Introduce
The SR350 series optical time-domain reflectometer adopts a 3.5 inch color capacitive touch screen, which is easy to operate. It integrates eight functions, including OTDR, event map, stable light source, optical power meter, Visual light source, and lighting. Simple parameter settings and intelligent measurement make the operation more simple and efficient. The model is compact and lightweight, convenient to carry. The large capacity battery ensures an 8-hour extended measurement time and a 15-hour extended standby time, providing guarantee for field testing operations.
The SR350 series OTDR is mainly used to measure the length, loss, average loss, return loss, connection quality, etc. of various fiber optic cables. It has automatic optical protection function to prevent damage to the optical module. The model with a filter can support online testing, with a maximum online optical power of 0dBm. It can be widely used in the engineering construction, fault repair, fiber optic line maintenance, engineering acceptance, development and production of fiber optic communication systems, and other fields.
