Palm OTDR: FiberPal OT-8600

Palm OTDR: FiberPal OT-8600


The Palm OTDR (OT-8600) is a new miniature, high performance optical time domain reflectometer which is designed as fiber troubleshooter for locating fiber connector, break and imperfections for access networks. It detects event locations along the optical fiber and displays the results on a color LCD display. This Palm OTDR is light, reliable and easy to use, hence it is ideal for FTTX testing.


The Application Software equipped is used for data analysis, processing and storage. With the USB Interface port, enabling OT-8600 to transfer test data to computer easily.

Ordering Information for OT-86XY


Wavelength (X)

                 Measurement Range (Y)

1 = 1310 nm 

2 = 1550 nm 

3 = 1310 / 1550 nm

6 = 1625 nm

0 = 20 km

6 = 30 km


Example of Ordering statement: OT-86XY 

e.g. : OT-8636 = One of OT-8600 series products with wavelength of dual bands of 1310nm and 1550 nm and measurement range of 32km. (The number of blue color is optional based on customers needs. Please refer to details of the Ordering Information above)
