On March 17, the Laser World of Photonics China 2021 was grandly opened at Shanghai New International Expo Center, and Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC) (Stock Code 601869.SH, 06869.HK) exhibited diversified products and solutions such as industrial lasers, optical interconnects for data centers, automotive and laser components, optical fibre sensing, HDMI active optical cables, optical transceivers and synthetic quartz materials, and held a promotional event for specialty products at the booth, attracting a great deal of attention. Furthermore, upon invitation, Yan Changkun, Senior Vice President of YOFC, attended the "Making Friends with Time: The First Chinese Listed Laser Companies Summit & Laser Leaders Conference" held simultaneously with the Laser World of Photonics China 2021.

Industrial Laser

​YOFC provides a wide range of products designed for the industrial laser industry, including customized optical fibre preforms, active optical fibres, a full range of passive optical fibres, high-power fibre bragg gratings, TGG crystal materials, fluorine-doped capillary tubes and other core products. With excellent laser activity and long-term reliability, the products effectively provide momentum for rapid development of the industrial laser sector. At the Laser World of Photonics China 2021, YOFC exhibited the ring fibre with excellent fibre laser welding performance with emphasis. In the future, more products which are satisfactory to and even beyond expectations of customers will be developed.

Data Center

In the context of "new infrastructure construction", YOFC has made use of over 30 years of rich accumulation in optical communication to comprehensively improve the efficiency and reliability of data interaction of data centers. At the Laser World of Photonics China 2021, YOFC displayed all-optical data center interconnect solutions and cutting-edge research results, including communication-oriented optical fibres and cables, active optical cables, MPO/MTP branches and jumpers, optical fibre amplifiers, dispersion compensation modules, multi-core/few-mode fibres and modules, equipment systems and platforms, demonstrating YOFC's capabilities of diversification in optical communication.

Automotive Optical Component

In the context of 5G network construction, driverless technology is gaining rapid development and the vehicle-mounted LiDAR which serves as the “eyes” for autonomous vehicles has become one of the most important sensors. The wavelength of 1550nm, which is safe for human eyes, is ideal optical source for vehicle-mounted LiDAR. At the Laser World of Photonics China 2021, YOFC exhibited automotive optical connection components, polarization-maintaining EDFA modules, dual-channel EDFA modules and other products, providing new optical amplification solutions for automotive LiDAR. It is the result of YOFC' in-depth researches on 1550nm optical amplifier modules and related products on the basis of its advantages in special optical fibres.  

Optical Fibre Sensing

Optical fibre sensing technology is widely used in many fields such as unmanned driving, hydrological survey, petroleum exploration and exploitation, and railway transportation. YOFC has developed a range of special devices and products and sensing systems on the basis of special optical fibres and its advantageous PCVD-based technique of manufacturing optical fibre preforms. At the Laser World of Photonics China 2021, YOFC mainly displayed optical fibre hydrophone system solutions and a variety of special optical fibres and cables such as radiation-resistant optical fibres and cables, high temperature optical fibres and cables, temperature measurement oriented optical cables and security protection oriented optical cables, receiving extensive attention of the customers.

Active Optical Cable

In the active optical cable exhibition area, YOFC mainly displayed active optical fibre data cables such as Commercial HDMI2.0 and Pure3 8K HDMI2.1. In particular, FIBBR Commercial HDMI 2.0, a product designed for engineering purposes, can withstand 3,000 times of bending and realize 50m loss-free signal transmission. With small joints, high flexibility in wiring and adaptability to harsh environment of -40℃ to 85℃, it is a professional engineering-oriented cable. Pure3 8K HDMI2.1, which is featured with bending resistance and highly efficient and loss-free transmission, can fully meet customers' needs for high-definition display and stereo sound effect in applications scenarios such as home audio and video, 8K and VR.

Optical System

Fibre bragg gratings are indispensably important for applications such as optical fibre communication and lasers. YOFC’s fibre laser-oriented fibre bragg grating uses rare-earth-doped fibre as the gain medium, which helps to form a stable laser output and allows the customization of the type and length of the fibre. Furthermore, the temperature increase characteristics of high-power fibre bragg gratings are above the industrial standards and users can always find what they need from a wide variety of products. At the Laser World of Photonics China 2021, YOFC mainly displayed 4KW fibre bragg gratings, fibre bragg gratings for thulium-doped fibre lasers, and 3KW unencapsulated fibre bragg gratings.

Optical Transceiver

By fully integrating platform resources, YOFC has developed a complete industrial chain covering device encapsulation, optical cable production and module assembly, and created a unique automated manufacturing system in the industry. YOFC's optical transceiver s, which are characterized by miniaturization, low power consumption and low cost, are widely used in 5G fronthaul and data centers. YOFC provides a full range of optical modules covering 100M, 1.25G, 2.5G, 10G, 25G, 40G, 100G, 200G, 400G and 800G, among which 5G fronthaul oriented optical transceivers are extensively applied in optical fibre direct connection, passive WDM, active WDM/OTN/SPN, semi-active WDM access and other scenarios. In recent years, YOFC has been actively researching and developing next-generation data center-oriented optical modules, aiming to provide customers with more accurate, professional and comprehensive services.

Synthetic Quartz Material

YOFC independently owns synthetic quartz related technologies and can provide ultra-pure and fluorine-doped quartz liners, quartz ingots and quartz sheets. With excellent properties such as ultra-high purity and high UV and IR transmission, the products are suitable for applications such as optical fibre communication, optics, illumination and semiconductor components. 

Product Promotion Event 

At the booth, YOFC held a promotion event for special products around the themes of industrial lasers, data centers and optical fibre sensing, and introduced the latest technical progresses achieved by YOFC in using PCVD process to manufacture rare-earth-doped fibres and communication-oriented Faraday rotators, all-optical data center optical interconnect solutions, special product solutions for industrial lasers, and automotive optical component solutions, demonstrating YOFC's powerful platform, advanced technology, and comprehensive ability of providing customers with one-stop solutions. The product promotion event attracted a larger number of visitors and received overwhelming responses.
