OP480-OP280 MTP/MPO and Ribbon Fiber Polarity Test System

Advancing the World of Fiber Optics™

OP480 OP280 1

OptoTest’s OP480MT MultiFiber Polarity Tester automates testing for broken and crossed fibers with immediate and easy-to-read results. When used in conjunction with the OP280MT Ribbon Visual Fault Locator, the OP480MT quickly  displays results for many different ribbon configurations and channel counts including type A, B, C, and Universal.  Additionally, it can be configured with a user-defined custom mapping via utility software.

Since it uses a non-contact method of testing, the OP480MT reduces the number of times a cable must be connected during production.  With fast testing time and customizable configurations, it can greatly reduce major bottlenecks in the production process. Once connected, polarity and continuity are identified almost instantaneously.

The OP480MT and OP280MT are available individually or as part of a kit—the OP-POLARITYKIT-12—which will include the OP480MT, OP280MT, launch and receive optical cables for male and female, mating adapters, cleaning tools, software, portable power pack in a carrying case.
