The modern history of mankind in the past century has achieved an unprecedented rapid technological evolution in the past two decades. Intelligent IOT, cloud, blockchain, big data, driverless… An endless stream of innovative technologies are subverting the traditional human life mode. All these are based on high-speed data connection infrastructure. Modern cities are rapidly entering the era of 10 Gigabit connection – 10 Gigabit enterprise access, 10 Gigabit home broadband access, 10 Gigabit personal wireless access experience. The industry predicts that by 2030, the global 10 Gigabit enterprise WiFi penetration rate will reach 40%; The global optical fiber broadband users will reach 1.6 billion, and the broadband penetration rate of 10 Gigabit households will reach 23%; The total number of global connections has reached 200 billion, and the data generated worldwide will reach 1yb, 23 times that of 2020.

Behind this, optical communication technology plays a key role. According to the latest report on the global optical module Market released by the well-known market research organization lightcounting, the optical module market will be US $8 billion in 2020 and is expected to increase to US $14.5 billion by 2026. The compound growth rate of the global optical module market will reach 10.4%. “We can see that the demand for optical modules is growing rapidly on both the telecom side and the data center side.” ADI optical communication product line market and Application Manager pointed out at the recent China Optical Expo in the summer. As a provider of high-performance semiconductor solutions, ADI provides a wide range of product solutions in the field of optical module applications, such as control units, optical path circuits and power supplies. The new generation of optical module control solution aducm43x, which debuted at the optical Expo, aims to create a very flexible platform solution + excellent system cost competitiveness, and is expected to become a “new favorite” in the 400g / 800g optical module market.

ADI optical communication product line market and Application Manager

The latest one specialty multi-function control platform is on the market, and the fourth generation optical module controller leads the high-speed development trend

At the optical Expo site, ADI focused on displaying its rich optical module related product solutions, including the main series of products from the first generation to the fourth generation controller, optical module power supply solutions, thermoelectric cooler regulator modules, and so on. The control unit realizes the configuration, adjustment and real-time monitoring of various components in the optical module through single chip microcomputer. When the module is powered on, the single chip microcomputer loads and initializes each chip. After the module works normally, the single chip microcomputer monitors and adjusts the working state of each component in real time.

The fourth generation optical module controller series products aducm43x and cmis4.0 solution based on aducm430, which are available for the first time, are undoubtedly the “traffic responsibility” of the whole audience. “Aducm43x series is a new generation of optical module control solution developed by ADI’s local team. It mainly embodies the compatibility of general digital resources + differentiated memory + differentiated analog peripherals + pin2pin, and provides an extremely flexible platform scheme + excellent system cost competitiveness.” Summer pointed out that “aducm43x is mainly used for 200 / 400 / 800g DML / EML / silicon optical modules. It optimizes the small size, low power consumption and ease of use of high-speed optical modules, mainly reflecting four advantages.”

The four product advantages of aducm43x in summer include——

High integration meets the requirements of high channel density of high-speed optical module. In order to meet the high channel density requirements of high-speed optical module, the high integration scheme integrates multi-channel 12 bit SAR ADC, multi-channel voltage DAC, multi-channel current output DAC and thermoelectric cooler (TEC) controller. Aducm43x integrates the functions that originally needed 3 ~ 4 chips and adopts 5mm * 5mm 121 pin BGA package, which is very suitable for the small size of optical module in the future.

High performance simulation technology once again highlights ADI’s “housekeeping skills”. The linearity and noise index of ADC / DAC integrated on the chip are very high, while MCU and Tec controller have achieved the maximum efficiency optimization, and the power consumption advantage of the scheme is obvious. At the same time, the chip has made a lot of optimization on the input and output differential pressure, which reduces the input and output differential pressure, further reduces the power consumption of the chip, and the performance is more in line with the needs of the current industry.

Ease of use accelerates the application of products. Aducm43x is mainly aimed at the application of 200 / 400 / 800g DML / EML and silicon optical module, and has different customized designs for different application scenarios. It can not only support small size, but also realize the flexible configuration of flash size, the number of channels of analog resources and other requirements, and even provide options for different package sizes. In addition, for the 400g module, aducm43x supports this year’s cmis4.0 protocol and introduces supporting software. These software can help customers develop their software faster to adapt to the cmis4.0 protocol.

