1310nm 1550nm Polarization Maintaining Filter Coupler

The GK-PMTC Series Polarization Maintaining Tap Coupler from GKER Photonics is designed to provide exceptional
performance in optical signal distribution and monitoring. Utilizing advanced manufacturing techniques, this coupler
ensures precise splitting of optical signals while maintaining high polarization stability. It features high extinction ratios
and supports a range of tap ratios, including 1%, 2%, 4%, 5%, 10%, 20%, and 50%. The coupler is engineered to offer
minimal excess loss and uniformity, with a maximum excess loss of 0.7 dB for 1 × 2 configurations and 1.0 dB for 2 × 2 configurations.
The GK-PMTC Series is suitable for use in demanding optical communication systems, including fiber lasers and high-performance networks. It operates effectively across a wide wavelength range of 1310 nm and 1550 nm, with a center
wavelength tolerance of ± 40 nm. Built to endure harsh conditions, it withstands up to 300 mW of continuous optical
power and operates within a temperature range of -5°C to +70°C, while being able to withstand storage temperatures
from -40°C to +85°C.
