OTDR TESTING ACCESSORY · LAUNCH / RECEIVE CABLE BOX
OTDR Launch Cable Box
OTDR launch cable boxes are designed to improve OTDR measurement accuracy by minimizing the impact of the OTDR launch pulse. Used as a launch/receive cable, this rugged field-ready box helps technicians test link loss, connector reflectance, and near/far-end events with better confidence.
