This blog post is part of a series called “CommScope Definitions,” in which we will explain common terms in communications network infrastructure.
Today’s intelligent buildings have some of the latest
technology deployed inside, which is causing ICT designers to re-consider traditional
installation practices. For example, previously, the majority of network computing
devices were in offices or equipment rooms, with the horizontal cabling
terminating at an equipment outlet or panel – with devices connected via a
conventional patch lead. With the mass proliferation of IoT sensors/devices and
other advanced technologies, we are increasingly seeing devices placed at high
levels, such as in ceiling voids, which requires a more contemporary approach
to their management and connectivity.
new way to connect in modern buildings
help eliminate complexity and reduce security risks, we are increasingly seeing
devices such as surveillance cameras connect directly onto the horizontal
cabling using an RJ45 modular plug. This
is known as the Modular Plug Terminated Link (MPTL) method, and it simplifies
connectivity into such devices by taking out the need for a separate patch
cord. The MPTL enables the cable to be plugged
directly into a device, so it can be connected to a network without installing
an additional outlet; which has many installation and user advantages. Notably, by eliminating the extra connection
points introduced by outlets and patch cords, network operators are seeing the
benefits of rapid device deployment, improved power performance and enhanced

Ensuring compliance and error-free operation
2018, the MPTL was approved under the TIA 568.2-D standard. However, to ensure
that link is installed and deployed correctly, the standards specify strict
limitations to its use and define a new and comprehensive testing criterion. In
addition, fitting RJ45 plugs directly to horizontal cabling in the field has
always been both difficult and time consuming, especially when higher frequency
and higher bandwidth cabling solutions (such as Category 6A) are deployed. This
intricate connectivity process has historically been carried out under factory
conditions, to ensure performance and quality of termination. Although some
manufacturers have produced an RJ45 plug for use and termination in the field,
CommScope does not endorse such an approach due to the complexity and margin
for error/failure; especially when at high level or in confined installation
environments. However, recognizing the need for a MPTL solution, Commscope
designed and developed the Ceiling Connector Assembly (CCA) to offer a
simplified connectivity process that ensured quality and offered customers both
security and flexibility.
of the CCA for a MPTL deployment
CCA uses a factory terminated plug and IDC connection point, which allows the
termination of the horizontal cable via a fast, tool-free, installation method.
In summary, the CCA helps ensure the performance and integrity of the link by
simplifying the termination even under difficult conditions. This not only
reduces the risk of installation issues or latent defects, but also eliminates
the need for any specialized testing.
