In order to solve these potential problems, to the object of the invention is to overcome in prior art existing above-mentioned deficiency, providing that a kind of transmission performance is good, the cable module of long transmission distance.
Further aim of the present invention is to provide a kind of electrical connection variation, practical cable module.
In order to realize foregoing invention object, the technical solution used in the present invention is:
Based on a 100G cable module for CFP4 interface, comprise CFP4 interface, CDR receiver module, CDR sending module, MCU, cable interface,
Described CDR receiver module connects described cable interface and described CFP4 interface respectively, for receiving the first signal that described cable interface sends, this first signal is converted to the first processing signals by described CDR receiver module, and described first processing signals is sent to described CFP4 interface;
Described CDR sending module connects described cable interface and described CFP4 interface respectively, its secondary signal sent for receiving described CFP4 interface, this secondary signal is converted to the second processing signals by described CDR sending module, and described second processing signals is sent to described cable interface
Described MCU connects described CDR receiver module and described CDR sending module simultaneously, and it is for controlling the operation of described CDR receiver module and described CDR sending module.
Further, this first signal is converted to the first processing signals and refers to by described CDR receiver module, becomes the first processing signals after described first signal is carried out clock recovery operation;
This secondary signal is converted to the second processing signals and refers to by described CDR sending module, becomes the second processing signals after described first signal is carried out clock recovery.
Further, described cable interface is copper cable interface.
