Problems solved by technology

[0002] In the prior art, the optical transceiver device needs to emit beams and receive beams at the same time, and different beams are transmitted through different optical fibers. However, when there are many light sources and photoelectric conversion components, the optical transceiver device needs to use multiple optical fibers, or multiple Optical couplers, optical splitters, etc. increase the volume of optical transceivers

Embodiment Construction

[0012] see figure 1 The optical transceiver device 100 provided by the first embodiment of the present invention includes a light source module 12, a photoelectric conversion module 14, only one optical fiber 16, a lens module 18 and an optical splitter 20 (also referred to as a splitter). Wave multiplexer, WDM, wavelength divisional multiplexer).

[0013] The light source module 12 is used to emit the first light beam L1, and the photoelectric conversion module 14 is used to receive the second light beam L2. The first light beam L1 and the second light beam L2 are in opposite directions, for example, the first light beam L1 belongs to a down flow, and the second light beam L2 belongs to an up flow. Generally, the wavelengths are not equal to each other, for example, the first light beam L1 has a wavelength of 1300 nm, and the second light beam L2 has a wavelength of 1550 nm. The optical fiber 16 is used to transmit the first light beam L1 and the second light beam L2.

Abstract

The invention provides a light collecting-transmitting device. The light collecting-transmitting device comprises a light source module, a photovoltaic conversion module, only one optical fiber, a camera lens module and a light way divider. The light source module is used for sending a first light beam, the photovoltaic conversion module is used for receiving a second light beam, and the optical fiber is used for transmitting the first light beam and the second light beam. The camera lens module comprises a containing part, wherein the containing part is provided with a first lens part, a second lens part and a third lens part, and the first lens part, the second lens part and the third lens part are respectively in optical alignment with the light source module, the photovoltaic conversion module and the optical fiber. The light way divider is arranged in the containing part to guide the first light beam to enter the optical fiber and guide the second light beam which is transmitted from the optical fiber to the photovoltaic conversion module.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to an optical transceiver. Background technique [0002] In the prior art, the optical transceiver device needs to emit beams and receive beams at the same time, and different beams are transmitted through different optical fibers. However, when there are many light sources and photoelectric conversion components, the optical transceiver device needs to use multiple optical fibers, or multiple Optical couplers, optical splitters, etc. increase the size of the optical transceiver. Contents of the invention [0003] In view of this, it is necessary to provide an optical transceiver device with a small number of optical fibers and a small volume. [0004] An optical transceiver includes a light source module, a photoelectric conversion module, only one optical fiber, a lens module and an optical splitter. The light source module is used to emit the first light beam, the p...
