EXSENSE Electronics Technology Co., Ltd. has been committed to the research, development and production of NTC chip for optical transceiver for more than 13 years. Our NTC chip plays the role of temperature monitoring and temperature control in optical transceiver to ensure the stable work of optical module.
With the rapid development of modern science and technology, the capacity of information transmission in the field of communication is increasing day by day, optical fiber communication has become the main way of communication. The requirements for optical transceiver modules are also gradually improved, which are mainly manifested as high speed, miniaturization, low power consumption, long distance and hot swap. People need more and more information, which requires faster and faster transmission speed. As the mainstay of modern information exchange, processing and transmission, optical communication network is characterized by high frequency, high speed, large capacity, high transmission rate and large capacity, and the cost of sending each message is becoming smaller and smaller.
Optical devices generally adopt hybrid integration technology and sealed encapsulating process, and the next step is expected to be non-airtight development, which needs to rely on passive optical coupling technology to improve the degree of automatic generation and reduce costs. As the laying distance of optical network increases, the matching of remote transceiver is required, and the optical transceiver is required to develop to a long distance. The optical transceiver needs to support hot swap in the future, that is, when the power is not cut off, the optical module can connect or disconnect the device. In other words, the network administrators can upgrade and extend the system without shutting down the network, without affecting online users. Hot swap simplifies maintenance and enables end-users to manage their optical transceivers better. At the same time, due to the heat exchange performance, the optical transceiver can let the network administrators upgrade requirements and overall planning according to the network, without the need to replace all the system boards.
GBIC (Giga Bitrate Interface Converter) and SFP (Small Form Pluggable) are supported in the optical transceiver. Because of the size of SFP and the appearance, the setting trigger can be directly inserted in the circuit board, which has a wide application range. Therefore, its future development is worth looking forward to.
Silicon optical transceiver is expected to become a new driving force for optical communication industry. Silicon photonic technology is based on silicon and silicon substrate materials (such as SiGe/Si, SOI, etc.), the use of the existing CMOS technology for optical device development and integration of a new generation of technology, combined with the large scale integrated circuit technology, the characteristics of ultra precision manufacturing and photonic technology of ultra high speed, low power consumption advantages, it's a disruptive technology in response to the failure of Moore's Law. Silicon optical module has obvious advantages, including low energy consumption, low cost, large bandwidth and high transmission rate. However, due to the complexity of silicon optical chip materials and production technology, there are still obvious disadvantages, such as high cost and low technology maturity. With the development of silicon optical technology, the silicon market is expected to grow rapidly in the future. According to Yole's data, the silicon optical market size will grow at a compound annual growth rate of 44.5% from 2018 to 2024, and is expected to grow to $4 billion in 2024.
The main well-known enterprises in the international market, focus on high-end optical transceiver research, development and production. Under the background of the continuous development of optical communication industry, optical transceiver enterprises have accelerated merger and reorganization, carried out vertical integration of industrial chain, and further improved the industry concentration degree. Optical transceiver industry head enterprises to join forces, the degree of competition is gradually increasing. The head company is committed to the high profit field such as optical chip, the assembly industry is gradually transferred to China. According to data from Ovum, the sales rank of optical transceiver of domestic manufacturers is constantly improving. In recent years, domestic manufacturers have also stepped up mergers and acquisitions, constantly layout of high-end optical transceiver products, to achieve upgrading.
With the continuous advance and construction of 5G, the demand for optical transceivers is constantly increasing, which prompts the NTC chip market to expand and expand to keep pace with the development of optical transceivers.
