an optical module

Abstract

The invention discloses an optical module. The optical module comprises an optical transceiving module, a casing and tail fibers; the optical module is provided with a single fiber interface; the tail fibers comprise a circulator, an optical cable, a first connector, a second connector and a third connector; the circular, the first connector and the second connector are arranged inside the casing; the optical cable and the third connector are arranged outside the casing. The optical module is provided with the single optical fiber interface and is of an single fiber interface structure; transmitting and receiving of an optical signal can be realized by using one optical fiber, thereby the service efficiency and the transmission bandwidth of the optical fibers can be improved, high-speed transmission can be realized, one half of optical fiber resources are saved, the cost of the system is greatly reduced, and the reliability of the system is improved; meanwhile, the complexity of network cabling of the optical module also can be reduced, so that the optical module is simple in structure and compact and small in size, and application of the optical module in a high-density integrated communication system is facilitated.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to an optical module. Background technique [0002] An optical transceiver module, referred to as an optical module, is a standard module used in equipment in the field of optical communication. This module is generally used as a standard accessory for optical routers and other equipment. In recent years, as users have higher and higher requirements for bandwidth and the popularity of fiber-to-the-home, etc., the optical module market has grown by leaps and bounds. [0003] Existing optical modules usually have a dual-fiber optical interface structure, which usually leads to low fiber usage efficiency, low transmission bandwidth, and an uncompact structure of the optical module. In optical fiber communication, the cost of optical fiber occupies a large proportion in the total cost. If the use of the existing optical fiber can be changed and a single optical f...
