Introduction of Fiber Optic Coupler with its Benefits & Classification

A fiber optic coupler is an indispensable part of the world of electrical devices. Without these no signals would be transmitted or converted from inputs to outputs. This is the reason these are so important thereby this article discussed about these, introduction, classification and benefits in detail.

Fiber Optic Coupler is an optical cog that is capable of connecting single or multiple fiber ends in order to permit the broadcast of light waves in manifold paths. This optical device is also capable of coalescing two or more inputs into a single output while dividing a single input into two or more outputs. In comparison to a connector or a splice, the signals may be even more attenuated by FOC i.e. Fiber Optic Couplers; this is due to the division of input signal amongst the output ports.

Types of Fiber Optic Coupler

Fiber Optic Couplers are broadly classified into two, the active or passive devices. For the operation of active fiber coupler an external power source is required, conversely no power is needed when it comes to operate the passive fiber optic couplers.

Fiber Optic Couplers can be of different types for instance X couplers, PM Fiber Couplers, combiners, stars, splitters and trees etc. Let’s discuss the function of each of the type of the Fiber Optic Couplers:

Combiners: This type of Fiber Optic Coupler combines two signals and yields single output.

Splitters: These supply multiple (two) outputs by using the single optical signal. The splitters can be categorized into T couplers and Y couplers, with the former having an irregular power distribution and latter with equal power allocation.

Tree Couplers: The Tree couplers execute both the functions of combiners as well as splitters in just one device. This categorization is typically based upon the number of inputs and outputs ports. These are either single input with a multi-output or multi-input with a single output.

PM Coupler: This stands for Polarization Maintaining Fiber Coupler. It is a device which either coalesces the luminosity signals from two PM fibers into a one PM fiber, or splits the light rays from the input PM fiber into multiple output PM fibers. Its applications include PM fiber interferometers, signal monitoring in its systems, and also power sharing in polarization sensitive systems etc.

Star Coupler: The role of star coupler is to distribute power from the inputs to the outputs.

Benefits of Fiber Optical Couplers

There are several benefits of using fiber optic couplers. Such as:

  • Low excess loss,
  • High reliability,
  • High stability,
  • Dual operating window,
  • Low polarization dependent loss,
  • High directivity and Stumpy insertion loss.

The listed benefits of Fiber Optical Couplers make them ideal for many applications for instance community antenna networks, optical communication systems and fiber-to-home technology etc.

Optical Fiber In-line Polarizer & its Fine Features

The significance and value of Optical fibers don’t need any explanations or specifications in the world of electronics and technology. These devices are no doubt the tiny part but are equally important as well as requisite for the effective / efficient working of the machinery and electronic. When we talk about optical fiber In-line polarizer these are the cogs which can never be overlooked.

Optical Fiber In-line Polarizer

Low cost optical fiber In-line polarizer is the device to convert unpolarized light into linearly polarized light. It encompasses both, input as well as output as one input of single mode fiber and one output with polarization maintaining fiber. It can easily be connected conveniently into the optical systems through pigtailed input / output connectors.

Now let’s discuss the fine features of In-line Polarizer:

  • Low insertion loss: in telecommunications, the loss of signal power coming from the insertion of a device into the optical fiber is generally referred to as insertion cost. The insertion cost of the In-line polarization is stumpy and quite lesser than the other similar devices.
  • High extinction ratio: the polarizer especially, the In-line polarizer usually have the high extinction ratio i.e. the ratio of the two optical power levels of a digital signal produced by an ocular source.
  • High return loss: The optical fiber polarizer generates high return loss i.e. the loss of power in the signal reflected / returned by a discontinuity in a broadcast line or ocular fiber.
  • Compactness and light weight: Yet another beneficial feature of an In-line Polarizer is that it is quite compact as well as light weighted. This helps in the placement and execution of the appliance. Its light weight helps it work easily and effortlessly.
  • High stability and reliability: In-line polarizer is always recommended as it is quite stable as well as reliable. Unlike all other types of polarizers, the in-line polarizer has higher stability. This is the reason why companies and industries trust these.

 Beyond all, the optical fiber In-line polarizer is available in market at low costs. There are several organizations which offer and sell the high quality optical fiber solutions at competitive prices and ensure you an effective as well as a durable working.

So, whenever you seek the high quality optical fiber In-line Polarizer, or decide to buy them, make sure you choose a copper-bottomed company to get the best products and high quality services as well as high class solutions at competitive prices!
