In today’s technologically advanced world of electronics, there is no need to explain the significance and value of optical fibers. There is no denying the fact that these devices are quite a tiny part of the system but they are just as important as well as requisite for the effective functioning of the electronics and machinery.

In this blog, we will specifically take a look at what an optical fiber in-line polarizer is and dive into the fine features it offers.

What is an in-line polarizer?

An in-line polarizer is a low-cost optical fiber that is used to convert unpolarized light into linearly polarized light, which it does quite efficiently. This tends to encompass output as well as input as a single input of single-mode fiber and a single output with polarization maintaining fiber. Moreover, it is quite easy and convenient to connect it into optical systems with the help of pigtailed input or output connectors.

In-Line Polarizer

Now that we know what an in-line polarizer is, let’s take a look at some of the fine features that make it so useful and effective.

  • High extinction ratio:
    Most of the polarizers, especially the in-line polarizer, tend to have quite a high extinction ratio, which means that the ratio of the two optical power levels of a digital signal is produced by an ocular source.
  • Compactness and lightweight:
    Another one of the beneficial features of an in-line polarizer is that it is not only compact but quite light-weighted as well. This specific characteristic of the polarizer helps in the placement and execution of the appliance effectively. Since it is not heavy, it makes the process all the more easy and effortless.
  • Low insertion loss:
    In telecommunication terms, the loss of signal power that comes from the insertion of a device into the optical fiber is known to be the insertion cost. When it comes to the insertion cost in an in-line polarizer, it is known to be quite stumpy and much lesser as compared to other similar devices.
  • High return loss:
    The optical fiber in-line polarizer     tends to generate high return loss, which is the loss of power in the signal reflected by a discontinuity in a broadcast line.
  • Reliability and high stability:
    High stability and reliability are some other beneficial features that in-line polarizer tends to possess. Unlike most of the other types of polarizers, since the in-line polarizer provides higher stability, more and more companies are starting to trust them.

Apart from all of these features that are mentioned above, another thing that makes it a more preferred option is that in-line polarizers are available at low costs in the market. However, you must make sure that you find a reliable and highly reputed supplier to buy a high-quality optical fiber in-line polarizer.
