Portable OTDR Launch Cable Box (Press Cover) — 500m / 1640.4ft Single-Mode Test Cable for 1310/1550nm

Designed to eliminate the OTDR blind spot, this portable launch cable provides a continuous test lead with no joints in the middle of the optical fiber. Compact and lightweight, it’s easy to carry and deploy on-site. The press-cover mechanism lets you pop the lid to pull out the cable for use, then press again after rewinding to conceal the lead and keep the unit tidy. Compatible with single-mode operation at 1310nm and 1550nm, the launch fiber is intended for measuring loss and reflectivity of near-end connections and for remotely inserting lossless fiber segments during OTDR testing. The housing is molded from durable ABS, offering resistance to wear and scratches for long service life. Ideal for cable television networks, telecommunications networks, computer fiber-optic networks and optical testing equipment, etc.
