Pick up any cabling catalog, and you'll find a plethora of components
and associated buzzwords which you never dreamed of. For example patch
panel, wall plate, plenum, modular jacks, raceways, fiber optic pigtails
and patch cords are a few. What can all of them mean, and just how are
these elements utilized to create a structured cabling system?
Within this blog, we'll provide some info about the structured
cabling system so that you won't feel so confused the next time you pick
up a cabling catalog or use professional cabling installers. Today, we
mainly explain the cable components relevant information. If you wish to
find out about components, pls visit FiberStore Tutorial, you can
expect some detail information about the fiber optic components.
We'll describe the components associated with transmitting data from
the workshop for the telecommunications room or enclosure. These major
cable components are horizontal cable, backbone cable, and patch cords
utilized in cross-connections and then for connecting to network
devices.
Horizontal and Backbone Cables
The terms horizontal cable and backbone (sometimes called vertical or
riser) cable have absolutely nothing related to the cable's physical
orientation toward the horizon. Horizontal cables run between a
cross-connect panel in a telecommunications room plus a
telecommunications outlet located nearby the work space. Backbone cables
run between telecommunications rooms, and enclosures,as well as the
main cross-connect point of a building (usually found in the equipment
room). The image illustrates the standard components found in a
structured cabling environment, like the horizontal cable, backbone
cable, telecommunication outlets, and patch cords.
Fiber Patchcord
Fiber patchcord
can be used in patch panels to offer the connection between
field-terminated horizontal cables and network connectivity devices (for
example switches and hubs) and connections between the
telecommunications outlets and network devices (for example computers,
printers, and other Ethernet-based devices). These are the section of
the network wiring it is possible to see. As the saying goes, a sequence
is only as strong as its weakest link. For their exposed position in
structured cable infrastructures, patch cords are nearly always the
weakest link.
Whereas horizontal UTP cables contain solid conductors, patch cords
are created with stranded conductors because they're more flexible. The
flexibleness lets them withstand the abuse of frequent flexing and
reconnecting. Even though you could make your own field-terminated patch
cords, we strongly recommend against it.
The manufacture of patch cords is quite exacting, and also under
controlled factory conditions it is sometimes complicated to accomplish
and guarantee consistent transmission performance. The very first
challenge lies within the modular plugs themselves. The parallel
alignment from the contact blades forms a capacitive plate, which gets
to be a supply of signal coupling or crosstalk. Further, the untwisting
and splitting with the pairs because of the termination process
increases the cable's susceptibility to crosstalk interference. In the
event that weren't enough, the mechanical crimping procedure that
secures the plug to the cable could potentially disturb the cable's
normal geometry by crushing the conductor pairs. This is one more supply
of crosstalk interference and a way to obtain attenuation.
Tip:Patch cords which were factory terminated and tested must
achieve consistent transmission performance. Initially, patch cords may
seem like a no-brainer, nevertheless they may actually function as the
vital aspect of accurately specify. When specifying patch cords, you may
even require that your patch cords be tested to ensure that they
satisfy the proper transmission-performance standards for their
category.To find out more about fiber optic patch cable types or need it the patch cable, pls contact this email: sales@fiberstore.com.
