SC Fiber optic reflector

The 1577nm SC Type Fiber optic reflector is an important device in the field of optical communication link detection.
The principle is the equivalent of a bandpass filter, which completely reflects light from
1,572 to 1,582 nm (more than 99.5%) while all other wavelengths pass through.

In the field of communication, the communication light
can be separated from the detection light, and the detection light can be prevented from passing through so as
to affect the communication signal. At the same time, the return light can be detected at the control end. Its
advantages are accurate control, stable work, long service life
