    Round OTDR Launch Cable Box - Efficient Testing | HOLIGHT
    A round OTDR Launch Cable Box is a rugged, portable fiber optic reel used with an Optical Time Domain Reflectometer (OTDR) to eliminate initial "dead zones" and accurately measure fiber optic link performance, featuring coiled fiber (often 100m to 1km) in a compact, durable case with standard connectors (like SC, LC, FC) for field testing, ensuring precise loss and reflection readings on the tested line. 
    Key Functions & Features 
    • Dead Zone Elimination: The launch cable extends the fiber, allowing the OTDR's initial powerful pulse to reflect within the box, not the actual cable being tested, revealing details in the first few hundred meters.
    • Accurate Measurements: It creates stable conditions for measuring near-end insertion loss and reflectance, providing true link data.
    • Compact & Rugged: Designed for field use with waterproof, dustproof housing and often includes a carabiner for easy carrying.
    • Versatile: Available in various lengths (e.g., 100m, 500m, 1km) and connector types (SC, LC, FC, UPC/APC) to match different OTDRs and cables.
    • No Mid-Splices: High-quality boxes use continuous fiber with low-loss connectors, avoiding internal fusion splices for better results. 
    How It Works 
    1. Connect one end of the launch box cable to your OTDR.
    2. Connect the other end of the launch box cable to the fiber link you want to test.
    3. Run the OTDR test; the launch box absorbs the initial pulse, letting you accurately see the tested link's properties.

    What is the minimum length of launch cord for OTDR?
    Testing Long OTDR Links | Fluke Networks
    The table below shows examples of minimum lengths of launch cords for typical links. The Fluke Networks singlemode OTDR Launch Cords are 160 meters. If you need longer OTDR launch cords for the installation being tested (I.e. the links are longer than 35 Km), contact your cable supply.

    What is the difference between cable tester and OTDR?
    Fiber optic cable testing can be categorized based on the type of test being conducted: End-to-End Testing: Verifies light transmission capability and signal integrity over the entire length of the cable. OTDR Testing: Identifies the location and severity of faults within the cable or its connectors.

    What is the purpose of a launch cable?
    Essentially, the launch cable ensures that the pulse is launched into the fiber with consistent power. By providing this “smooth start,” the launch cable eliminates the inaccuracies caused by the unstable initial pulse, allowing the OTDR to gather more accurate data about the fiber's true characteristics.
