3.14.3 Monitor by SFP 
Optical fiber is commonly used for long distance data transmission. However, when link issues occur, 
it is very costly to trouble shoot the fiber cable and fiber transceiver at remote sites. To solve this 
problem, Weidmüller industrial Ethernet switches provide digital diagnostic and monitoring functions 
on Weidmüller SFP optical fiber links and allow users to measure optical parameters and its 
performance from center site. This function can greatly facilitate the trouble shooting process for 
optical fiber links and reduce costs for onsite debug.
