It can experiment at Voice, data and video signal synchronous measurement and display on BPON/EPON/GPON.

Providing simultaneous measurement for all three wavelengths on the fiber (1490nm, 1550nm,1310nm).

Used in Burst mode measurement of 1310nm upstream.

Use the software connect with PC, setting the threshold, data transfer, and calibration the wavelength.

USB communication port enables data transfer to a PC.1000measurement items can be saved in this PON power meter or computer for data review.

With optical power meter module, include 850、1300、1310、1490、1550、1625 six wavelengths

(SS-PPM-3123AP and SS-PPM-3123A without 850nm wavelength）；

With visual fault locator module（ Only SS-PPM-3123 and SS-PPM-3123AV）

Optical power meter and VFL with one port. （only SS-PPM-3123A）

Optional Chinese/English display.

Offers up to 10 different threshold sets in total, Three status LEDs represent different optical signal conditions of Pass, Warn and Fail respectively.

10 minutes Auto-off function can be activated or deactivated

Good key design, high sensitivity, greatly reducing the volume and weight of the tester.

Different models corresponding to different function, according to own use to choose.
