OTDR Launch Cable Box OM3 Disc Extension Cord 300/500M Extension Cable SC/FC/LC/ST UPC Connector

Products Description
Designed to aid in the testing of fiber optic cable when using an OTDR. The OTDR Launch Box is used with Optical Time Domain Reflectometers (OTDR's) to help minimize the effects of the OTDR's launch pulse on measurement uncertainty. Available in many different configurations and fiber lengths.0.5km 1km 2km MM OTDR Test Extension Line Fiber Optic OTDR Launch Cable Box.
Feature
1. Pulse Suppressor, Launch Box, Delay Line, Installation/Testing, Training, Calibration

2. Compound Latch for positive seal and easy opening with locking feature.

3. Non­metal construction will not dent, corrode, or conduce electricity

4. Water and dust prove allowing the unit to be taken into almost any environment

5. Case can house up to 2,000 meters of fiber

6. Auto Purge Valve for changes in altitude and temperature
Application
Effect of blind spots on OTDR measurement accuracy we refer to a series of "blind spots" caused by saturation of OTDR receiver caused by reflection from feature points such as active connectors and mechanical joints as blind spots.The blind area in theoptical fiber can be divided into event blind area and attenuation blind area: the length distance between the starting point of the reflection peak and the saturation peak of the receiver caused by the interference of the active connector is called eventblind area;The distance between the starting point of the reflection peak and the point at which other events can be identifieddue to the interference of active connectors in the optical fiber is called the attenuation blind area.For OTDR, the smaller theblind spot, the better.The blind area will increase with the increase of the width of the pulse width. Although the increase of the pulse width increases the measurement length, it also increases the blind area of themeasurement. Therefore, when we test the optical fiber, we need to use narrow pulses to measure the optical fiber attached to OTDR and the adjacent event points, while we need to use wide pulses to measure the remote end of the optical fiber.
