Abstract
An optical module is provided with a ferrule an optical fiber which penetrates a center thereof along an axis direction of the ferrule, a member inserted with the ferrule, a sealed container connected to the member and having an optical system which optically couples to the optical fiber, and a resin portion encapsulating the member and the sealed container. A communication path includes a first communication passage between the ferrule and the member, a space where the optical system and the optical fiber confront each other, and a second communication passage between the ferrule and the member, where the first and second communication passages are mutually independent.

An optical module comprising:
- a ferrule an optical fiber which penetrates a center thereof along an axis direction of the ferrule;
- a member inserted with the ferrule;
- a sealed container, connected to the member, having an optical system which optically couples to the optical fiber;
- a resin portion encapsulating the member and the sealed container;
- and
- a communication path including a first communication passage between the ferrule and the member, a space where the optical system and the optical fiber confront each other, and a second communication passage between the ferrule and the member, said first and second communication passages being mutually independent.
An optical module producing method for producing an optical module which is provided with a ferrule an optical fiber which penetrates a center thereof along an axis direction of the ferrule, a member inserted with the ferrule, a sealed container connected to the member and having an optical system which optically couples to the optical fiber, a resin portion encapsulating the member and the sealed container, and a communication path including a first communication passage between the ferrule and the member, a space where the optical system and the optical fiber confront each other, and a second communication passage between the ferrule and the member, said first and second communication passages being mutually independent, said optical module producing method comprising the step of:
- (a) placing at least the ferrule and the member within a mold;
- and
- (b) supplying a gas to the first communication passage and exhausting the gas from the second communication passage when supplying melted resin into the mold to form the resin portion.
