Fiber Networks
Note
: The maximum cable length for copper ports is 100 meters and 10km to 70km for fiber
ports depending on the SFP module you install (the example here uses ORing’s SFP 1G
modules which supports up to 20km). When data bypasses the inactive switch(s) to another
active switch, the distance between the two active switches must be within the maximum
length, otherwise transmission will fail.
4.5 MRP
4.5.1 Introduction
MRP (Media Redundancy Protocol) is an industry
standard
for high-availability
Ethernet networks. MRP allows Ethernet switches in ring configuration to recover from failure
rapidly to ensure seamless data transmission. A MRP ring (IEC 62439) can support up to 50
devices and will enable a back-up link in 80ms (adjustable to max. 200ms/500ms).
