For large systems that go far beyond what copper wires can reach, fibre-optic converters can used to work in both conventional point-to-point and advanced daisy-chain / redundant-ring configurations, giving your data network a boost in distance, ranging from 3 miles to hundreds of miles, and additional flexibility, reliability, and expandability.
The use of a Serial-TCP program is another ideal solution for merging serial communication protocols with modern TCP/IP communication, yielding benefits such as widely available infrastructures and greater distance, reliability, and speed. Point to Point Used mostly for one-to-one unbalanced signal (RS-232, TTL, and USB, etc.) extension, it can also be used for one-to-one optical fiber extension.
