Description
Overview
GAOTek tdr has 2.4 mi (4 km) OPM VFL 4.97 mi (8 km) optional large battery capacity is a multi-functional hand-held VDSL2 test instrument with small size, specially designed for xDSL line test (xDSL include ADSL, ADSL2, ADSL2+, READSL, VDSL2 etc.) and maintenance. It provides xDSL test, PPPoE dial test, DMM test, Modem emulation, line voltage indication and so on. The tester has LCD display and menu operation, which can display the test results directly and improve the xDSL broadband service greatly. It’s the best choice for field operators for installation and maintenance.
