Optical Communication Filter

| Gain Flattening Filters 

| Dense Wavelength Division Filters（DWDM）

| Dual Pass Band Filters | Extremely Narrow Band Filters

Our Advantage--Advanced Coating Technology in the world

Gain Flattening Filter(GFF) is usually used in conjunction with EDFA to ensure thatthe amplification communication channels all have the same signal gain. GFFs are characterized by "Peak to Peak Error Function" (PPEF), which measures how close the spectral properties of the GFF are to the desired target curve. The custom-built GFF is designed to handle the most challenging parameter requirements.

Our unique design and coating technology allow us to go beyond the traditional gain flat filter GFF to cover hundreds of different target curves that have emerged over the past two decades, from simple parabolic shapes to very difficult shapes with high modulation depths and steep slopes.In addition, xxx's GFF design also provides a GFF that can be attached with functions similar to a bandpass filter. For example, the GFF can be used to block the pumped laser source, eliminating the need for additional filters for optical amplifiers.
