CYGNUS 412 Fast Ethernet to Fiber Media Converter

CYGNUS 412 Fast Ethernet Media Converter supports 10/100 Base-Tx to 100 Base-Fx media conversion. Bi-Di technology allows one fiber to be saved as compared to other Media Converters which use Duplex Fiber. Simultaneous 2-way communication between a pair of CYGNUS 412 units is using only one interconnecting fiber circuit between them
