pulse Suppressor,
OTDR launch cables are used with an OTDR to minimize the event dead zone and to allow measurement of the complete link loss of a fiber. Without an OTDR launch cable, the initial length of fiber and initial connector remain hidden. Top quality fiber optic launch cables serve as both a launch cable and a receive cable. When connected to the OTDR and to the link under test they can disclose the insertion loss and reflectance of both near-end and far-end fiber connections allowing end-to-end loss measurement. Also known as launch cords, launch leads, receive cables, fiber optic launch cables and fiber rings, these low cost OTDR launch cables are available in both multimode fiber and single mode Corning fiber versions. They are offered in a selection of lengths depending on need. It is suggested that the OTDR launch cable be slightly longer than the dead zone. Each OTDR launch cable features 1 meter pigtails, a portable lightweight ring design and a repositionable carabiner.
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.
Long lengths of test cables are impractical to transport and use, therefore NOYES designed coiled lengths of 50 µm multimode, 62.5 µm multimode, or single-mode fibre which are conveniently packaged in compact rings.
