Communication Filter

Multi – layer thin films and special film filters are used to separate and combine various wavelengths of light in fiber optic network systems.

Usage : NBPF, BBPF, GFF, LWPF, EDGE, filter for CATV, FTTx etc.

Single Crystal/Fiber AR

Long Wavelength Pass Filter【LWPF】

Pass Band Width Range : 1570~1700nm
Pass Band Ripple ≦0.15dB
Peak Loss ≦0.2dB
Reflectance Band Width Range : 1400~1550nm
Reflectance Band Isolation ≧30dB

Very sharp transition characteristic.
We can process from board thickness of 0.1mm.
