Fibre Optic Modem – LRW-102 PP
The LRW-102PP is a fibre optic modem designed for point-to-point fibre opticconnections between LONWORKS networks. The LRW-102PP offers an easy way to extend the distance between LonWorks® 78 kbit/s TP/FT network segments using a fibre optic link. The LRW-102PP is designed for harsh industrial usage as well as road or railway installations meeting industrial level EMC specifications and having a wide operating temperature range. The unit also has a re-timing function that eliminates the problem of jitter andhence ensures reliable communications in all situations.
