10Mbps 100Mbps A OPTICAL DATER RELAY TRANSMISSIVE DEVICE FOR COMMON USING IN TRANSMISSION SPEED 10Mbps AND 100Mbps CONDITIONS OF THE ETHERNET

摘要

The present invention relates to an optical relay transmission apparatus that can be used in common at 10Mbps and 100Mbps transmission speeds of Ethernet, and includes a UTP cable connection part connected to a LAN card, an optical transmission / reception part connected to an optical cable, a physical layer, a controller, a status display part, a power supply. In the optical relay transmission device which is composed of connection part, voltage regulator, oscillator, DIP switch and converts UTP cable signal and optical signal to extend the limited transmission distance of Ethernet to perform long-distance transmission of data, the present invention has a physical layer. It is equipped with a common physical layer that can be applied to both general and optical networks, and automatically detects the transmission speed of 10Mbps and 100Mbps and automatically sets the status. Switch controller with half / full duplex auto selection. Characterized in that provided. The present invention can be applied to various network environments as a single device, which is convenient for product selection, and even after the installation of the device, it is convenient for the post-maintenance maintenance because there is no need to change equipment or operate DIP switches even if the network environment changes It works.
