What Is Optical Communication and Its Advantages

Optical communication is a communication way with optical wave as carrier. There are two

methods to increase optical bandwidth: the first is to increase the single channel transmission

rate of optical fiber; the second is to increase the number of wavelengths transmitted in a single

fiber (WDM). Here Gigalight is going to introduce what optical communication and its main

advantages to help you know the field better.

What Is Optical Communication?

The basic optical fiber communication system consists of data source, optical transmitter, optical

channel and optical receiver. The data source includes all the signal sources, and they are the

signals obtained by the source code of voice, image and data. The optical transmitter and

modulator are responsible for converting the signal into an optical signal that is suitable for

transmission on the optical fiber. The optical wave window include: 0.85, 1.31 and 1.55. Optical

channels include the most basic optical fiber, and the relay amplifier EDFA, etc. The optical

receiver receives the optical signal and extracts the information from it, then converts it into

electrical signals, and finally obtains the corresponding voice, image, data and other information.

The computers and mobile phones around us send messages via electrical signals "0 and 1".

Optical communication consists of a "transmitter" that converts electrical signals into optical

signals, a “receiver” that converts optical signals into electrical signals, and "optical fibers" that

transmit optics.

Three Main Advantages of Optical Communication

1. Long Transmission Distance, Save Energy

suppose you want to transmit 10gb of information

Suppose you want to transmit 10Gb of information in one second (10 billion signals). If you use

electrical communication, you need to adjust the signal every 100 meters. In contrast, using

optical communication requires an interval of more than 100 kilometers. The fewer times the

signal is adjusted, the fewer machines will be used, thus saving energy.

For example, when you phone or chat online now with your foreign friends, you will feel there is

no difference with the domestic conversation, without lag in sound. In an era of electrical

communication, one can transmit at a short distance and transmit less information, and

international communication is mainly transmitted through satellite as relay. However, with

optical communication, one can transmit at a long distance and transmit more information.

Therefore, by using fiber-optic cables laid on the seafloor, it is possible to communicate with

overseas. Electrical waves have the same speed as optical waves. However, because the

transmission path is longer by satellite, the signal arrives slower. The submarine cable is much

shorter, so the signal will be faster.

2. Transmit Massive Amount of Information at One Time

Using optical communication, a large number of users can receive the required information at the

same time (movies or news, etc.). In one second, electrical communication can transmit only

10Gb of information (10 billion 0 and 1 signals). In contrast, optical communication can transmit

information of up to 1Tb (1 trillion 0 and 1 signals).

3. Fast Communication Speed

Electrical communication can cause errors in electrical noise, resulting in decreased

communication speed. However, optical communication is not affected by noise, so it can

transmit signals quickly.

Conclusion:

The ultimate goal of the future transmission network is to construct an all-optical network, which

is to fully realize "optical fiber transmission instead of copper wire transmission" in the access

network, metropolitan area network and backbone network. The backbone network and the

metropolitan area network have basically realized the all-optical network. In the today that

information society develops faster and faster, optical communication will inevitably facilitate the

further advancement of network.
