Bypass function
According to the specification of SFP optical module, the
usage of fiber port Bypass is as follows:
When SFP optical module is single-mode double-fiber, 1 set
of Bypass function is supported. Connection method is
shown below.
When SFP optical module is sing-mode single-fiber, 2 sets
of Bypass function are supported. The solid line and dotted
line each presents 1 set of Bypass connection method as
shown below:
When the switch is normally powered on and operating, it can
communicate with other devices normally. When it
’s powered
off, fiber port A and B can connect to each other without
interfering other devices
’ normal communication.
