Abstract: An optical component includes a first laser having a first light outlet and a second light outlet, a second laser having a third light outlet and a fourth light outlet, a first lens, a second lens, and an optical multiplexer. The first light outlet is configured to emit a first light beam. The second light outlet is configured to emit a second light beam. The third light outlet is configured to emit a third light beam. The fourth light outlet is configured to emit a fourth light beam. The first lens is configured to separately collimate the first light beam and the second light beam, and emit a first collimated light beam and a second collimated light beam. The second lens is configured to separately collimate the third light beam and the fourth light beam, and emit a third collimated light beam and a fourth collimated light beam.

Abstract: An optical component includes at least one optical sub-assembly, including a laser, a first lens located on a light emergence side of the laser, and an optical fiber array located on a light emergence side of the first lens. The laser has a first light outlet configured to emit a first light beam and a second light outlet configured to emit a second light beam. The first lens is configured to: transmit the first light beam and emit a first converged light beam, ransmit the second light beam and emit a second converged light beam, and transmit the first converged light beam and the second converged light beam to the optical fiber array. A first optical fiber of the optical fiber array is configured to receive the first converged light beam, and a second optical fiber of the optical fiber array is configured to receive the second converged light beam.
