The fiber modem is a low cost, compact, fiber converter designed to extend RS-232 transmissions up to 120Km without any repeaters. The transmissions run in fibers which provide for excellent data security as well as being immune to EMI/RFI, variations in ground potentials, and lightning strikes. With the selectable baud rate, the user can choose its own rate for the transmission. The fiber modem operates at the physical layer (OSI Layer 1) and is completely transparent to the RS-232 transmissions and protocols. The fiber modem may use an external power adapter. Utilizing an ST, SC fiber cable, the fiber modem operates in Full Duplex mode for bi-directional transmissions. The fiber modem RS-232 interface operates in DCE mode for direct connection to DTE devices such as PC DB9 port.
