Feature: 

 1. Useful Tester: Used to evaluate FTTx, access construction and maintenance, can also identify optical fiber breakpoints, measure optical cable length, and calculate relative optical power loss.   

 2. Better Design: Comes with 3.97in touch screen to largely facilitate the operation, while the USB date interface enables easier further processing on data and analysis, very convenient and efficient.   

 3. Reliable Work: Supports up to 4 groups of wavelength of 1310/1550nm, 1310/1550nm, 1550nm and 1610nm, the OTDR meter ensures a long measurement range of 0-60km, very high in accuracy and reliability.   

 4. Practical Use: Allows for wide application in testing Ethernet cable distance, rj45 Ethernet cable sequence, LED light and so on, the optical tester will surely satisfy your various working needs.   

 5. Easy Carrying: Light in weight and compact in size as well, the optic fiber tester is very simple to carry for both indoor and outdoor works.
