Abstract
In a bidirectional optical communications module capable of all-dual-mode communications using a single optical fiber, interference due to internally scattered light is reduced by forming a diverging area on a periphery of a transmission lens and providing a thin film reflection mirror which collects incoming light. A inexpensive, compact bidirectional optical communications module can be offered with reduced interference between outgoing and incoming light, especially, interference due to internally scattered light.
