Product Description

Polarization Maintaining Filter Wavelength Division Multiplexer

(GK-PMFWDM Series)

Description

The GK-PMFWDM Series by GKER Photonics offers advanced wavelength division multiplexing while maintaining signal polarization, making it an excellent choice for high-speed WDM network systems. Utilizing environmentally stable thin-film filter technology, these devices deliver superior performance in managing multiple wavelength signals with precise polarization control.

This series is characterized by its high extinction ratio, low insertion loss, and high return loss, ensuring minimal signal degradation and optimal performance in demanding applications. The GK-PMFWDM Series supports a wide wavelength range from 1270 to 1350 nm, 1450 to 1490 nm, and 1530 to 1600 nm, with typical insertion losses as low as 0.4 dB and maximum insertion losses up to 0.7 dB. The device offers excellent isolation with a minimum of 25 dB, effectively reducing crosstalk between channels.

Key features include a minimum extinction ratio of 20 dB and a high return loss of up to 50 dB, which enhances signal clarity and system reliability. The filters are designed to handle up to 300 mW of continuous wave optical power and exhibit impressive thermal stability, operating reliably within a temperature range of -5°C to +70°C and withstanding storage temperatures from -40°C to +85°C.

The GK-PMFWDM Series is ideal for high-speed WDM networks, offering robust performance and durability in various environmental conditions.
