Claim 0:
1. An optical communication device, comprising a first optical transmitting device, a second optical transmitting device, a first optical receiving device, a second optical receiving device, an optical path component, and an optical fiber adapter, the optical path component comprising a primary light filter, a secondary light filter, a third light filter, a fourth light filter, and a first lens disposed between the third light filter and the fourth light filter, wherein
a light source and a first converging lens are packaged in each of the first optical transmitting device and the second optical transmitting device, and the first converging lens is configured to: converge a first light beam emitted by the light source, and provide a converged first light beam to the optical path component;
the optical path component is configured to: combine converged first light beams from the first optical transmitting device and the second optical transmitting device, and send a combined light beam to the optical fiber adapter;
the optical path component is further configured to:
receive a second light beam from the optical fiber adapter,
send a light beam of a first wavelength in the second light beam to the first optical receiving device by transmitting the light beam of the first wavelength through the primary light filter; and
send a light beam of a second wavelength in the second light beam to the second optical receiving device by reflecting the light beam of the second wavelength from the primary light filter to the secondary light filter and then reflecting the light beam of the second wavelength from the secondary light filter to the second optical receiving device;

a second converging lens and a photoelectric detection element are packaged in each of the first optical receiving device and the second optical receiving device, and the second converging lens is configured to converge the second light beam received by the optical path component, and provide a converged second light beam to the photoelectric detection element;
the third light filter is disposed on a transmission path of a light beam transmitted by the first optical transmitting device and on a transmission path of a light beam transmitted by the second optical transmitting device;
the fourth light filter is disposed on a transmission path of the second light beam from the optical fiber adapter;
the first lens is configured to converge a light beam from the third light filter, and provide a converged light beam or a parallel light beam to the fourth light filter.
