Optical connector module

An optical connector module for connecting between a first device that outputs electrical information signals and a second device that receives optical information signals, comprising:

• a first connector module for connecting to the first device, for being electrically detachable, and for converting the electrical information signals from the first device into the optical information signals;
• an optical fiber cable having a first end disposed to face the first connector module, for transmitting the optical information signals to a second end;
• and
• a second connector module installed at the second end of the optical fiber cable for guiding the connection of the optical fiber cable to the second device;
• wherein the first connector module includes:
• a light emitting unit comprising electrical terminals for electrically connecting to the first device and inputting the electrical information signals, light emitting devices for emitting light beams according to the electrical information signals, and a driving portion for driving the light emitting devices;
• and
• a first connector for connecting the light emitting unit and the optical fiber cable so that the light emitting unit and the optical fiber cable are aligned to each other while maintaining a predetermined distance, and guiding connection of the optical fiber cable to the first device;
• and
• wherein the light emitting unit further comprises a multiplexer provided between the electrical terminals and the driving portion for selecting one electrical signal among the electrical information signals according to a selection control signal, and wherein the second device comprises a demultiplexer corresponding to the multiplexer.

An optical connector module for connecting between a first device that outputs optical information signals and a second device having a port for receiving electrical information signals, comprising:

• a first connector module;
• an optical fiber cable, a first end of which is coupled to the first connector module for transmitting the optical information signals to a second end of the optical fiber cable, wherein the first connector module couples the optical fiber cable to the first device;
• and
• a second connector module for being connected to the second device while being electrically detachable and for converting the optical information signals transmitted through the optical fiber cable into the electrical information signals and supplying the electrical information signals to the second device;
• wherein the second connector module includes:
• a light receiving unit comprising light receiving devices for receiving the optical information signals transmitted through the optical fiber cable and outputting corresponding information signals, an amplifier for outputting amplified signals based on the information signals, and electrical terminals, electrically connected to the second device, for transmitting the electrical information signals in accordance with the amplified signals;
• and
• a second connector for connecting the light receiving unit and the optical fiber cable so that the light receiving unit and the optical fiber cable can be aligned to each other while maintaining a predetermined distance;
• and
• wherein the light receiving unit further comprises a demultiplexer provided between the amplifier and the electrical terminals, wherein the first device comprises a multiplexer corresponding to the demultiplexer and where the multiplexer selects one electrical information signal among the electrical information signals according to a selection control signal.
