CL-RS232, RS-232 to Fibre Converter

CL-RS232 media converter is a solid solution for applications that require a reliable link of remote terminals to host computers. The unit offers cost-efficiency for extending distances ranging from 2km (multimode), 20km (singlemode), and 110km (long haul singlemode fibre, one-strand fibreoptic solution). Together with its simple-to-setup and install characteristics, the converter makes it easy to combine the advantages of fibre technology within a RS-232 copper-based network. By facilitating the integration of the existing copper cabling with newer fibreoptic cabling, the CL-RS232 represents a cost-effective solution for network administrators eager to keep costs down when upgrading. The converter is ideal for connecting data communication devices situated amongst manufacturing intensive environments where electromagnetic and radio frequency interference is a major concern. Data integrity is also assured due to the nature of fibreoptic cable making any comprise in transmission detectable.
