Q1: Does the OTDR (FF-980PRO) support both 1310nm and 1550nm wavelength to test fibers?
A1: Yes, the OTDR support both 1310nm and 1550nm wavelengths. You can switch these two wavelengths on parameter setting easily.

A2: Yes, the OTDR support both read time and average time testing mode.

Q3: Does the test result can be displayed quickly on screen?

A3: Yes, very quickly. If you selected "Auto" testing mode, it takes 3 to 5 seconds to display OTDR curves and event list on screen. When testing mode stays in "manual" mode, you can set the average time to 15 seconds, 30 seconds, etc...

Q4: What connectors do come with the OTDR?

A4: The OTDR comes with FC, SC and ST connectors in default. LC connector is sold separately.

Q5: My fiber cable is with a APC connector, but I have bought an OTDR with UPC connector(port). How can I make the test?

A5: According to industrial standard, APC connector can not work together with UPC connectors. So (1) please find a short fiber patch cord, one end is with APC and the other end is with UPC. (2) Use the UPC to APC adapter. See the picture. (3) buy an OTDR with APC connector(port). Please let our sales know you are going to buy an OTDR with APC connector before you place your order.

Q6: Do I need to add money for extra functions (VFL, OPM, OLS, Touch Screen) ?

A6: No. The OTDR comes with all of these functions.

Q7: Do the OPM and OLS function can turn on same time?

A7: No, When you turn on OLS, OPM turns off automatically.  And when you turn on OPM, OLS will turn off automatically.  That means the device itself can NOT test its laser value.
