SFP Gigabit Optical Fiber/TP interface
SICOM3024SM offers four pairs of redundant 1000Base-LX full duplex single mode
or multi-mode optical fiber interface (LC connector), or 1000Base-TX RJ45 interface
（
RJ45 connector
）
Port numbers are G1,G2, G3and G4. Optical fiber interface should
be used in pairs (TX and RX are a pair), TX interface is the transmitting end connected
to the receiving end RX of the optical fiber interface of another remote switch; RX is
the receiving end connected to the transmitting end TX of the same optical fiber
interface of the same remote switch. Four pairs of redundant 1000Base-LX optical fiber
interface can be used to form an optical fiber redundant ring network. In the event of
the system fault, the recovery time of the redundant ring network is less than 50ms,
effectively increasing the reliability of network operation.
