MD7800 series high-performance OTDR adopts 7-inch color screen, which makes the operation easier. It intergrates 7 functions to help customers solve the communication link field test and later maintenance more effectively.

Product overview

MD7800 series high-performance OTDR adopts 7-inch color screen, which makes the operation easier. It intergrates 7 functions to help customers solve the communication link field test and later maintenance more effectively. The maximum dynamic range is 45dB. It can be penetrated through the light splliter to effecively improve the performance in PON network test.

MD7800 series are mainly used to measure the length, loss and connection quality of optical fiber and cabe. It is widely used in engineering construction, line maintenance test, emergency repair , development and production measurement of optical fiber and optical cable. It is mainly used in urban trunk line, backbone network and metropolitan area network.
