The VK250 is an extremely reliable high-speed low-cost point-to-point fiber optic clock and data modem. It is designed to link a remote terminal to the host computer via one or two single-mode optical fibers. Users may plug the VK250 modem into any standard selectable EIA-RS422/530 interfaces or special clock & data cable.
Using fiber optic CWDM technology the VK250 can transfer high-speed synchronous data up to 20 Mbps. It also provides a DCD signal when the receiver has received a data signal from the far end while the RTS and DTR control signals are internally loop backed for handshaking applications. Transmission distances can be used up to 50 Km with single mode fiber optic cable.
The VK250 is designed for any general-purpose application between data communication equipment. Typical applications include remote terminal to host computer connections, tail circuits to multiplexers, monitoring equipment to a central control system, and situations requiring extended distances. It may also use in harsh environments because fiber optic cable is virtually impossible to tap without detection.
Applications for the VK250 Series include campus fiber Traffic Control System, Metro Operation System, SCADA systems, Campus Networks and military applications.
