TRANSMISSION LINE INTERFACE
Operating distance is dependent upon optical fiber core diameter and the cable's optical attenuation. The table
below indicates three cables that may be used at any data rate. These cables are available in connectorized assemblies
to meet the exact configuration of your application.
S.I.Tech offers complete links including fiber optic cable, connectors, cable assemblies, and Bit-Drivers®.
