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

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

Improve the accuracy of fiber optic testing with the 1KM SC/APC to SC/APC Fiber Optic Extension Cable / OTDR Launch Cable Box. Designed for telecommunications technicians, fiber installers, network engineers, and field-service professionals, this high-quality test lead can be used as both a launch and receive cable during OTDR testing.

The 1KM continuous 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 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 launch and receive-end testing applications.
OTDR Dead Zone Reduction – Helps overcome the initial testing blind area for improved near-end connector measurement.
Continuous Fiber Strand – Features a continuous optical fiber length with no internal fusion splice, helping maintain consistent optical performance.
Low Signal Attenuation – Approx. 0.5dB/km for reliable optical signal transmission.
Dual SC/APC Connectors – Pre-terminated with green SC/APC connectors and protective dust caps on both ends.
Rugged Protective Enclosure – Yellow hard-shell case helps protect the internal fiber during transportation and field deployment.
Field-Ready Protection – Designed to resist water, dust, pressure, and falls.
Integrated Cable Management – Internal cable holders and adjustable binding buckles help keep the fiber securely coiled and organized.
Portable Design – Integrated metal carabiner clip allows convenient attachment to a tool bag, belt, or other equipment.
Customizable Configuration – Custom cable lengths, connector combinations, 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 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.
