OTDR, OTDR test, Optical Time Domain Reflectometer
SW100 Multi-functional OTDR is a reliable tester for measuring the optical fibers. Integrated OTDR, Light source, Power meter, VFL, RJ45 cable sequencing & cable length, etc., to meet the testing needs of different occasions. It can be used to measure the length, loss, splice quality assessment and other parameters of various fiber opticcables, and is widely used in the line laying, maintenance and repair of fiber- to-the-home, metropolitan area network and secondary backbone network communi- cation system.

Ultra-Portable & Pocket-Sized (Proof of Concept): Weighs only 0.9kg and measures just 185 x 116 x 45 mm, making it perfectly suited for climbing and single-handed field operation.
7-in-1 Essential Toolkit: Combines OTDR, Event Map, OPM, VFL, Light Source, Fiber Loss Test, and RJ45 Cable Test in one compact unit.
Safe Live Fiber Monitoring: Optional 1625nm filtered port allows for safe, non-intrusive troubleshooting on active PON lines.
RJ45 Cable Test Mastery: Supports Wire Sequence Test (Straight/Crossover) and crucial Cable Length Measurement for comprehensive network verification.
Easy Maintenance: Features a detachable universal connector for simplified cleaning and maximum instrument longevity.
Extended Endurance: High-capacity Li-ion battery supports over 10 hours of continuous field operation.
