1KM LC/UPC to LC/UPC Fiber Optic Extensi

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

The 1KM LC/UPC to LC/UPC Fiber Optic Extension Cable / OTDR Launch Cable Box is a professional fibre optic testing accessory designed to improve the accuracy of OTDR (Optical Time-Domain Reflectometer) measurements. By connecting between the OTDR and the fibre link under test, the launch cable helps overcome the OTDR`s initial dead zone, allowing technicians to accurately measure near-end connector loss, reflectance and overall fibre link performance.

With 1 kilometre of single-mode fibre, LC/UPC connectors and a rugged protective hard-shell enclosure, this OTDR launch cable is ideal for telecommunications technicians, fibre installers, network engineers and field maintenance teams.

Key Features
1KM Fibre Length: Provides a generous 1000m test lead for professional OTDR testing applications.
OTDR Launch Cable: Helps overcome the OTDR dead zone and provides more accurate measurement of the first connector and near-end section of the fibre link.
Near-End & Far-End Testing: Can be used as a launch and receive cable arrangement for evaluating both ends of a fibre link.
LC/UPC Connectors: Equipped with LC/UPC to LC/UPC single-mode fibre connections.
Low Attenuation: Approximate fibre attenuation of ≤0.5dB/km, helping maintain test signal integrity.
Rugged Protective Case: Fibre is housed inside a durable hard-shell enclosure designed to protect the cable during transportation and field use.
Water & Dust Resistant Design: Protective enclosure helps shield the internal fibre from harsh environmental conditions.
Pressure & Fall Resistant: Heavy-duty construction provides additional protection against impact and handling during field operations.
Integrated Cable Management: Internal coiled fibre storage with dual cable holders and binding buckles keeps the fibre organised.
Portable Design: Includes a metal carabiner clip for convenient attachment to equipment or a technician`s tool bag.
Protective Dust Caps: Helps keep the LC/UPC connectors clean and protected when not in use.
Custom Configurations Available: Length, connector type and fibre type can be customised depending on application requirements.

How an OTDR Launch Cable Works

An OTDR launch cable is placed between the OTDR instrument and the fibre link being tested. The additional fibre length allows the OTDR to move beyond its initial measurement dead zone, making it easier to evaluate the performance of the first connector and the beginning of the fibre link.

When used with a suitable receive cable at the far end, technicians can also evaluate the far-end connector and overall connection loss more accurately.

Rugged Field-Ready Design

The 1KM fibre cable is neatly wound inside a protective hard-shell enclosure, helping prevent tangling, excessive bending and accidental damage during transportation and installation.

The case includes dual cable holders and flexible binding buckles to keep the fibre securely organised. A built-in metal carabiner clip allows the launch box to be conveniently attached to a technician`s equipment or tool bag.
