The American Fibertek 48 Series transmits and receives (2) copper 10/100/1000 BaseT Ethernet signals at the RJ45 ports and (1) optical 1000 Base-X over 1 or 2 multimode fibers. The system is comprised of two units forming a point-to-point communications link.
The system is designed to be completely transparent with auto negotiation features which automatically configures the unit for the correct speed (10/100/1000 BaseT). Auto MDI/MDIX operation eliminates the potential need for crossover cables. Diagnostic indicators provide a quick visual indication of system status.
Equipment may be ordered as stand alone modules or rack cards that are mounted in the American Fibertek Card Cage: SR-20/2
