Product Description

Highly reflective device Optical Grating Filter Fiber Bragg Grating Filter FBG Reflector 1650nm SC/APC

The FBG reflector is a standard SC type connector structure, which package a special FBG in the ceramic ferrule.

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 broken.Therefore, we can maintain the fiber line in time by
the real-time monitoring of the fiber line.

Application:
Detection and maintenance of Passive Optical Network lines (applied to FTTx).

Optotec 1650nm Reflector is based on Fiber Bragg Gratings  (FBG) technology to reflect optical signal of 1645nm to  1655nm (optical line monitoring signal).
A FBG filter is a type of distributed Bragg reflector  constructed in a short segment of optical fiber that reflects
particular wavelengths of light and transmits all others.
This is achieved by creating a periodic variation in the  refractive index of the fiber core, which generates a
wavelength-specific dielectric miror.
Comparing with the traditional reflector with thin film  technology, FBG reflector has the advantage of very high
reflectance at the test signal, very low insertion loss at the  traffc signal very sharp reflection bandwidth edge, and very  long lifetime.
A FBG can therefore be used as a high performances inline  optical filter to block certain wavelengths, or as a
wavelength-specific reflector.
It pass the communication without disturbing and provide a  high reflectance for the monitoring signal at the termination  of a passive optical network (xPON).
Packaged in SC/APC bulk-head attenuator style for install  easily. Pigtail package style available upon request.
