Abstract

Provided is an electrooptic conversion module, which can replace electronic parts more economically in case a malfunction occurs or in case an improvement is needed. In the electrooptic conversion module (1), a plurality of split units such as an optical signal transmit / receive unit (201) for converting an electric signal inputted into an optical signal to propagate in an optical waveguide (2) orfor converting an electric signal inputted into an optical signal to output the converted signal to the optical waveguide (2), an amplifying unit (202) and a communication control unit (203) are so fitted and retained in a fitting unit (120) to be connected with a cover member (111) exposed to the outside, that the terminal portions in the fitting portion (120) and the electrode portions of thosesplit units contact with each other.

Description

technical field [0001] The invention relates to an electro-optic conversion module. Background technique [0002] Conventionally, an electro-optic conversion module using a planar lightwave circuit (PLC: Planar Lightwave Circuit) has been known in optical communications such as fiber to the home (FTTH: Fiber To The Home). This type of electro-optical conversion module is equipped with components for driving vertical cavity surface emitting laser (VCSEL: Vertical-Cavity Surface-emitting Laser), laser diode (LD: Laser Diode), photodiode (PD: Photo Diode), LD element, etc. Various large-scale integrated circuits (LSI: Large Scale Integration) of a driver or an amplifier for amplifying signals are arranged on a PLC board. [0003] For example, Non-Patent Document 1 discloses, as a technique for the electro-optical conversion module described above, the technique of making high-precision switching between semiconductor optical elements such as laser diodes and photodiodes and op...
