Rewera OTDR Launch Box 300m / 984.3ft SCUPC SCAPC Single Mode Fiber Test Extension Jumper

Purpose-built to eliminate the OTDR test blind spot, this launch cable provides a reference jumper for accurate measurement of near-end connection loss and reflectivity. The assembly uses SCUPC SCAPC single mode connectors and is intended for single mode fiber testing at 1310/1550nm. A push-cover (press cover) design makes it simple to pull the jumper out for testing and, after rewiring, press the cover again to secure the jumper back inside the box. With 300m / 984.3ft of fiber, the extension offers ample length for use across multiple fiber runs. The compact, lightweight housing is easy to transport and deploy, making it suitable for various electrical applications.
