LINE CARD, OPTICAL MODULE AND OPTICAL NETWORK DEVICE

摘要

Provided in an embodiment of the present invention are a line card, optical module and optical network device, the line card comprising: a mainboard, a panel, an optical module and a wavelength division multiplexer/demultiplexer; the optical module comprises: at least one electrical interface and at least one optical interface; the wavelength division multiplexer/demultiplexer comprises: a first interface and a second interface; the panel is disposed on the edge of the mainboard; the electrical interface is electrically connected to the mainboard; the optical interface faces a direction parallel to the mainboard and pointing from the edge of the mainboard to the interior of the mainboard, and is connected to the first interface; the wavelength division multiplexer/demultiplexer is disposed on the mainboard; the second interface is connected to a main optical fiber; and the main optical fiber is used to connect an optical network device at a transmitting terminal to an optical network device at a receiving terminal. The technical solution in the embodiment of the present invention improves space usage efficiency of an optical network device, and reduces the number of optical fiber connecting wires outside the optical network device, thus reducing management difficulty.
