Buying Fiber-optic Attenuators

Top-level product category: icon fiber optics

More general product categories: optical attenuators

Related product category: fiber optics

Fiber-optic attenuators are used to reduce the optical power propagating in a fiber. Available with various fiber connectors, they can be used to prevent excessive signal power from reaching photodetectors and other sensitive components, thus protecting them and ensuring accurate signal processing.

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.

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 fiber-optic attenuators. 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.

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

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

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 fiber-optic attenuators. 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.

fiber-optic attenuators

The laser attenuator 48AT-0 is used for reproducible and precise reduction of the power output by the laser. The collimated laser beam is constricted by a precision ball transported by a scaled micrometer screw. The subsequent single-mode fiber coupling is used as a mode filter.
