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

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

Improve the accuracy of your fiber optic testing with the 1KM SC/UPC to SC/UPC Fiber Optic Extension Cable / OTDR Launch Cable Box. Designed for fiber technicians, network installers, and engineers, this professional OTDR test lead helps eliminate the OTDR`s initial blind zone, allowing accurate measurement of near-end and far-end connector loss, insertion loss, and reflectivity.

The cable uses a continuous single optical fiber strand with no fusion splice in the middle, helping maintain consistent optical performance and signal integrity throughout the 1KM length.

Housed inside a rugged yellow hard-shell protective enclosure, the cable is designed for field use and provides protection against water, dust, pressure, contamination, falls, and demanding working environments.

Key Features
1KM / 1000M Fiber Length – Provides sufficient cable length for professional OTDR testing applications.
OTDR Launch & Receive Cable – Helps overcome the OTDR launch blind zone and improves measurement accuracy.
Reduces Testing Blind Spots – Enables better visibility of near-end and far-end connections during fiber link testing.
No Middle Fusion Splice – Continuous single fiber strand without an internal fusion joint helps maintain consistent optical performance.
SC/UPC to SC/UPC Connectors – Supplied with dual SC/UPC connectors and protective dust caps.
Low Signal Attenuation – Designed to provide reliable optical signal transmission during testing.
Rugged Protective Housing – Yellow hard-shell enclosure provides protection for the coiled fiber during transportation and field use.
Cable Management System – Internal cable holders and wire binding buckles help keep the fiber securely organized.

How the OTDR Launch Cable Works

An OTDR launch cable is connected between the OTDR and the fiber link under test. The additional fiber length allows the OTDR to properly measure the first connector and helps move the initial OTDR blind zone away from the device, providing a more accurate assessment of the near-end connector.

It can also be used as a receive cable at the far end of the fiber link to help evaluate the final connector and overall link performance.

Rugged Protective Case

The 1KM fiber is neatly stored inside a compact protective enclosure designed for field technicians. The housing includes:

Protective hard-shell enclosure
Internal cable holders
Secure wire binding buckles
Sealing components
Integrated metal carabiner clip
Compact and portable design

This helps protect the delicate fiber from unnecessary bending, tangling, dust, moisture, and physical damage during transportation and deployment.
