Jack Plate Types
There are three basic types of mounting plates for modular jacks: fixed plates, modular
plates, and modular assemblies. Don't be confused by the word “modular” here, as we
are referring to the fact that some of these devices snap together with different options.
Fixed jack plates are the traditional type of plate. These plates are made of
molded plastic and include the opening for the modular connector as well as a
mounting for the connector and termination components. The most common fixed
jack plates have one or two connector positions and are often referred to as
simplex
or
duplex jacks
(respectively).
The plate opening and its related molded structures form an integral part of the
connector assembly. The connector cannot be separated from the plate and used
alone. This is the reason the jack plate is called
fixed
. The supports for the connec-
tor terminations are also usually molded into the plate. The most common type of
termination is a screw and washers that attach to a molded post on the back of the
plate. An example of a fixed jack plate is shown in Fig. 6.7.
With the advent of structured wiring and the tough requirements of Category
5, modular jack plates and their associated connectors have become much more
