Chip, which is converted into realizing with the low and high level of intercom set altogether, realizes lightning protection requirement to the filtration treatment protection of signal, protects
Protect equipment internal circuit.
The alarm module further includes grounding pin, and the optical communication equipment where SFP mouthfuls can be with by grounding pin
Judge the optical port insert be normal SFP optical module or this kind of External Alarm Module, in addition also can use the different addresses I2C
Distinguish the optical port insert be normal SFP optical module or alarm module (optical module has the specific address I2C), to realize optical port
Multiplexing.
The isolating chip can be common isolating chip, or the isolated core with isolation voltage output function
Piece.When two or more described isolating chips are arranged in the quantity according to alarm signal, user demand, alarm module,
Isolating chip with isolation voltage output function and common isolating chip can be set simultaneously.
A kind of alarm device using SFP mouthfuls is also disclosed in the utility model, and above-mentioned alarm module is mounted on optic communication and is set
The SFP port communications of standby upper use, the alarm module and optical communication equipment connect；Optical communication equipment includes power module, described
Power module is powered by the described SFP mouthfuls extended chip, the isolating chip to the alarm module；Optical communication equipment
Including controlling chip, the control chip is connect with described SFP mouthfuls by I2C.
Turn extended chip by I2C using SFP mouthfuls of existing I2C buses and interruption foot to realize to external alarm low and high level
It the monitoring of signal and reports.
Above-mentioned alarm device, alarm module can be power fail warning, gate inhibition's alarm, location alarm etc..
The utility model has the following beneficial effects: the utility model using SFP mouthfuls of alarm device, do not need to communicate
Equipment reserves alarm signal interface, and by the way that External Alarm Module is arranged, multiplexed optical cause for gossip shows the transmission of external alarm signal.It is external
Alarm signal is converted into realizing with the low and high level of intercom set altogether to signal by lightning protection component and isolating chip
Lightning protection requirement is realized in filtration treatment protection, protects equipment internal circuit.Turned using the I2C bus and interruption foot of optical port by I2C
Extended chip is realized to the monitoring of external alarm low and high level signal and is reported.
Detailed description of the invention
Fig. 1 is that the utility model embodiment utilizes SFP mouthfuls of alarm device schematic diagram.
Fig. 2 is that the utility model embodiment with lightning protection component utilizes SFP mouthfuls of alarm device schematic diagram.
