S.I.Tech 2351 Ethernet to fiber Bit-Driver® is board level fiber optic communication product fully tested for compatibility with leading 16-Bit ISA bus computers including IBM AT's and compatibles, Providing complete compatibility to the widest variety of PC platforms though a proven buffered slave architecture, Desktop Management Interface (DMI) equipped drivers provide board client PC manageability.

The use of this board in a computer requires that a companion fiber optic transceiver (see fig. 1) be located at the termination end to any Ethernet medium, AUI, coax or twisted pair.

TRANSMISSION LINE INTERFACE

Operating distance is dependent upon optical fiber core diameter and the cables' optical attenuation. The table below indicates cables that may be used at any data rate. S.I.Tech offers complete links including fiber optic cable, connectors, cable assemblies, and Bit-Driver®.
