Coligh Telecommunication Filters for Optical Fiber Industry

Wavelength Division Multiplexing (WDM) Systems
CWDM/DWDM/LWDM/MWDM telecome filters are used for multiplexing and demultiplexing wavelengths at different intervals, combining optical signals of different wavelengths into a single optical fiber for transmission.

5G Front-Haul Networks
Using LWDM and MWDM can reduce the cost of 5G optical modules, improve bandwidth utilization, and support optical fiber transmission between 5G base stations.

Optical Amplifiers (EDFA)
GFF filters are used to equalize amplifier gain, ensure flat gain output, and reduce signal amplification distortion.

Optical Transmission Equipment
Bandpass filters and cutoff filters can be used in devices such as wavelength splitters, combiners, and optical isolators within optical fiber transmission systems to ensure high-quality optical signal transmission.
