BANDWIDTH-ADJUSTABLE OPTICAL MODULE AND SYSTEM

摘要

The present invention relates to the field of communications technologies, and in particular, to a bandwidth adjustable optical module. A circuit board of the optical module is provided with a first electrical interface and a second electrical interface, a first optical port and a second optical port, and an optical transceiver assembly; the first electrical interface is configured to connect an electrical interface of a board or a second electrical interface of another optical module, and the second electrical interface is configured to connect a first electrical interface of another optical module; the first optical port is configured to connect an optical transmission device or a second optical port of another optical module, and the second optical port is configured to connect an optical receiving device or a first optical port of another optical module; and the optical transceiver assembly multiplexes downstream light and demultiplexes upstream light. The optical module provided in solutions of the present invention can be flexibly combined with another optical module, enabling flexible and gradual upgrade of an optical module bandwidth according to a user requirement by using various combination manners.
