Product Name:

Optical Grating Reflector

Product Details

Description And Application:

1650nm fiber grating optical filter is the important components in the field of Optical communications link to detect. The principle is equivalent to a band-pass filter, which completely reflects light from 1643.5nm to 1656.5nm back (the return ratio is over 99.5%) and all other wavelengths of light pass through. Used in the field of communication can be separated communication light (C + L band) and detection of light, to prevent the detection of light through to the communication signal impaction, and can detect the return light at the control. All aspects of fiber grating indicators are stronger than the coating method.

Features:

grating embedded in the fiber, free from environmental pollution;

high reliability, long life expectancy

Reflectance is high for bands that need to be blocked (above 99.5%), close to total reflection

The wavelength of the reflection band is controlled accurately (1643.5nm ~ 1656.5nm)

In the bandpass edge of the transition zone is very narrow (less than 2nm), this area is all-pass;

Using the standard common adapter structure, easy connection;


Product Parameters:


Note:

(1) ORL(dB) = -10 log 10(Reflected Power/ Input Power) [dB];

(2) IL(dB) = -10 log 10(Output Power/ Input Power) [dB];

(3) To measure the Return Loss of reflect band, the light of 1650nm should be injected from the female side of reflector.


Operating temperature/moisture/storage:
