How to Choose a Coupler Used for Maintaining Polarization

Coupler is a vital element used with electronic devices. For example telephone coupler which is used to allow you to connect both a telephone and a fax machine to the same telephone line. CATV couplers are used with TV and let you connect several TV sets to a single cable from Comcast. And the tap coupler one of the most popular couplers used for a wide range of applications including fiber sensors.

Optic couplers such as tap couplers work more like the electronic couplers. They are used to split the signal to multiple points (devices), and so they are needed for tapping (monitoring the signal quality).   Tap couplers can also be used for more complex telecommunication systems which require more than simple point-to-point connections, such as ring architectures, bus architectures and star architectures.

There are different types tab couplers and each has some certain functions to perform. For example, 1064nm Polarization Maintaining Tap Coupler, a widely used polarization maintaining coupler which splits the light from the input PM fiber into two output PM fibers. This works whether you need to align the state of polarization either with the slow axis or fast axis of the PM fibers. Made of fine grade rugged stainless steel, the coupler is durable and can deliver the high performance. In addition, the device also provides a lot of other benefits such as low excess insertion loss, low back reflection, and high extinction ratio.

Made of separate light crystals, the tab coupler has output port of light which is different from that of the PM filter coupler.  The best thing about this device is that its coupling ratio is more accurate than most other couplers. And also it can handle higher power.

This coupler is designed to split the high power linear polarized light into various paths and all that without perturbing the line. You can also use tab coupler to monitor the signal power in a PM fiber system.

Given a number of benefits, the coupler is used for a wide range of applications including interferometers, power sharing in polarization sensitive systems, and signal monitoring in PM fiber systems.

Likewise, each coupler performs some certain functions, and so they can be suitable for some specific purpose. When you are looking for couplers, you should get deep into details and know about everything right from features and how do they work to their benefits and where they can be best used. This will help you can choose couplers right for you.

What types of coupler you buy, make sure you buy from a reputed source that has been in the field for a long spell of time. These are the top sources to buy Polarization Maintaining Tap Couplers or any other type of couplers for the price most competitive in the market.
