Download | Serving the 100 billion optical module market, what "hard" solutions does Murata have?

With the explosive development of emerging technologies such as 5G, AI, and the Metaverse, the new generation of information technology is accelerating its integration with all walks of life. Cloud computing demand and data traffic continue to grow. More diverse connected devices and complex application scenarios have put forward higher requirements for data processing capabilities. IDC predicts that the scale of intelligent computing power is expected to exceed 1117.4EFLOPS by 2027. As an important foundation of computing power networks, the market size and technological development of optical communication networks are also strong (see figure below) - According to Yole's market analysis, the optical module market has achieved a compound growth rate of 11% in the past five years, and the market size in 2029 will exceed US$200 billion.

As the complexity of data-intensive applications continues to grow, the need for high-speed transmission and efficient communication between computing units has become critical. The optical modules in network equipment must have higher stability and transmission capabilities to support the rapid processing of massive data and low-latency communication, providing reliable guarantees for the smooth operation of these data-intensive applications.

Murata's ultra-wideband silicon capacitor products effectively solve the pain points of optical modules in terms of integration and transmission rate. It can handle up to 220GHz. The products include surface-mount capacitors suitable for signal line AC coupling, DC decoupling wire bonding capacitors that can be used for TOSA/ROSA bias lines, and customized silicon substrates with integrated RC. Murata's silicon capacitor products have high capacitance stability under temperature, voltage and aging conditions, high capacitance density and high integration technology, which can achieve thinner designs and more flexible mounting methods while maintaining high performance, which can effectively help optical modules meet the challenges of integration and transmission rate.

Murata's miniaturized, large-capacity multilayer ceramic capacitors (MLCCs) have high effective capacitance density and low ESL/ESR characteristics , which can not only help devices better cope with the challenges of high currents, but also effectively solve the equipment space problem and improve the reliability and operating efficiency of the overall system.

Murata demonstrated two sets of Bias-T inductor solutions for high-frequency and low-frequency applications in optical transceivers at this year's CIOE . They can provide an inductor combination with excellent insertion loss characteristics in a wide bandwidth, bringing outstanding high-frequency characteristics and small-sized inductor devices to high-speed optical transceivers.

As the demand for computing power increases, problems such as equipment energy consumption and heat dissipation will inevitably arise, which will undoubtedly bring new challenges to the industry. How to achieve high efficiency, low power consumption, continuous and stable power supply and ensure the safety of the data center environment has become the focus of the industry.

Murata's star products PE24108 and PE24110 power chips, which are lower in height and more compact in size, adopt innovative two-stage architecture and staggered phase technology. The internal front stage adopts Murata's special switch capacitor technology, and the back stage adopts staggered phase buck to achieve ultra-low power IC solutions. Help customers achieve ultra-low power consumption, ultra-low ripple in high-speed optical modules in coherent and incoherent fields, and provide front-end design requirements.

In addition, Murata also displayed an ultra-thin liquid wick made of finely processed copper foil, which has several times the capillary force . This product can further improve the performance of the temperature equalizer and reduce its thickness to less than 200μm. Through the corresponding changes of the liquid in the temperature equalizer, the heat generated by the heat source can be absorbed, diffused and dissipated, achieving uniform heating of the entire machine and avoiding local overheating.

Aiming at the two major pain points of power management and circuit protection, the thermistor products displayed by Murata this time are small in size and very suitable for temperature detection, temperature compensation and overcurrent protection in data centers .

At the exhibition, Murata also brought a number of innovative products suitable for the field of optical communications, including power inductors, crystal oscillators, and micro batteries, providing full-range product support for the industry's technological development.

During the CIOE exhibition, Murata silicon capacitor engineer Olivier Gaborieau shared his experience at the " Intelligent Computing Center Optical Technology Innovation and Development Forum " on the topic of " How to use Murata UBB silicon capacitors to reduce the power consumption of high-speed optoelectronic modules . "

With its industry-leading innovative technological strength, Murata will continue to work with customers and industry partners to create unlimited possibilities for electronic components, build a solid energy foundation with innovative technologies and high-quality products, and promote high-efficiency and high-quality development of the optical communication industry.
