Optical transceiver assembly

An optical transceiver assembly, comprising a first cavity, a second cavity, and a set of wavelength division multiplexers (WDMs) including a first WDM and a second WDM, wherein:

• the first cavity is air tight, and comprises at least two optical receivers, the at least two optical receivers being configured to receive light of different wavelengths, respectively;
• and
• the second cavity is air tight, and comprises at least two optical transmitters, the optical transmitters being configured to emit light of different wavelengths, respectively, wherein
• wavelengths of light received by the at least two optical receivers are different from wavelengths of light emitted by the at least two optical transmitters, and each optical receiver and each optical transmitter correspond to different WDMs in the set of WDMs, respectively,
• the first cavity and the second cavity are connected by a common cavity wall,
• in the first cavity, ceramic is disposed on a cavity wall on a side far away from the first WDM, metal pins are disposed on the ceramic in the first cavity, wherein the metal pins are implanted in the first cavity through a vias in the ceramic and are connected to one end of a lead disposed in the first cavity, and the other end of the lead in the first cavity is connected to the optical receiver;
• and
• in the second cavity, ceramic is disposed on a cavity wall on a side far away from the WDM corresponding to the optical transmitter, metal pins are disposed on the ceramic in the first cavity, the metal pins are implanted in the second cavity throug a vias in the ceramic and are connected to one end of a lead disposed in the second cavity, and the other end of the lead in the second cavity is connected to the optical transmitter;
• the first WDM corresponds to one of the at least two optical receivers and is configured to:
• separate, from a light emitted from an optical fiber, a light having a wavelength recievable by the optical receiver corresponding to the WDM, transmit the light to the optical receiver corresponding to the first WDM, and reflect a light having the other wavelengths;
• and
• the second WDM corresponds to one of the at least two optical transmitters and is configured to:
• transmit a light having a wavelength emitted by the optical transmitter corresponding to the second WDM;
• and, wherein the optical transceiver assembly further comprises:
• an optical reflection component, configured to totally reflect the light transmitted or reflected from the WDMs.
