The Difference Between Optical Fiber And Led

Optical fiber and LED are both very popular light transmission technologies, they are widely used in communication, lighting, entertainment and other fields. Although they are both capable of transmitting optical signals, there are significant differences between them. This article will compare the two technologies from several aspects.

1. Principle

Optical fiber adopts the principle of total reflection and uses pure glass or plastic fiber as the transmission medium to transmit optical signals between fibers through reflection transfer, eliminating the influence of electromagnetic interference and signal attenuation. Therefore, it has good transmission performance and security performance, and is widely used in the field of communication.

The full name of LED is "Light Emitting Diode". It is an electronic device that emits light when current is passed through a semiconductor material. Therefore, it has the advantages of long life and low energy consumption. It is widely used in low frequency lighting, fluorescent screens, indicators and other fields.

Step 2: Use

Optical fiber is mainly used in data transmission, communication, room wiring and other fields. Because of its low delay and high rate transmission ability, network communication usually adopts optical fiber transmission technology, and the data transmission rate can reach Tbps.

LED is widely used in lighting, display, indication and other fields, LED bulb life cycle can exceed 50,000 hours, not only durable and provide bright light source, can be used in outdoor or indoor applications.

Step 3: Price

Fiber optic technology uses expensive glass materials and high-end light technology, which makes it more expensive than leds. The price of optical fiber communication is higher for users, but its advantages such as transmission quality and transmission rate also have corresponding market demand.

Leds, by contrast, are cheaper but have a higher combined cost than regular fluorescent bulbs, so they are more widely used.

Step 4 Be safe

Optical fiber has high security and privacy. Because the signal transmission of optical fiber takes place between fibers, it is relatively safe and not interfered by electromagnetic signals. This makes it ideal for applications related to confidential data.

LED will not leak personal information, but it will be a threat to human safety. High brightness LED light source is easy to stimulate the human eye, irradiation time is too long may cause damage to human eyes, should pay attention to safe use.

In general, although optical fiber and LED are both light source technologies, their uses and principles are very different, and each technology is suitable for different fields or products. Both optical fiber and LED have their advantages and disadvantages. We should choose according to our needs.
