FC-0 technology options

The following is taken from the FC-PH specification version 4.1.

FC-0 provides for a large variety of technology options. Tables 2 and 3 list the primary signal interface types, which are optical fibre and electrical cable. For each option the nomenclature is listed along with a reference to the clause within this standard containing detailed information.

In tables 4 and 5 the technology options are listed by the communications media types, both optical fibre and electrical cable. Each signal type has an associated primary media type. However, in some cases there is a listing for an alternate cable plant which may be used with degraded performance. These alternate cable plants are indicated by an asterisk in table 4. For more information on alternate cable plants see Annex C and Annex F.

The nomenclature for the technology options are illustrated in the following figure:
