Combo port switching circuit

Abstract

The invention belongs to the technical field of network communication equipment and discloses a Combo port switching circuit, which comprises a control IC, a trigger module, a high-speed switching device, an optical module interface and an RJ45 electric port. The trigger module is connected with the control IC. The control IC is connected with the high-speed switching device, and the high-speed switching device is respectively connected with the optical module interface and the RJ45 electric port. The trigger module inputs a photoelectric port switching signal to the corresponding pin of the control IC, A control IC receives and processes the photoelectric port switching signal, A control signal is output which controls the high-speed switching device to turn on the channel between the control IC and the optical module interface and to turn off the channel between the control IC and the RJ45 electrical port or the channel between the control IC and the optical module interface and to turn on the channel between the control IC and the RJ45 electrical port. The invention realizes the switching of the optical port and the electric port, and improves the flexibility of the port configuration.

Description

technical field [0001] The invention belongs to the technical field of network communication equipment, and in particular relates to a Combo port switching circuit. Background technique [0002] With the rapid integration of industrialization and informatization, industrial intelligent manufacturing is developing rapidly, and the demand for 100M or Gigabit Ethernet communication in industrial sites is increasing. The port forms of Ethernet communication include electrical ports and optical ports, and most switch chip port outputs The form can be configured. The general practice of switch manufacturers is to uniformly configure the products as electrical port output or as optical port output before leaving the factory. That is, the port form is fixed, and customer needs often change. This approach is not conducive to product The derivation and expansion of products will cause a wide variety of products, which will cause inconvenience to production and processing and is not co...
