1KM SC/APC-FC/UPC Fiber Optic Extensi

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

Enhance the accuracy of your fiber optic testing with the 1KM SC/APC to FC/UPC Fiber Optic Extension Cable / OTDR Launch Cable Box. Designed for telecommunications technicians, fiber installers, network engineers, and optical testing professionals, this high-quality 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, allowing technicians to obtain more accurate measurements of near-end and far-end connector loss, insertion loss, and reflectivity.

The fiber is neatly housed inside a rugged yellow hard-shell protective enclosure, helping protect the coiled cable and connectors 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.
Dead Zone Reduction – Helps overcome the OTDR`s initial blind zone for more accurate near-end connector measurements.
Low Signal Attenuation – Approx. 0.5dB/km for stable optical signal transmission during testing.
Hybrid SC/APC to FC/UPC Connectors – Equipped with an SC/APC green connector and FC/UPC metallic connector, both with protective dust caps.
Rugged Protective Case – High-visibility yellow hard-shell enclosure provides protection during transportation and field deployment.
Field-Ready Protection – Designed to resist water, dust, pressure, falls, and demanding working environments.
Integrated Cable Management – Internal cable holders and binding buckles keep the fiber securely coiled and organized.
Portable Design – External metal carabiner hook allows convenient attachment to tool bags, belts, or other equipment.
Soft Carrying Pouch Included – Provides convenient storage and transportation.
Customizable Configuration – Custom lengths, connector combinations, fiber types, and single-mode/multimode configurations can be requested.

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, providing better visibility and measurement of the near-end connector.

It can also be used as a receive cable at the far end of the link, helping technicians evaluate the final connector and obtain a more complete measurement of the fiber connection.

Rugged Protective Housing

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

Protect the fiber during transportation
Keep the cable neatly organized
Reduce tangling and unnecessary bending
Protect against dust and moisture
Reduce the risk of physical damage
Make deployment and storage easier
