1KM SC/UPC-LC/UPC Fiber Optic Extensi

1KM SC/UPC-LC/UPC Fiber Optic Extension Cable – OTDR Launch Cable Test Lead

Improve the accuracy and reliability of fiber optic testing with the 1KM SC/UPC to LC/UPC Fiber Optic Extension Cable / OTDR Launch Cable Box. Designed for telecommunications technicians, fiber installers, network engineers, and fiber optic specialists, this professional test lead can be used as both a launch and receive cable during OTDR testing.

The 1KM fiber length helps overcome the OTDR`s initial dead zone, providing improved visibility of near-end and far-end connections and enabling more accurate measurement of connector loss, insertion loss, and reflectivity.

The fiber is neatly stored inside a rugged yellow hard-shell protective enclosure with sealing protection, helping keep the cable organized, clean, and protected during transportation and demanding field applications.

Key Features
1KM / 1000M Fiber Length – Provides extended fiber length for professional OTDR testing.
OTDR Launch & Receive Cable – Suitable for both launch and receive-end testing applications.
OTDR Dead Zone Reduction – Helps overcome the initial testing blind area for improved near-end connector measurement.

How the OTDR Launch Cable Works

The launch cable is connected between the OTDR and the fiber link under test. The additional 1KM fiber length helps move the OTDR`s initial dead zone away from the testing equipment, allowing technicians to obtain a clearer measurement of the near-end connector.

When used as a receive cable at the far end, it can also assist with evaluating the far-end connector, providing a more complete assessment of the fiber link.

Rugged Protective Housing

The 1KM fiber is neatly coiled inside a durable yellow hard-shell enclosure designed for professional field use. The housing helps:

Keep the fiber securely organized
Reduce tangling and unnecessary bending
Protect the cable during transportation
Shield the internal spool from dust and moisture
Reduce the risk of physical damage
Make storage and deployment easier
