FTTX Fiber Optic Transceivers Optical SC/APC Fiber Optic wdm Reflector

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.

Function

Pass 1310+1550 nm and Stop 1650nm.

RoHS compliance

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.
