1577nm FBG Reflector SC Type
Product Description and Application:
The 1577nm Fiber Bragg Grating (FBG) Filter is an essential component in the optical communication field for link detection. It functions similarly to a band-pass filter, completely reflecting light within the 1572nm to 1582nm range (with a reflection ratio exceeding 99.5%), while allowing all other wavelengths to pass through. In communication applications, this filter can separate communication signals from detection signals, preventing detection light from interfering with the communication signal, while allowing the control end to detect the reflected light. Its advantages include precise control, stable operation, and long service life.
Product Functions:
Pass 1310+1550 nm and Stop 1577nm.
RoHS compliance

Note:
ORL(dB) = -10 log 10(Reflected Power/ Input Power) [dB];
IL(dB) = -10 log 10(Output Power/ Input Power) [dB];
To measure the Return Loss of reflect band, the light of 1650nm should be injected from the female side of reflector.

5：Structure
Product Features:
Embedded within the fiber, the grating is unaffected by environmental contamination.
High reliability and long lifespan.
High reflectivity for the targeted wavelength band (exceeding 99.5%), approaching full reflection.
Precise control over the wavelength range of the reflection band (1572nm to 1582nm).
Narrow transition region at the edge of the passband (less than 2nm), transitioning to full transmission beyond this region.
Utilizes a standard, universally adaptable adapter structure for easy plug-and-play integration.
