METHOD FOR IMPLEMENTING PHOTOELECTRIC MUTEX, ETHERNET PHOTOELECTRIC MUTEX INTERFACE DEVICE AND NETWORK EQUIPMENT

摘要

A method for implementing photoelectric mutex, an Ethernet photoelectric mutex interface device, and network equipment are provided. The Ethernet photoelectric mutex interface device includes a channel switching module, a first Ethernet physical layer (PHY) chip, and a second Ethernet PHY chip. The channel switching module is connected to the first Ethernet PHY chip through a first interface and connected to the second Ethernet PHY chip through a second interface respectively, and is adapted to perform data transmission through the first Ethernet PHY chip and when a presence signal of an optical interface data transmission module is detected, perform data transmission through the second Ethernet PHY chip. Thus, a cost of equipment for implementing a photoelectric mutex function in an Ethernet is reduced, and a utilization rate of transmission resources is improved.
