What’s the Need for Installing CWDM Mux/Demux

An abbreviated form of Coarse Wavelength Division Multiplexing, CWDM technology is a great way of creating a flexible “pay-as-you-grow” type of high capacity optical network. This technology is widely used in dual fiber applications. Once you get CWDM Mux/Demux module installed in your network, you can benefit from the added capacity without ever having to interrupt or break the existing traffic. 

The Mux/Demux Module

A Mux/Demux module is made of a multiplexing unit that has the capacity of combining all eight wavelengths into a single mode fiber strand and a demultiplexing unit that has the capacity of splitting the incoming light into eight different data channels. This device gives up to 16-channel and even 18-channel multiplexing on a single fiber. A standard CWDM Mux/Demux bundle sort consists of ABS box bundle, LGX package, and 19” 1U rackmount.  

Counted under the category of WDM, the main goal of using such a device is to add the extra capacity to network and to meet a wide range of necessities and system arrangements. There are various board applications that require channel CWDM including Gigabit and 10G Ethernet, Fiber Channel, ATM, ESCON, SDH/SONET and CATV.  

Since CWDM items are usually epoxy-free on the optical side, this provides better working conditions. Besides, in CWDM Mux/Demux, there is a high level of channel segregation which prompts better outcomes. 

CWDM Mux/Demux Uses

WDM and Access Systems: Since these channel sorts are a part of WDM class, their best application is in the WDM and access systems. 

Line Checking: Such devices also find their application as a line observer/checker. Line checking helps in ensuring that there is no crash in the similar line of another range or frequency. 

Cellular Applications: The arrangements of CWDM channels have their use and application in the Cellular area as an unparalleled panacea for various problems. 

Telecommunications: The broadcast communication area has a wide usage of CWDM arrangements at an incredible rate. CWDM technology is a perfect solution for straightforward transmission of signals. 

Apart from these applications and elements, the CWDM technology is also used to uncover the deficiency of fiber and straightforward transmission of exchange while reducing the charges of system building. This is the reason why Channel CWDM Mux/Demux modules have a significant place in the realm of fiber optics, flag transmission, multiplexing and so on.

All About High Power Isolators!!

Power isolators can be defined as one type of mechanical switch that is used to isolate a fraction of the electrical circuit when needed. High power isolator switches are mainly used for opening an electrical circuit in the condition where it is no-load and is not to be opened while current flows through the line. 

Generally, high power isolators are placed on the circuit breaker at both the ends, and thus circuit breaker repair works can be done easily that too without any risk. On the other hand, 1064nm High Power Isolators can be used in substations so as to allow isolation of tools such as transformers, circuit breakers, etc.

This kind of power isolation is furthermore needed in a number of instances including:

  • To prevent ground loops in various communication networks
  • To protect different industrial operators from high voltage problems
  • To enhance noise immunity in various operations
  • To protect costly processors and circuits from high voltage
  • To communicate with high side devices and tools in a power converter system

How do power isolators work?

The working of a power isolator is not that challenging and can be easily functioned in different ways including manual, semi-automatic, and fully automatic. Sometimes, they can also be used as switches that are closed and opened depending on the needs and demands of the operation. Plus, they are also used in a fixed position to keep the isolation in electrical transmission lines, grid stations, and transformers. 

What are the different types of power isolators?

Typically, power isolators can be divided into three types, namely:

  • Double break type isolator- this type of isolator has major loads of post insulators where the middle one has a flat male contact or a tubular that is turned straight by a short spin.
  • Single break type isolator- in this type of isolator, the contact is separated into two elements, the female as well as male contact.
  • Pantograph type isolator- this type of high power isolator allows for a current switchgear installation, and includes an operating and post insulator. 

What is the major purpose of using high power isolators?

The main purpose of high power isolators is to isolate one part of the circuit from the other. They are generally put on both the ends of the circuit breaker in a sequence that they make the replacement or repair of the circuit very easy and without any danger. It is not intended to be opened when current is flowing in the line.

How Does Birefringence Affect the Polarization in Optical Fibers?

Applications that involve the transmission of data and light guiding are highly benefitting from fiber optic cables as they can safely transmit data at a wide bandwidth over long distances. This is why they find huge demand in industries like medical, military, and networking. Since unpolarized light travels through optical fibers with considerable losses and distortions, especially over long distances, it is critical to use polarized light in fiber optic cables for data transfer. To solve this problem, in-line polarizers are used as they help in facilitating the strongest and cleanest output signal. 

In-Line Polarizers – An Ideal Solution to Minimize Losses and Distortions

In-line polarizers are small pieces of cable in fiber capable of polarizing the incoming light signals. These devices are called in-line polarizers because they are positioned in-line with the fiber. Fiber with polarization controlled capacity can produce output signals with optimum intensity and bandwidth without causing any hindrance in velocity. 

Birefringence – How is it related to polarization in fibers?

Birefringence is an important property of optical materials where the refractive index is dependent on the incoming light’s polarization. This property is most commonly found in nonlinear crystals and various optical fibers as well. Though fiber cores with perfectly circular shape are considered to be ideal, most fibers in practical suffer mechanical stresses caused by bending or handling. This results in shifted geometry and that further leads to polarization-mode distortion along the length of single and multimode fibers. As a result, one polarization mode travels at a different space than the other. 

But, the question is how can birefringence affect the performance of optical fibers? 

Pulses lengthened due to birefringence produce noisier and lower quality output light signals. Since different polarizations of light can be absorbed by different materials at different angles, it becomes necessary to have control over polarization, particularly in optics applications because light polarization affects the focus of laser beams and which, in turn, influences the cut-off wavelengths of fibers. So, controlled polarization is critical to prevent undesired back reflections. 

Factors to Consider While Buying In-Line Polarizers

  • Insertion Loss: When a fiber optic polarizer is introduced in a system, it certainly causes attenuation. A good in-line polarizer is the one that causes minimized resultant loss. 
  • Bandwidth: Since different bandwidths are used in different applications, you must choose an in-line polarizer and fiber that can accommodate desired bandwidth.
  • Size: Usually smaller in-line polarizers are preferred because of the space constraints. Besides, they also come with lower insertion loss. 
  • Extinction Ratio: It is the ratio of the transmission of the desired polarization to the transmission of undesired polarization. Thus, it is the best indicator of quality for an in-line polarizer. 

Do you also need in-line polarizers? Keep in mind the above four factors to decide which one is the best for your application.
