Fiber Check
Optical fiber is commonly used for long distance data transmission. However, when link issues occur, it is very
costly to troubleshoot fiber cables and fiber transceivers at remote sites. To solve this problem, the Moxa
PRP/HSR RedBox provides digital diagnostics and monitoring functions on the Moxa SFP optical fiber links that
allow users to measure optical parameters and performance from the central site. This function makes it much
easier to troubleshoot optical fiber links, and virtually eliminates the cost of onsite debugging at remote sites.
