TRX E1-10/100Base-T developed by Hengguang Technologies, employs the clarity E1 transmission channel in accordance with ITU-T G.703 advice and IEEE802.3 standard with independent intellectual property. It is a kind of remote transmission equipment transmitting 10 Base-T data. With an independent structure, TRXE1-10Base-T can transmit 10Base-T data through E1 channels and extend work distance of the interface between two Ethernets through E1 channels such as optical fiber, microwave DDN nets and so on. It can use the existing communication network structures and interfaces efficiently without impropriating optical fiber core or additional equipment.
