MAY630 PON OTDR is a new generation of portable and intelligent measuring instrument for testing fiber optic communication system. It adopts 7 inch capacitive touch screen and integrates NINE major functional modules, which help customers effectively solve the field testing and maintenance.

It is mainly used to measure the length, loss and connection quality of optical fibers and cables, and can be widely used in engineering construction, network maintenance and testing, emergency repair, and the development and production of optical fibers and cables.
The highest 45dB dynamic range can penetrate optical splitters easily for PON network testing.
The design concept of multi-functional integration, precision testing and convenient operation makes the field testing simple.

4. Optical Power Meter (OPM)
5. Visual Fault Locator (VFL)
Visual Fault Locator uses red laser of 650nm to locate broken fiber point and test fiber continuity.
6. Insertion Loss
OPM and OLS can be opened at the same time to test insertion loss.
7. Fiber Inspection
Fiber Inspection is used to check fiber optic connector endface. The inspection probe is sold seperately.
8. Ethernet Tools
It supports PING, PPPOE, and IP Scan.
9. Remote Test
Computer connects with OTDR via Ethernet and the software in the computer realizes remote control such as parameter distribution, start-up test and graphic display.
10. Report Print
PC software helps print out OTDR test reports. It supports files batch processing.
