OTDR 980EXT show error "there are light, test stop"

By FirstFiber Technologies October 22nd, 2024 261 views

I received 2 photos. One is OTDR testing with no cable, the other is connected to cable. Then test stopped with the message, means “ there are light, test stop”. Then the cable is not live cable.

The problem should be solved now. If not, contact our tech support team by email tech@firstfiber.cn

Note: if OTDR you bought is not with filter, please do not test active fiber.
