fiber optic circulator is mainly used to test the signal return in the system or network system. Through the return signal (mainly connecting the TX transmitting end to the receiving end of RX in pairs), it can detect various potential in the network link to achieve the test and evaluation of a single component or interface on the optical fiber network and the network, it is an ideal choice for testing the transmitted optical power and receiving sensitivity.

Feature:

Built-in LC loopback cable, support LC interface fiber optic module test

Equipped with a black protective shell to protect the optical fiber, which reduces the ring space and is easy to use

Each loopback module is equipped with two dust plugs to effectively prevent external pollution

Comply with RJ-45 end face design, low insertion loss, low back reflection and high alignment accuracy

Application:

Cabling system,ODF
