Optical communication industry chain

At present, the global data traffic is continuously exploding, and the improvement of electronic information computing and transmission capabilities has encountered bottlenecks, and optoelectronic information technology has ushered in rapid development.

In this wave of artificial intelligence technology innovation, North American computing power is the first to upgrade. my country's optical communication industry is one of the few sectors that can directly participate in global computing power construction. It is highly certain that leading manufacturers will win massive orders.

In the past ten years, the value of the global optical communication industry has shifted significantly to China, driving the rapid development of the domestic optical communication market.

my country's optical device and module suppliers are gradually gaining share in the global market, and domestic suppliers currently dominate the global Ethernet optical module market. In addition, in smaller market segments such as FTTx and wireless fronthaul, almost all Chinese suppliers. Unable to compete with Chinese suppliers, many non-Chinese suppliers have withdrawn from the optical module market one after another.

As the demand for optical communications in the construction of high-speed data centers continues to increase, the global market share of Chinese manufacturers is expected to further expand.

Omida predicts that the size of China's optical communication market is expected to reach 175 billion yuan in 2025, corresponding to a CAGR of 12% from 2022 to 2025.

Optical Communication Industry Overview

Optical communication is a system that uses optical signals as the carrier and optical fibers as the transmission medium to realize information transmission.

The essential driver of optical communication network construction is the rapid and continuously growing demand for data traffic.

With the continuous growth of data traffic, the data transmission and bandwidth pressure of the traditional bearer network continue to increase, and the transmission rate of the backbone network will continue to upgrade from 100G to 200G/400G/800G and other higher rates.

The optical communication network technology industry chain is the supply side, and traffic growth is the demand side.

What is the optical module for

Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. The optical module is also called a fiber optic transceiver, which is mainly used for photoelectric conversion of signals. At the transmitting end, the electrical signal of the device is converted into an optical signal, and at the receiving end, the optical signal is restored to an electrical signal. The optical module is composed of a laser at the transmitting end, a detector at the receiving end, and electronic devices for data encoding/decoding.

What is the principle of optical communication?

The principle of optical fiber communication is: at the sending end, the transmitted information (such as voice) must first be converted into an electrical signal, and then modulated onto the laser beam emitted by the laser, so that the intensity of the light changes with the amplitude (frequency) of the electrical signal. And send it out through the optical fiber; at the receiving end, the detector converts the optical signal into an electrical signal after receiving it, and restores the original information after demodulation.
