Abstract

A single-fiber bidirectional component comprises a substrate, a tube core sleeve, a receiver, an adapter, a laser device and an optical filter. The laser device is connected with the tube core sleeve, the optical filter is arranged in the substrate, a first connecting hole and a second connecting hole which are coaxial are arranged on the substrate, the tube core sleeve is inserted into the first connecting hole, the inner diameter of the first connecting hole is larger than the outer diameter of the tube core sleeve, and the adapter is inserted into the second connecting hole. Light emitted from the laser device is coupled by the optical filter and enters the adapter, and light entering the adapter is reflected by the optical filter and further enters the receiver. In a packaging process of the single-fiber bidirectional component, coupling adjustment is carried out at first so as to obtain proper optical power, and then packaging is carried out. During coupling adjustment, the laser device can be longitudinally adjusted while the adapter is transversely adjusted due to the fact that the inner diameter of the first connecting hole is larger than the outer diameter of the tube core sleeve, the adapter does not need to be longitudinally adjusted, coupling of a receiving end is unaffected, receiving coupling can be realized easily, and packaging yield is high.

Description

【Technical field】 [0001] The invention relates to the field of optical fiber communication, in particular to a single-fiber bidirectional component and a packaging method thereof. 【Background technique】 [0002] The single-fiber bidirectional assembly (BOSA) is the core device of modern optical communication. It is a photoelectric conversion device integrating transmitting and receiving. The transmission rate of single-fiber bidirectional components is from 155M / s to 10G / s, the transmission distance is from 10 kilometers to more than 100 kilometers, and the wavelength used is from 1260nm to 1620nm, which has been widely used. However, in the packaging of traditional BOSA, vertical adjustment adapters are often used for transmission coupling, resulting in low yields when receiving coupling. 【Content of invention】 [0003] Based on this, it is necessary to provide a single-fiber bidirectional component with high packaging yield and a packaging method thereof. [0004] A si...
