Abstract

The invention discloses a BIDI device, an optical module and a production method. The BIDI device comprises a wavelength division multiplexer, a first optical device and a second optical device; one of the first optical device and the second optical device is an optical transmitter, and the other one is an optical receiver; the wavelength division multiplexer comprises a first optical port, a second optical port, a third optical port, a first collimation unit and a filter. The first collimation unit is arranged on one side, deviating from the first optical port, of the filter, and the filter can receive parallel light from the first lens unit; the first optical port is coupled and fixed with the first optical device, the second optical port is in optical path connection with the second optical device, the third optical port is used for receiving external light or emitting light, and the included angle A between the plane normal of the filter and the optical axis of the parallel light is smaller than or equal to 5 degrees. The BIDI device, the optical module and the production method have the advantages of being small in size and large in wavelength division density.

Description

technical field [0001] The present application relates to the field of optical communication, in particular to a BIDI device, an optical module and a production method. Background technique [0002] In the prior art, a pigtailed optical transceiver (hereinafter referred to as a BIDI device) requires an external wavelength division multiplexer (hereinafter referred to as a WDM component), such as figure 1 As shown, three optical fibers 110' need to be drawn from both sides of the WDM component 100' to connect the optical transmitter 200', the optical receiver 300' and the port 190', and the three optical fibers 110' are fused in the WDM component 100'. process, and the optical fibers 110' need to be matched, so a long tapered region is required, which leads to a long length of the WDM component 100' itself to meet the process requirements; in addition, the bending of the optical fiber 110' The diameter is limited. In the current technical field, the minimum bending diameter ...
