Description
Technical field
The present invention relates to the communications field, relate to a kind of service transmitting/receiving device and method specifically.
Background technology
Rapid development of Internet makes the influence of network extend in each corner of social life.The application of the Internet is more and more, and people's life more and more be unable to do without network, and network is the important effect of play more and more in people's life, and therefore, people also have more and more higher requirement to the stable of network with reliability.The of short duration system failure of the network equipment brings very big loss all can for operator, enterprise and user, and high reliability has become the primary demand of telecommunication apparatus.
In order to reach the high reliability of telecommunication apparatus, must realize that device systems can continuous service when these equipment break down.In actual applications, a kind of major technique that realizes the equipment operation high reliability is exactly that important module to system backs up, it also is a module in running order (this module is called the main module of using), another module is in stand-by state (this module is called spare module), when the master who is working is broken down with module, switch to spare module at once to guarantee professional normal operation at line service.
At above-mentioned active and standby situation with the module back-up job, send professional uplink port to upstream plant and also have dual mode in actual applications: a kind of is that main port with module and spare module links to each other with upstream plant with link by active and standby respectively, and business is sent to upstream plant or module; Another kind be main with module and spare module pass through a common port and upstream plant, business is sent to upstream plant or module.Dual mode respectively has superiority, and preceding a kind of mode can realize active and standby backup with link, and a kind of mode in back only needs a link to link to each other with upstream plant or module, has saved cost, has made things convenient for the maintenance of circuit
For second kind of above-mentioned situation, in the application of optical network device system, can both link to each other with upstream plant by a uplink port in order to realize main business with module or spare module, prior art has adopted the method for optical splitter.
As shown in Figure 1, two modules A modules and the active and standby each other module of using of B module among the figure, A module and B module all comprise interface module U1 and optical module U2 respectively, and interface module U1 links to each other with optical module U2, and business datum is handled the back through interface module U1 and sent by optical module U2.The optical module of A module and B module links to each other with optical splitter respectively.
Suppose that in equipment running process, current A module is that the master uses module, in running order, the B module is a spare module, is in stand-by state.When sending data, the A module sends to optical splitter with the light signal of bearer service data, and the B module is not luminous, and optical splitter is with the optical signal replicating that receives and send to upstream plant; When receiving data, optical splitter will receive the optical signal replicating of business datum and send to the A module and the optical interface module of B module, in running order A module receives light signal, and this moment, spare module did not deal with received light signal owing to being in stand-by state.At this moment, the A module can normally be communicated by letter with upstream plant by optical splitter.After equipment active and standby switched with module, also be that the B module is mainly use module, in running order, the A module is a spare module, when being in stand-by state, according to top same reason, being in to lead and also can communicating by letter normally with upstream plant with the B module of state.
Though above-mentioned technology can realize active and standbyly communicating by letter with upstream plant by same port with module, also there are following shortcomings:
1. active and standby with module optical interface and the line complexity between the optical splitter, especially active and standbyly when many, be not easy to maintenance with module when such;
2. do not support a plurality of modules simultaneously luminous, require spare module when not working, not send light signal, otherwise main light signal generating with module is disturbed, thereby can not support all optical modules.
