Purpose-built to remove OTDR blind spots, this single-mode 1000m / 3280.8ft launch cable box delivers more accurate and dependable OTDR results for 1310nm and 1550nm testing. Equipped with SC UPC/APC connectors, it is intended for single-mode fiber measurements—checking loss and reflectance at near-end connections and allowing insertion of a lossless fiber segment remotely during OTDR runs. The compact, lightweight design makes the unit easy to transport and store. A simple press-to-open housing lets you quickly extend or rewind the cable for convenient operation. The enclosure is molded from premium ABS, offering resistance to wear, scratches, and weather so it stands up to varied field conditions.
