光路科技发布全国产化TSN变电站交换机，助力电力通信自主可控升级

Core Viewpoint - Fiberroad has successfully developed and tested two new products, the FR-TSN3000 and FR-TSN6000, which are fully domestically produced and controllable substations network switches, aimed at enhancing the communication network for smart substations [1][3]. Group 1: Product Features - The FR-TSN3000 and FR-TSN6000 utilize a "domestic + TSN" design approach, focusing on critical business scenarios such as GOOSE and SV, to improve the predictability and stability of secondary system communications in the power sector [3]. - Both products are built with entirely domestic components, ensuring information security and supply chain stability, and comply with the latest technical specifications for Ethernet switches in the power industry [3][4]. - The switches are optimized for harsh electromagnetic interference and complex power conditions, supporting 110V/220V DC input with a ±20% voltage fluctuation tolerance, as well as 220V AC input [3]. Group 2: Testing and Compliance - The FR-TSN3000 and FR-TSN6000 have passed the national grid system network access tests and received certification from the China Electric Power Research Institute [4]. - They have also undergone information security testing and component selection analysis by the Ministry of Industry and Information Technology's Fifth Research Institute, confirming their reliability and consistency [4]. Group 3: Application and Industry Impact - The products adhere to the DL/T 860 (IEC 61850) modeling and communication framework, allowing for unified modeling and management of substation equipment, and enabling fine control over critical messages like GOOSE and SV [4]. - The release of these TSN switches signifies a maturation in the integration of domestically produced controllable switches with TSN deterministic Ethernet technology within the power system [4]. - Fiberroad aims to continue advancing domestic industrial Ethernet technology in collaboration with the new power system, providing safer, more reliable, and sustainable network infrastructure for the power industry [4].
