Polarization Maintaining Tap Coupler: Features & Major Applications

 The polarization maintaining (PM) tap coupler basically provides optical signal splitting with tap ratio while also preserving the exact state of polarization. By combining the PM collimators and thin-film filter technology, the polarization maintaining coupler features high return loss, low insertion loss, environmental stability, and high extinction ratio.

 

The PM tap coupler splits the light coming from the input PM fiber into two outputs PM fibers. The polarization state further can be aligned with the fast axis or the slow axis of the polarization maintaining fibers. The stainless steel and rugged tap coupler are mainly designed for stability as well as high optical performance. The device with split ratios from 1 to 50% is now available so you can utilize it accordingly to your needs.

 

Some major applications of polarization maintaining tap coupler:

 

There are various applications of PM tap coupler, among which the major ones include:

 

Monitoring signal in polarization maintaining fiber systems

Fiber sensors

Helps in power-sharing of polarization-sensitive devices and systems

Polarization maintaining interferometers

Fiber optic devices and instruments

Coherent detection

Polarization maintaining tap couplers are made of separate crystals of lights and the output port of lights emitted is different from the polarization filter coupler. The coupling ratio is more accurate, while it can also handle high power as compared to the PM filter couplers.

 

On the other hand, the PM couplers can also be used to split high power linearly polarized light into different paths and that too without disturbing the state of polarization (SOP). Furthermore, it can even be used as a power tap for monitoring the signal power in the PM fiber system that functions without perturbing the linear state of polarization (SOP) of light in the polarization maintaining fiber.

So, these are a few primary features and applications of polarization maintaining tap couplers that you must be aware of. Besides, if you have the requirement of this device or any other type of PM coupler with tailored specifications then you may simply talk to PM coupler manufacturers and get the best assistance for the same. Just be sure to consult the right manufacturer so you can be confident that you are investing your money and time on the right device and at the right place.

Common Armored Fiber Optic Cables

  Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables exist: interlocking and corrugated. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection.   The Structure of an Armored Fiber Optic Cable In basic armored fiber cable designs, the outer sleeve provides protection against wind, solvents, and abrasion. This outer sleeve is usually made of plastic such as polyethylene. The next layer between the sleeve and the inner jacket is an armoring layer of materials that are difficult to cut, chew, or bu

what the Differences Between FBT Splitter and PLC Splitter

  In FTTx and PON architectures, optical splitter plays an increasingly significant role to create a variety of point-to-multipoint fiber optic networks. But do you know what is a fiber optic splitter? In fact, a fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. Basically, there are two types of fiber splitter classified by their working principle: fused biconical taper splitter (FBT splitter) and planar lightwave circuit splitter (PLC splitter). You may have one question: what’s the difference between them and shall we use FBT or PLC splitter?   What Is FBT Splitter? FBT splitter is based on a traditional technology to weld several fiber together from side of the fiber. Fibers are aligned by heating for a specific location and length. Because the fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. And then a stainless steel tube covers the inner glass tu

Introduction of Optical Fiber Couplers and How Do They Work?

 What are optical fiber couplers? A fiber optic coupler can be defined as an optical component used with one or more input fibers and several output fibers in fiber optic systems. A coupler essentially puts two or more cores of fibers together to connect. The simple coupler is the fused fiber 2x2 coupler. Couplers are used as multiplexers that are resistant to certain wavelengths. A fiber output depends on the wavelength of light and the frequency of polarization. The fiber refractive index also plays a significant role in the performance. Let’s checkout how do optic couplers work to understand this better. How do fiber optic couplers work? Either fiber optic couplers separate optical signals into multiple paths or combine multiple signals in one direction. Optical signals are more complicated than electrical signals, making it more difficult to design optical couplers than their electrical copy. Unlike electrical currents, the optical signal consists of a stream of signal carriers, in
