Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In addition, in all the drawings for explaining the embodiment, the same reference numerals are assigned to the members having the same functions, and repeated description thereof will be omitted. In addition, the figure shown below is only a figure explaining the Example of embodiment, and the scale of a figure and this Example description does not necessarily match.

[0025] figure 1 It is a perspective view of the optical module 1 according to the embodiment of the present invention. The optical module 1 uses the optical transmitting assembly (TOSA) built in the box body 10 to output optical signals according to the electrical signals input from the outside, and uses the optical receiving assembly (ROSA) to output electrical signals based on the optical signals input from the outside. . The optical transmitting unit (TOSA) and the optical receiving unit (ROSA) are ...

Abstract

An optical module includes: a housing including an optical port in one of side surfaces opposite each other and an electric port in the other; an optical fiber disposed inside the housing and connected to the optical port; and an optical subassembly disposed inside the housing, optically connected to the optical fiber, and electrically connected to the electric port. The optical fiber is disposedso as to wind around the optical subassembly at least one turns in a plan view.

Description

technical field [0001] The present invention relates to optical modules. Background technique [0002] An optical module is known, which incorporates optical components such as a Transmitter Optical SubAssembly (TOSA) and a Receiver Optical SubAssembly (ROSA), and transmits and / or receives optical signals. [0003] Japanese Unexamined Patent Application Publication No. 2011-033644 discloses an optical module having a bracket from which an optical fiber optically connected to an optical module is wound and drawn out. [0004] In the box of the optical module, there are cases where optical fibers for transmitting optical signals are arranged. Once the bending radius of the optical fiber is reduced below the minimum allowable radius, it will cause loss of optical signal intensity, light reflection, etc., and even cause deterioration of transmission characteristics. However, as optical modules have been miniaturized in recent years, there has been a need to house the optical f...
