It can perform in-service testing of all PON signals (1310/1490/1550nm) on any spot of the network. Pass/fail analysis is conveniently realized through users’ adjustable threshold of every wavelength. Adopting 32 digits CPU with low power consumption, DW-16805 becomes more powerful and rapid. More convenient measurement owes to friendly operation interface. Key Features 1) Test 3 wavelengths’ power of PON system synchronously: 1490nm, 1550nm, 1310nm 2) Suitable for all PON network (APON, BPON, GPON, EPON) 3) User-defined Threshold Sets 4) Supply 3 groups of threshold values; analyze and display pass/fail status 5) Relative value (differential loss) 6) Save and upload the records to computer 7) Set threshold value, upload data, and calibrate wavelength through management software 8) 32 digits CPU, easy to operate, simple and convenient 9) Auto power off, auto backlight off, low voltage power off 10) Cost efficient palm size designed for field and lab testing 11) Easy-to-use interface with large display for easy visibility Main functions 1) 3 wavelengths’ power of PON system synchronously: 1490nm, 1550nm, 1310nm 2) Test the burst mode signal of 1310nm 3) Threshold value setting function 4) Data storage function 5) Auto backlight off function 6) Display the voltage of battery 7) Power off automatically when it is in low voltage 8) Real-time clock display Specifications
