Standard Study & Alliance Participation

 
Part 1   Analysis of International Standards
 
1、Updated standards for Ethernet
 
The IEEE P802.3cg Draft version 3.4 has been approved by IEEE-SA.
IEEE 802.3cg defines a physical layer interface specification for data transmission of 10 Mb/s by using a single twisted-pair system, and supports power delivery via PoDL technology.
 
2、Standards for high-speed transmission

From a global perspective, since the birth of high-speed interconnect transmission standards, the transmission rate has been continuously improved, from the initial 2Gbps, 3.2Gbps, 10Gbps, to 100Gbps. In September 2018, IEEE802.3 Work Group released the 200Gbps standards, and the Ethernet standards for 400Gbps rate is under development. In the application of 5G communication systems, the transmission and exchange of big data requires that the rate of high-speed interconnect products must reach 200Gbps or even 400Gbps.
 
3、Standards for railway locomotives 

Although the domestic standards involve network communication data cables, only including the performance requirements for CAT5 with a bandwidth of 100MHz, which supports data transmission of up to 1000Mbps. 
With the development of mobile communications, especially with the development of 5G, CAT6A (or above) cables must become the mainstream. However, there are no provisions for cables above CAT5e in the standards for railway locomotive cables.

 
Part 2   Participation in the Preparation of White Papers & Standard Development
 
On May 28 2018, the meeting for preparation of the "White Paper for POE Technology and Application" organized by SAC/TC 28/SC 25 was successfully held in Beijing. Zhejiang Zhaolong Interconnect Technology Co., Ltd. (hereinafter referred to as Zhaolong) attended the meeting and undertook the task of writing chapters in the white paper about elements of system design, performance indicators, product selection and configuration, etc. The white paper was released in October of that year.

In February 2019, Zhaolong was invited to participate in the "White Paper for Data Center Network System Technology" organized by China Data Center Committee (CDCC) of China Association for Engineering Construction Standardization (CECS). 

In April 2019, Zhaolong was invited to participate in the "White Paper for 400G Network Cabling Technology" organized by the Cablingteam (CTEAM) of China Association for Engineering Construction Standardization (CECS).

 
Part 3   Ethernet Alliance Participation
 
Zhaolong Interconnect participates in the New In-Vehicle High-Speed Network (NIVN) Working Group of China Industry Innovation Alliance for the Intelligent and Connected Vehicles  (CAICV).

The purpose of the Working Group is to promote the ecological development of the domestic new in-vehicle high-speed network. While carrying out the new in-vehicle high-speed network technology and testing standardization, the Working Group will promote the innovation and prospective study,   to improve product quality and consistency, carry out testing verification, promote industrial cooperation and industrial research, strengthen academic exchanges and enhance the communication and cooperation with the related domestic and international standardization institutes.

In addition to the domestic working group of In-vehicle Ethernet, Zhaolong Interconnect also participates in the research of In-vehicle Ethernet technology by Open Alliance.

SPE-Industrial Partner Network is led by companies such as HARTING, TE, HIROSE, WürthElektronik, etc.. It is an organizational alliance that promotes the development of the Industrial Internet of Things (IIoT) with Single-pair Ethernet technology as the key technology.

 Zhaolong Interconnect is one of the senior members of SPE-Industrial Partner Network. Single Pair Ethernet (SPE) is an Ethernet transmission technology using only a pair of copper wires. In addition to data transmission via Ethernet, SPE can also supply power to terminal devices through PoDL (Power over Data Lines). SPE opens up new possibilities and applications for Industrial Ethernet and it will be one of the key technologies of the Internet of Everything (IoE). Zhaolong, as the promoter of SPE technology, will lead the technology trend!
