                 	                    The fiber optic hub for star formation fiber network, RS-232/485/422 transparent transmission on fiber optic star network. Fully adaptive user agreement without changes. As a result of the fiber as a transmission medium, you can completely avoid the threat of harsh environments lightning, surges, electromagnetic interference and other communication devices while eliminating the investment surge lightning protection devices when the original use of copper, greatly improved data communication reliability, security and confidentiality.
