Handheld MINI FTTH PON OTDR Tester Optical Fiber Instrument For Engineer Test 
FTTH PON OTDR Decription
TWH-1625 FTTH PON OTDR Tester is used to carry out troubleshooting positioning and analysis for FTTH optical networks. It features the online test,test through splitter up to 64 splitters deployed at one tier or two tiers and OPM+VFL functions.
TWH-1625 is a sort of pro-tool-type and ultrahigh performance-price ratio PON OTDR. It can make faults locating and analysis in the FTTH PON network and FTTX network, featuring OTDR’s online test function and finding faults by passing splitters. As well, it features convenient and fast as well as reliable performance in the optic network installation and operation/maintenance to the effect of reducing cost and enhancing the efficiency of operation/maintenance in terms of projects. Excellent repeatability, less complex settings, one-key operation, and integrating VFL and OPM functions are all countable.
