1 Typical, backlight off, sweeping halted at 25 degree, 12 hours typical continuous testing.
2 Model T40F/T43F/T45F are integrated with optical filter, which allow them to test PON network online (by using 1625nm wavelength) and will not interrupt the fiber signal.
3 Dynamic range is measured with maximum pulse width, averaging time is 3 minutes, SNR=1; The level difference between the RMS noise level and the level where near end back-scattering occurs.

4 Event dead zone is measured with pulse width of 3ns; attenuation dead zone is measured with pulse width of 5ns.

5 1310/1550nm laser source uses OTDR1 port, and 1625nm or 850/1300nm uses OTDR2 port.
