Document Type and Number:
Japanese Patent JPH05507836
Kind Code:
A
Abstract:
A system is provided implementing an extremely high speed link allowing selection of either twisted pair (or like media) and fiber media in to provide a high speed multimedia local area network. A high speed transmission link for twisted pair, coaxial cable media or the like includes a transmitter with a conversion device for receiving fiber optic data interface signals intended to drive a fiber optic data interface and for converting these fiber optic data interface signals into high speed transmission link signals of a form suitable to drive a twisted pair medium. A receiver is provided and includes a reconversion device for regenerating the signal received from the twisted pair medium back to an adequate signal level. The transmitter conversion device includes a buffer cooperating with an equalizer and a filter for forming the high speed transmission link signal. The equalizer provides frequency domain compensation for the characteristics of the twisted pair medium. The filter rejects signals outside a band of data signaling. The receiver reconversion device includes a filter connected to said twisted pair medium to reject signals outside a band of data signaling, a buffer for regenerating the signal received from the twisted pair and a low frequency restoration circuit which employs a decision feedback technique for the compensation of the media coupling circuit's low frequency response.
