company news about OFC exclusive interview with Qixin Optoelectronics: Follow the design concept of higher performance and lower power consumption

"High speed, low power consumption and more sustainable development have always been the goals of the digital communication market, while in the telecom market, the requirements for power consumption indicators are not so strict. However, from the perspective of communication system, when modules with 8 to 16 ports are placed side by side and heat dissipation through Cage, heat source concentration leads to low system heat dissipation efficiency. However, the design of low-power optical module can not only reduce the power consumption of optical module itself, but also effectively improve the heat dissipation efficiency of the system level, helping operators to save more operation and maintenance expenses. Meet the overall layout requirements of the national energy conservation and emission reduction." Recently, in OFC2023, Qi Chip Photoelectric general manager Cheng Dong said in an interview with fiber online.

As we all know, Qixin Optoelectronics has the core technology of multi-material heterogeneous integration with high refractive index difference, ultra-low loss, tiny size and multi-layer loop. Based on materials, Qixin Optoelectronics designs multi-channel high-rate optical devices, and actively carries out the technological evolution from integrated packaging to on-chip integration. Qixin Optoelectronics has developed the technology of replacing EML with DML laser, single-wavelength single-fiber bidirectional technology and ultra-large scale optical switching technology. All these innovations are rooted in following the design concept of higher performance and lower power consumption.

From the perspective of the national strategy of "dual carbon" and "counting in the East and counting in the west", telecom operators will further optimize the allocation of computing resources and network interconnection, and further put forward the requirement of reducing power consumption in the optical interconnection and wide-connected wireless base station network.

In terms of access network, the CPON office-end optical module designed by Qixin Optoelectronics can effectively reduce power consumption by more than 20% based on its DML replacement of EML laser technology.

In the aspect of long-distance transmission, for the transmission of 10G/25G 40km/80km, Qixin Optoelectronics based on its technology of replacing EML laser with DML reduces the power consumption to a greater extent to meet customers' pursuit of low power consumption and low cost.

For the application of transmission and return in 5G wireless network, the three major operators are actively promoting the green and low-carbon 5G network construction. 's core photoelectric 50 g Bi - Di single wavelength light module based on its unique design of PIC light filter design using wavelength to use less and less with the design concept of optical fiber, receiving and emission wavelength of 1310 nm using commonly used, on both ends of optical fiber using the same kind of light module, do not need to distinguish when to deploy and maintain optical module, at the same time of cut link delay an order of magnitude, It also reduces the cost of system laying and maintenance management. Single light module power consumption is less than 4.5 W, is wide connections for the future of 5 g network power consumption is a very friendly setting.

For the next generation of products, Mr. Cheng said that Qixin Optoelectronics not only relies on the supply chain to reduce costs, but more importantly pursues the technological evolution of integrated packaging to on-chip integration, and further solves the design of the next generation of higher speed module products from high performance, low power consumption and low cost by means of semiconductor integrated circuit design. Further help customers to achieve high performance, low power, low cost solutions.

The unique large-scale photonic integration technology platform of Qixin Optoelectronics, which is compatible with CMOS technology, has completely created the key process foundation of three-dimensional heterogeneous integration of multi-materials. Qixin Optoelectronics welcomes extensive cooperation on PIC epitaxy, joint design flow, active passive packaging, encapsulation equipment, OEM business and intelligent factory, so as to better promote a new industrial ecology based on innovative design and innovative materials.