ADI China local team research and development to better meet domestic users and ensure supply chain security. As a new generation of ADI localized optical module control product, the launch of aducm43x will better meet the design needs of domestic optical module market and customers.

“ADI is very farsighted and has long been optimistic about China’s optical communication market. It has been nearly 20 years since it began to layout the optical communication product line in 2005. Before aducm43x, there were almost 20 models of three generations of products. All the designs were completed by China’s local R & D team and successfully put into the market. It has achieved great success, with an annual shipment of more than 2 million pieces.” For the last key point, summer added.

ADI six dimensions to build the core competitiveness of optical module product solutions.

“From chip level support to support in the field of new technologies and products, we have a lot of very close and fruitful cooperation with Chinese communication equipment suppliers and customers, including completing a lot of work such as product definition and product application development with them. On the basis of continuing to establish a deep partnership with Chinese customers, we have developed a series of very successful products.” Xia Xia said, “we are very optimistic about China’s potential in the field of optical communication. The fourth generation products of ADI R & D center have witnessed and strongly supported the rapid development of China’s optical communication industry.”

In fact, the past ten years are also the golden period for the rapid development of China’s optical module enterprises. According to the report data of lightcounting, six domestic manufacturers were listed in the top ten global optical module manufacturers in 2020, dominating the global optical module market, while only one Chinese enterprise entered the top ten in 2010. Today, China’s optical communication module products occupy a leading share in the global market, and Adi optical module controller is almost the general solution of these enterprises. “In the most active market in China, we need to establish a very close relationship with our customers, especially a technology to technology and engineer to engineer relationship, to help our customers solve the most difficult challenges and help our own products do better.” Summer added, “benefiting from the construction of data center and the in-depth layout of 5g network, the global market share of domestic optical module enterprises has increased, and the demand of optical module downstream operators has expanded. We are optimistic about the opportunities for further growth of Chinese optical module enterprises in the future.”

Actively create localization schemes to enable the data flood era with a comprehensive product portfolio

As an important measure for ADI to implement the localization strategy in the Chinese market, ADI established the Chinese products division and upgraded adeno semiconductor technology (Shanghai) Co., Ltd. to adeno Investment Co., Ltd. at the end of last year. As the headquarters operation organization of ADI in China, based on this, ADI has realized a more complete layout in the process of localization.

“The establishment of ADI China headquarters is based on the consideration and layout of localization. The launch of a new generation of optical module control series product aducm43x is a masterpiece of localization. Localization has been fully realized from the front-end to IP design, as well as the back-end packaging, testing, production and manufacturing.” Xia Xia pointed out that “ADI is willing to cooperate with all domestic optical module enterprises and optical device enterprises, and even hold an open attitude in the integration and packaging at the bare chip level. With these measures, ADI can better serve the local market, which is also ADI’s investment and determination in the optical communication market, especially China’s optical communication market.”

After ADI completed the merger and acquisition of Maxim, it further enriched the optical module application product portfolio

In fact, a small optical module is also a complex photoelectric system. In addition to optical devices and core control units, amplifiers, drivers, thermoelectric coolers, power supply devices and so on are essential. “ADI has a wealth of optical module core devices and peripheral devices. These products provide a rich and flexible scheme combination for optical module manufacturing. For example, our third-generation controller aducm410 has 16 ADC channels, but if customers need more analog channels, ADI has many general ADC / DAC that can be matched to form a more complete scheme, such as ad5770r; in addition, as a well-known Tec controller in the industry, adn8833 continues to It has a very wide range of applications and a very good reputation in this market. ” Speaking of various product solutions, summer is like a treasure.

It is worth mentioning that with the completion of ADI’s acquisition of Maxim, ADI has further achieved strong integration in the field of optical communication semiconductors. “Maxim also has rich products and profound technical accumulation in key components of optical modules such as power supply, laser driver, TIA and CDR. For example, ds4830 and ds4835 series controllers are widely used in the global optical module market. At present, the product lines of both sides are being integrated, and I believe we will provide you with more competitive solutions in the future.” Summer said. With the development of optical modules to 400g and 800g high-speed communication, small package, high-speed and high-channel density undoubtedly put forward higher requirements for integrated solutions. For example, aducm430 will realize highly integrated solutions by integrating Tec controller, PMIC and other on-chip devices. In the future, ADI will continue to provide a rich product portfolio with more integration and performance advantages in the field of optical modules.
