Wit780 Datasheet

The wit780 series optical fiber line tester is a portable, full-function, economical OTDR, optical time domain reflectometer.

He was born in the context of the global wide application of optical fiber and cable, aiming at the optical fiber communication system wiring, construction, testing, maintenance, overhaul, FTTH fiber to home project, etc.

This product is mainly used to measure the length, loss, connection quality and other parameters of all kinds of optical fiber and optical cable; it can quickly locate the event point and fault point in the optical fiber link accurately.

The appearance of wit780 conforms to the principles of ergonomics and is firm and durable.

It has a simple and friendly operation interface, dual operation mode, which simplifies the use of users.

One button scanning, fast test results;

Event related information includes: event number, event location (distance), loss, reflection, slope between event points (attenuation coefficient), cumulative loss;

The whole machine adopts intelligent power management mode, large capacity lithium battery makes the whole machine work for more than 10 hours.
