150m Single Mode OTDR Launch Cable, SC UPC/APC Connector, 492.1ft Optical Test Extension Jumper for Precision Network Analysis

150m (492.1ft) single‑mode OTDR launch cable designed to eliminate the OTDR blind zone and enable accurate measurement of near‑end connection loss and reflectivity. Fitted with SCUPC‑SCAPC single‑mode connectors and optimized for single‑mode testing at 1310/1550nm. A push‑cover design makes it simple to remove the jumper for use and to press it back in for compact storage after rewiring. The cable length provides ample reach for testing multiple fiber runs, while the compact, lightweight construction makes it easy to carry and use across various electrical applications.
