Overview and classification of optical devices
Optical devices are also called photoelectron devices, which refer to various functional devices made by photoelectric effect. Optical devices are the key and core components of optoelectronic technology, and they have a wide range of applications, including optical communications, optical displays, mobile phone cameras, night vision glasses, low-light cameras, photoelectric sights, infrared detection, infrared guidance, medical detection and fluoroscopy, etc. Many fields are the frontier research fields of modern optoelectronic technology and microelectronics technology, as well as an important part of information technology.
Optical devices are usually divided into two categories, one is passive optical devices and the other is active optical devices. Passive optical devices can realize the functions of optical signal connection, splitting, coupling, attenuation, wavelength multiplexing, etc., but do not perform photoelectric signal conversion. Such products mainly include optical fiber connectors, optical isolators, optical splitters, optical Attenuators, CWDM/DWDM, etc.; optical active devices require photoelectric signal conversion, including lasers, optical modulators, optical detectors, optical transceiver components, etc.

Market size of optical devices
The market demand for optical devices mainly comes from downstream telecom operators' optical network upgrades and Internet service provider IDC internal and IDC interconnection construction. In recent years, with the rapid development of the 5G industry and the construction of big data "in full swing", the global optical device market is also in a state of continuous growth. According to Ovum data, the growth rate of the global optical device market from 2016 to 2020 has maintained a growth rate of 6%, with sales exceeding 12.2 billion U.S. dollars in 2020.

The world is currently in a critical period of transition from 4G to 5G society. Due to the differences in the business development speeds of the three types of 5G (enhanced mobile broadband, massive Internet of Things, and high-reliability and ultra-low-latency communications), the construction of 5G networks will be a gradual process. The process, the construction period is longer than 4G, it is expected that in the next few years, the investment of operators in the construction of 5G networks will drive a huge increase in the demand for optoelectronic devices. On the other hand, the explosion of data traffic continues to promote the expansion and construction of global IDCs, and the demand for optical components for data communication applications maintains rapid growth. On the whole, driven by 5G and the data economy, the market scale of optical devices and related industries will generally be on the rise in the next few years.
The competitive landscape of the optical device market
The optoelectronic device industry has a wide range of products, and different companies have specific advantages in different fields. At present, domestic companies have a certain competitiveness in the optical passive device market, but in the optical active device market, they are basically dominated by foreign brands.
At present, the main players in the global optical passive device market are II-IV, Lumentum, Finisar, NPTN, Sumitomo, etc.; domestic companies mainly include O-Net, Accelink, etc.

Analysis of the development trend of optical devices
From the perspective of future development, several changing trends in transmission devices in the next few years include: development toward higher speeds, continuous sinking of coherence, development toward flexible optical switching, and development toward wider communication windows; development trends of data center optical modules It is still high-speed and high-density. In 2020, the industry has begun to conduct 800Gbps technical research, and on-board optics has become a hot topic in the industry. In the future, as the challenge of switching chip power consumption becomes greater and greater, on-board optics may replace some short-distance pluggable modules due to its advantages of low power consumption and high integration. In terms of 5G fronthaul, due to the differences in scenarios and the advantages of various solutions, the trend of 5G fronthaul technology may continue to coexist with multiple solutions. The standard of the next-generation technology after 10GPON still needs to be explored.
