In the event that the limits for the number of transceivers or total wire distance are exceeded, then one FTT physical
layer repeater (PLR) can be added to interconnect two segments and double the overall system capability. FTT-10A
Transceivers are used to make physical layer repeaters. See the FTT-10A Free Topology Transceiver User’s Guide for
more info on PLRs.
System Performance and Cable Selection
TP/FT-10 channels must meet the System Specifications and Transmission Specifications as outlined below. When
creating documentation and installation procedures for TP/FT-10 channels, be sure to include the TP/FT-10 system
specifications and, based upon the cable used, the appropriate transmission specification listed below. Incorporating
these specifications will ensure a smoother installation and provide a resource for the installer who must troubleshoot
the installation.
