SW100 Multi-functional OTDR

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.
