Optical communication module

An optical communication module comprising:

• a platform configured to have a plurality of through-holes each of which vertically passes through the platform and is provided in parallel with a direction of light input or output through an optical line;
• an optical receiver configured to be provided on the platform and include at least one light-receiving element and an amplifier for converting current generated by the light-receiving element into voltage and then amplifying the voltage;
• an optical transmitter configured to be provided on the platform and include at least one light-emitting element;
• a plurality of optical filters configured to have different wavelength pass bands and to be provided on one surface of the platform to correspond to the through-holes, transmit light from the light-emitting element to an optical line, and transmit light input through the optical line to the light-receiving element;
• an optical line focusing lens which focuses light passing through the optical filters and transmits the focused light to the optical line;
• and
• an optical receiver focusing lens configured to be provided between the light-receiving element and the optical filter,
• wherein one of the optical receiver and the optical transmitter is provided on one surface of the platform on an opposite side of the optical line with the optical filters interposed therebetween, and the other is provided on the other surface of the platform to correspond to the through-hole, and
• a first groove on which the optical line focusing lens is placed is formed on one surface of the platform, and a second groove for receiving the amplifier together with the light-receiving element or the light-emitting element is formed on the other surface of the platform.

An optical communication module comprising:

• a platform configured to have a plurality of through-holes each of which vertically passes through the platform and is provided in parallel with a direction of light input or output through an optical line;
• and
• a plurality of optical filters configured to have different wavelength pass bands and to be provided on one surface of the platform to correspond to the through-holes;
• and
• a lens configured to be provided between the optical line and an optical filter closet to the optical line among the optical filters,
• wherein a plurality of light-receiving elements or light-emitting elements are provided on the other surface of the platform to correspond to the through-holes,
• at least one of the optical filters includes a block filter configured to block specific wavelength band to thereby reduce optical crosstalk, and
• a first groove on which the lens is placed is formed on one surface of the platform, and a second groove for receiving the light-receiving element or the light-emitting element is formed on the other surface of the platform.

An optical communication module comprising:

• a platform configured to have a through-hole therein which vertically passes through the platform;
• an optical receiver configured to include a light-receiving element provided on the bottom surface of the platform to correspond to the through-hole and an amplifier for converting current generated by the light-receiving element into voltage and then amplifying the voltage;
• an optical transmitter configured to include a light-emitting element provided on the top surface of the platform;
• an optical filter configured to be provided on the top surface of the platform to correspond to the through-hole, to transfer output light from the light-emitting element to the optical line, and to transfer input light received via the optical line to the light-receiving element;
• an optical line focusing lens configured to be provided between the light-emitting element and the optical filter;
• an optical isolator configured to be provided between the light-emitting element and the optical filter;
• and
• an optical receiver focusing lens configured to be provided between the light-receiving element and the optical filter,
• where a first groove on which the optical line focusing lens or the optical isolator is placed is formed on the top surface of the platform, and a second groove for receiving the light-receiving element and the amplifier is formed on the bottom surface of the platform.
