Gain Flattening Filter for Optical Amplifiers

Gain flattening filters (GFF) are used in design high performance optical amplifiers or ASE light sources that offer flat gain spectra or flat output light spectra.

We provide fiber Bragg grating (FBG) based gain flattening filters for Erbium doped fiber amplifiers (EDFA), EDF based ASE light sources, Raman amplifiers or other fiber optical amplifers.

We can customize this product to best match the requirement for customer's system or optical link design.

Features:

• High reliability
• Rapid design and production
• Minimum error function to match the required spectrum
• Telcordia 1209 and 1221 compliance
• Low cost

Applications:

• Optical fiber amplifiers or broadband light sources
