2020-2026 Light Module Market Forecast

Third, the light module competition is fierce, and the share of domestic manufacturers continues to rise

The upstream of the light module industry mainly includes optical chips, battery chips, and optical components. There are many suppliers in the optical component industry, but high -end optical chips and battery chips have high barriers to technology and high R & D costs. They are mainly monopolized by overseas companies. The light module industry is located in the middle reaches of the industrial chain, and it belongs to the packaging link with relatively low technical barriers. The downstream of the optical module industry includes the Internet and cloud computing companies, telecommunications operators, data communication and optical communication equipment vendors. Among them, the Internet and cloud computing companies and telecommunications operators are the end users of the light module.

The key technologies of upstream high -end optical chips are monopolized by a few foreign manufacturers. The market concentration in the downstream industry is high, and the bargaining ability of head enterprises is very strong. The light module industry is under the pressure of upstream and downstream, the bargaining ability is relatively weak, and the industry is competitive. It is necessary to establish a relatively stable upstream and downstream cooperation relationship through scale advantages, technical iterative and reliable delivery capabilities.

Fourth, the development trend of the light module industry

1. miniaturization

At present, the competition in the optical communication market is becoming more and more intense, the volume of the requirements for communication equipment is getting smaller and smaller, and the interface density contains the interface board is getting higher and higher. The light module of traditional laser and detectors is difficult to meet the requirements of modern communication equipment. In order to meet the requirements of communication devices for optical devices, the light module is developing highly integrated small packaging development. Highly integrated photoelectric modules make users not need to process high -speed simulation photoelectric signals, shorten the R & D and production cycle, reduce the types of complicated gas procurement, and reduce production costs. Therefore, it is also favored by equipment manufacturers.

2. Low cost, low power consumption

The volume of the communication equipment is getting smaller and smaller, and the interface density contains the interface board is getting higher and higher, and it is required that the optoelectronic devices are required to develop in the direction of low cost and low power consumption. At present, the optical devices generally use hybrid integration processes and gas packaging processes. The next development will be a non-gas packaging. It needs to rely on technologies such as passive optical coupling (adjustment of non-X-Y-Z direction) to further increase the degree of automation production and reduce costs.

3. High speed

People have more and more information requirements, and the requirements for information transmission rates are getting faster and faster. As a modern information exchange, processing, and transmission of major pillars, Optical Sailing Network has been continuously developing to ultra -high frequency, ultra -high and large capacity development, transmission transmission, transmission, and transmission. The higher the speed and the larger the capacity, the cost of transmitting each information is getting smaller and smaller.

4. Long distance

Today's optical network laiding is getting farther and farther, which requires the remote transceiver to match it. The typical long -range transceiver signal can be transmitted at least 100 kilometers under unpredable conditions. The purpose is to save expensive optical releases and reduce the cost of light communication. Based on the consideration of the transmission distance, many remote transceiver chose 1550 bands (the wavelength range is about 1530 to 1565nm) as the working band, because the light waves have the least losses during the transmission of this range, and the available lithography players work in this way. Band.

5. Hot insertion

That is, no need to cut off the power, the module can be connected or disconnected with the device. Because the light module is hot -inserted, the network manager can upgrade and expand the system without turning off the network, which will not affect online users.The heat insertion also simplifies the overall maintenance work and enables end users to better manage their receiving modules.At the same time, due to this thermal exchange performance, the module allows network managers to upgrade the transceiver cost, link distance and all network topology according to the network upgrade requirements, and no need to replace the system board.
