Application diagram of fiber bypass switch
What is bypass switch?
Bypass unit or module is usually used to protect the network system(bypassing the device it connects) when power is suddenly off.
In a linear network system(like below diagram), the transmission is fine if the data/SFP/power is normal.
What if any power supply is off (like power surge, striking, man-made damage...)
The whole network system will fail.
Another situation is, power overhaul/maintenance is required for switch 2(the middle one) area, lets say for 12 hours, the whole system got to stop.
With a bypass module/switch, it is like putting in a protection mechanism in the whole system.
A bypass switch helps protect the whole system if one or many switches fail at the same time.
