摘要： This application provides a communication device, a communication system, and an optical module, which have a high-rate signal transmission capability, relatively low costs, and a low heat dissipation requirement each. The communication device includes a processing module, at least one optical module, and at least one connection apparatus. Each of the at least one optical module is connected to the processing module by using a corresponding connection apparatus. The processing module is configured to: provide an electrical signal for each optical module, or receive an electrical signal provided by the optical module. Each optical module is configured to: convert the electrical signal provided by the processing module into an optical signal and then send the optical signal, or convert a received optical signal into an electrical signal and then provide the electrical signal for the processing module. The connection apparatus corresponding to each optical module is configured to: transmit the electrical signal provided by the processing module to each optical module, or transmit the electrical signal provided by each optical module to the processing module. The connection apparatus includes a coaxial cable or a flexible printed circuit, and each optical module has no optical digital signal processing (oDSP) sub-assembly or clock signal recovery (CDR) sub-assembly.
