OTDR: locate the faults and breaks of an optical fiber, measure the length, the transmission loss, and the splice loss, ETC, (30km for attenuation & 50km for breaking point)

LTDR: measure the length, breaking point, short-circuit point, impedance mismatch point and distance between 2 points for network cables, coaxial cables, and other cables & wires.

OPM: measure the average optical power.

PON power meter: measure the PON upstream signal (1310nm & 1277nm) power, to judge whether the on-line ONU exist and ONU upstream pulse is in normal condition.

VFL: used for fiber tracking, fiber routing and continuous checking in the optical network.

Network test: with the integrated Ethernet interface chip. It is used to test various network features including ping and connectivity tests like – PPPOE dial, DHCP test, ARP test, web test and so on. To determine the network faults.

Internet speed test: measure the network download speed and website response/delay speed.

Line test: measure the loop resistance and unbalance resistance of network cables (cat5, caqt5e/ cat6/ cat7), and the loop resistance of the coaxial cable, other cables & wires, to judge the faults condition of all physical connections.

Line search: search the specified cables & wires by sending and receiving signals (audio & ultra-audio).
