Buying Gain Equalization Filters

Top-level product category: icon optical components and devices

More general product categories: optical filters

Gain equalization filters are used to make the gain spectrum of an optical amplifier device flatter over a certain optical frequency range. These filters are essential for maintaining uniform signal amplification across multiple wavelengths in wavelength division multiplexing (WDM) telecom systems, ensuring consistent performance and signal integrity.

Making Good Purchase Decisions

As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.

NEW: Structured Decision Process

Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.

Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

1. Understand the technical background

It is important to sufficiently understand the technology before buying.

Use the comprehensive learning resources of RP Photonics:

If you need personal help, contact RP Photonics to get technical consultancy.

I feel that I sufficiently understand the technical background.

2. Define your requirements

It is essential to fully understand and clearly define your requirements before you buy.

We recommend that you develop a list of clear specifications according to your specific needs, against which you can later check the suitability of found product offers:

To help you, we have already listed some aspects we recommend you consider when buying gain equalization filters. Of course, there may be other aspects that are relevant to your specific case.

This list is for your own preparation, and can later (possibly in modified form) be used for quotation requests to suppliers.

I think that I am sufficiently informed about our requirements.

Otherwise, you will need to talk to your technical colleagues.

I consider the above list of specifications to be sufficiently complete, clear and accurate.

If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.

Insert these criteria when creating inquiry mails to suppliers with the buttons "Get quotation".

You find these buttons in the supplier list below or under "3. Find suitable suppliers".

3. Find suitable suppliers

We suggest three steps:

Below, you can find our list of suppliers for gain equalization filters. Use the checkboxes to mark possibly suitable suppliers.
The selected suppliers will appear below this list, along with your list of specifications. You can then indicate which specifications they meet according to your research. (You should finalize your specifications before doing this.)
Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

The Gain flattening filter (GFF), based on fiber Bragg grating technology, with model number OEGFF-100 is a reflective type filter. The OEGFF-100 can be used in C-band or L-band erbium doped fiber amplifier (EDFA) or Raman amplifier. One advantage of the OEGFF-100 compared with the thin film based GFF filter is that each filter shape is different due to customized fitting curve, and therefore no accumulated error when several of them are cascaded with each other. Advanced fiber Bragg grating fabrication technology and a patented temperature compensation package ensures the lowest ripple and smallest error function for the best gain equalization performance for your EDFA products.
