Description
Technical field
The present invention relates to the alarm transmission methods and system of transmission, more particularly to a kind of high severity alarm transmission method, height
Fast photoelectric conversion device and system.
Background technology
High speed optoelectronic conversion equipment is typically that electric signal is converted directly into optical signal to be transmitted, specific to electric signal
Data, which are not made, to be parsed and changes, in this way could be by the cost control of high speed optoelectronic conversion equipment in acceptable range.However, not
Parsing is made to electrical signal data and change may result in some significant alarm signals and can not transmit, such as：Cable side failure, high-speed light
Electric conversion equipment failure itself and environment alarm etc..
For solution must not transmitting warning signal the problem of, the following two modes of generally use, one is parsing electric signal, carry
It after taking valid data therein, in addition being Resealed after warning information, is transmitted, still, in this way, is accused again later

Breath.It is difficult to be transferred directly to local side that various alarms at the far end, which occur, this brings difficulty to monitoring.Certainly this kind of alarm
The local side of transmission can parse the data flow of HD-SDI again, constitute a new frame format, warning information is arranged in it
In, such way is most apparent the disadvantage is that cost is too high.
No matter however, using which kind of above-mentioned mode, it is required for the transmission data in a manner of proprietary protocol, this is just obviously increased
The cost of high speed optoelectronic conversion equipment.
