OM4 100G OTDR Launch Cable Box Test Tool ST/UPC to ST/UPC 1000m/6561.68ft | Multimode, 50/125m, OTDR Dead Zone CCompensation, Portable Storage Box, For Data Center Fiber testing

This NWANSI OM4 OTDR fiber optic cable test box is recommended for data center technicians, high-speed fiber cabling contractors, and cloud infrastructure engineers. It addresses the critical pain point of inaccurate near-end test readings in 40G/100G high-speed multimode links, avoiding costly acceptance errors and troubleshooting delays. This cable is specifically designed for laser-optimized OM4 50/125m multimode networks and can be used for testing 40G and 100G high-bandwidth fiber backbones. When used with an optical time domain reflectometer (OTDR), it compensates for the dead zone of the OTDR's emitted pulses, significantly improving the measurement accuracy of near-end connectors, splices, and patch panels in high-speed OM4 links.

It uses high-quality OM4 laser-optimized fiber with ultra-low attenuation, adding virtually no additional loss during testing, thus ensuring the authenticity and repeatability of test data. This product is available in five lengths: 150 meters, 300 meters, 500 meters, 1000 meters, and 2000 meters, to meet various blind spot compensation needs, such as short patch cord testing and long-distance backbone network fault location. Four UPC polished connectors are availableLC, SC, FC, and STensuring broad compatibility with virtually all mainstream OTDR instruments and OM4 cabling infrastructures. No additional adapter patch cords are required, enabling plug-and-play functionality, thus reducing setup time and improving field testing efficiency. The entire assembly is encased in a robust, shockproof protective case with a custom-designed internal fixing structure. This case provides effective protection for fiber optic cables during transport between data centers, server rooms, and construction sites. Its compact and lightweight design allows it to easily fit into a technician's toolkit for convenient routine inspections and emergency troubleshooting. This is a professional-grade testing accessory and an essential tool for commissioning and maintaining OM4 high-speed networks. All products are brand new and manufactured under strict quality control. Due to manual measurement, there will be a length error of 1% to 5%, which will not affect normal test performance.
