Dream with Light, Build Light with Core: Yongding Optoelectronics Runs "New Raceway"

At present, as China continues to improve the coverage of 5G dual-gigabit network, 5G front-pass network, OTN all-optical network, metropolitan area network construction is rapidly advancing, and accordingly, the demand for optoelectronic chips, optical devices, optical modules and other products supporting high-speed transmission in the 5G era is increasing day by day. Wuhan Yongding Optoelectronics Group Co., Ltd. (hereinafter referred to as Yongding Optoelectronics) has firmly grasped the opportunity of 5G dual gigabit network construction in recent years, focused on domestic and foreign market demand such as OTN, 5G bearer network and data center, vigorously promoted independent innovation and research and development, and made remarkable achievements in realizing the localization and substitution of high-end optical chips, devices and optical modules.

TFF is the core chip in the DWDM transmission network and is widely used in OTN backbone, metro network and 5G fronthaul network. Yongding Optoelectronics recently announced to overcome the technical difficulties of temperature drift, the introduction of 100GHz DWDM TFF film filter, product performance and reliability have reached the international advanced level, to achieve TFF chip independent localization.

Yongding Optoelectronics currently has 100GHz DWDM TFF in mass production and commercial use in the global telecommunications network, 50GHz DWDM TFF has completed small batch trial production, and also accepts TFF and Z-Block products Z-Block customized CWDM4 and LWDM. The product has passed various reliability tests, passed ultra-high temperature aging at 120 ℃ and double 85PCT test for more than 1000 hours, meeting the international GR-1221-CORE reliability standards for passive devices. DWDM products of various package types have been shipped to more than 1.2 million channels, with a cumulative output value of more than 0.1 billion yuan.

In the 5G dual gigabit era, products such as optical chips and optical modules with ultra-high speed and ultra-low power consumption have gradually become the "commanding heights" for manufacturers to compete for positions ". China's "14th Five-Year Plan for the Development of the Information and Communication Industry" and "Several Policies to Promote the High-Quality Development of the Integrated Circuit Industry and Software Industry in the New Era" also encourage and support from the policy level, guiding enterprises to strengthen the layout of optical chips and devices, optical modules in the field to meet the needs of the operator market and the digital communication market.

Yongding Optoelectronics grasps the pulse of the market and strives to run the "new track" of the optoelectronic industry. Currently, passive TFF and AWG chips, active VCSEL, DFB and APD chips have been commercialized to WDM, AAWG, optical modules and forward semi-active systems. Up to now, Yongding Optoelectronics has the latest WDM series products, including TFF and AWG platforms with independent chip technology, and 25G 10G full series WDM color light modules, which are especially suitable for 5G network fronthaul application solutions. There are also MT, MPO, 4CH/8CH AWG products and solutions to meet market needs at different levels.

Thanks to Yongding Optoelectronics for many years uphold the spirit of independent innovation, vigorously promote research and development, Yongding Optoelectronics focus on building a localized industrial chain ecological development, complete the chip-device-module-system industrial layout, has become one of the outstanding enterprises in the optical communication market, to win the broad market space to lay the foundation. At present, Yongding Optoelectronics is actively laying out, providing customized products and solutions for domestic and foreign operators and equipment manufacturers, optimizing and upgrading service quality, and further expanding multi-directional cooperation. It has successively applied optical devices, optical modules and wavelength division subsystems in 5G networks such as domestic operators and overseas operators.

Dream with light, build light with core. As China's 5G network construction has entered a period of rapid development, the demand for optical chips and devices and optical modules has ushered in massive growth. Yongding Optoelectronics will continue to polish advanced technologies in the future, continuously enhance its core competitiveness, strengthen and extend cooperation in the optoelectronic industry chain, and contribute to accelerating the localization of optical chips and devices and optical modules in China.
