Fundamental Things You Need To Know About Passive Electronic Components!!

Regardless of whether you know it or not, one of the crucial factors that distinguish kinds of electronic components from one other is if they are active or passive. Although, tons of individuals are still unsure about the difference! On the off chance, if you also fall under the same category of individuals, there is nothing to feel embarrassed as we have got you covered.

Mentioned below is the difference between active and passive components. So, keep reading.

The Difference

Active components: These are crucial parts of a circuit that entirely depends on an external power source to manage or modify electric signals. For your better understanding, active components such as transistors and silicon-controlled rectifiers (SCRs) utilize electricity to handle electricity.

Passive components: High power components such as resistors, transformers, and diodes do not consume external power source to function precisely. These high power components utilize some different properties to manage the electrical signal, as an outcome, they only need the current going via the connected circuit. Resistors hinder the flow of electrons without transferring more electricity into the system. The two precisely explained high power components examples are listed below.

1. Capacitors: A capacitor also called as condenser is a passive two-terminal electronic component that is utilized for storing energy electro-statically in an electric field.  There are various forms of practical capacitors, yet each and every one still contain at least two electrical conductors that are separated by an insulator aka dielectric. The conductors can be in the form of thin films, sintered beads of metal, foils or conductive electrolyte. The non-conducting insulators are used to double the charge capacity of condenser. An insulator can be made of glass, ceramic, plastic film, air, vacuum, paper, mica, oxide layer etc. In plenty of electrical devices, capacitors/ condensers are widely used as parts of electrical circuits. Unlike a resistor, an optimal condenser does not squander energy. Rather than dissipating, a capacitor stores energy in the state of electrostatic field between its plates.

2. Resistors: A resistor is a passive two-terminal electrical component that applies electrical intransigence as a circuit element. Resistors are generally used to lessen the current flow, and, at the same time, they are also used for lowering the voltage levels within circuits. In electronic circuits, there are utilized to restrict current flow, adjust signal levels, bias active elements, terminate transmission lines and the list is endless. High-power resistors that are capable of dissipating loads of watts of electrical power can also be used as part of motor controls, in power distribution systems, or as test loads for generators. In addition to this, resistors may comes with fixed resistances that only get changed with a cold temperature, time or operating voltage. Also, variable resistors can be used to adjust circuit elements.

So, these were some of the most imperative things that you should know. For any further clarification and information, please get in touch with us whenever you want.

What is Wavelength-Division Multiplexing and Its Benefits?

A technical solution that permits the combination (“mux”) of several separate light wavelengths (signals/channels) from different lasers on a single fiber utilizing a passive component for transmission to another site is called Wavelength-division Multiplexing (WDM).

The WDM components then demultiplex the combined wavelengths at the receiving location and route them to their appropriate receivers.

The Main Components of WDM System

In a WDM system, there are two different types of approaches:

  • Dual-fiber unidirectional transmission
  • Single-fiber bidirectional transmission.

The simultaneous transmission of multiple optical channels on a fiber propagating in one direction is known as dual-fiber Unidirectional WDM.

There are separate wavelengths that convey different paths across an optical fiber. At the transmitting end, these signals are combined for transmission across the fiber and demultiplexed to complete multiple paths at the receiving end.

It is necessary to use a second optical fiber for the opposite direction of the transmission. And since the transmission takes place in both directions, it is vital to use two optical fibers.

Bidirectional WDM is the simultaneous transmission of optical channels in both directions on a fiber, with the wavelengths employed segregated to achieve full-duplex communication between the two sides.

The standard components of a WDM system are:

  • The network management system
  • Optical transmitter
  • Optical relay amplifier
  • Optical receiver
  • Optical monitoring channel are.

The WDM system’s overall structure

Transceivers, WDM wavelength division multiplexers, patch cords, and dark fiber components make up the basic WDM system.

WDM system

The multiplexer and demultiplexer are critical components in the WDM technology, and their performance is crucial for the system’s transmission quality.

What are the benefits of using WDM Technology?

  1. Large Capacity

WDM’s main advantage is that it can fully utilize the optical fiber’s bandwidth resources and enhance data transmission capacity without requiring changes to the current network architecture. It allows an optical fiber’s transmission capacity to multiply a single wavelength.

2. Excellent Compatibility

WDM has a wide range of signal compatibility. Each wavelength is independent of the others and does not interfere with each other when transmitting signals with diverse qualities such as pictures, data, and sound to ensure transmission transparency.

3. Flexibility, Cost-effectiveness, and Dependability

WDM technology enables the addition of new channels as needed without disrupting the existing network, making upgrades convenient.

There is no need to replace the optical cable line when updating or increasing the network. New enterprises can be added or superimposed by adding wavelengths.

Large-capacity long-distance transmission can conserve optical fibers and 3R regenerators, lowering transmission costs dramatically.

4. Wavelength Routing

WDM is one of the most critical technologies for implementing all-optical networks. The up/down and cross-connection of various telecommunication services can be implemented by altering and adjusting the wavelength of the optical signal on the optical path.

A reputable designer and manufacturer of high-quality optical passive components can provide a comprehensive portfolio of WDM solutions tailored to your unique needs, allowing you to achieve system goals in the most efficient way possible.
