SC Pigtail Type Reflector

1650nm Pigtail Type Reflector

Description

The fiber bragg grating reflector is a low-cost specific band reflector mounted on the optical network unit (ONU) side. It can reflect light pulses (1650 +/- 5 nm) from the OTDR on the fiber line terminal (OLT) side nearly 100%, while the working bands of the passive optical network (PON) are transmitted normally. The OTDR can determine whether the fiber line is normal by detecting the signal reflected by the fiber grating reflector. When the reflected signal is lower than the normal value, the line loss is too large; when the reflection value is 0, the optical fiber line is brokenTherefore, we can maintain the fiber line in time by the real-time monitoring of the fiber line.

Its performance indicators have an impact on communication lines, insertion loss affects the loss of optical fiber lines, and return loss affects the signal quality of communication lines. It is very important to select a filter with excellent indicators.
