Why Do You Need CAT 6A Cables for Power Over Ethernet?

Description:

Sometimes, if high power is running through a cable, it can cause performance issues by making the cable hot leading to high insertion loss. In such cases it’s best to use CAT 6A cables. This article explains why. To know more about product at – PowerPoint PPT presentation

Title: Why Do You Need CAT 6A Cables for Power Over Ethernet?

Why Do You Need CAT 6A Cables for Power Over
Ethernet? Whenever you want to supply
electricity to different types of networking,
computing devices and AV without an adapter,
Power Over Ethernet (PoE) technology works the
best. Also, it lessens the number of building
materials needed to connect and power a device
through a single cable which takes care of both
the services. As the powered devices of today
are no longer restricted to security cameras and
VoIP phones such devices utilize Power over
Ethernet connections. These devices also need
high power levels. A new Power Over Ethernet
(PoE) standard called - IEEE 802.3bt, supports up
to 100W of power per cable. Sometimes, if high
power is running through a cable, it can cause
performance issues by making the cable hot
leading to high insertion loss. In order to curb
this phenomenon from affecting productivity,
Ethernet cables like CAT5 cables and CAT6 cables
are used. But the best cables to use during such
times are CAT 6A cables. Heres why

  • They cause less power loss
  • If you use 24-gauge CAT5E cables, you might lose
    nearly one-fifth of the total power. Now this is
    a lot of power loss. Doing the math, you will
    notice that it will cost you around 7/year.
    Count this per year for every PoE device used
    across your facility including all
  • surveillance cameras and wireless access points.
    Hence, if you dont want high operation costs, go
    for 23 gauge CAT 6A cable which has the potential
    to maximize the power running through itself and
    boost the energy efficiency. It will ensure that
    the power which is transferred through the cable
    is utilized at its best by decreasing
  • the operation costs.
  • They have large gauge diameter
  • CAT 6A cables offer a large gauge diameter that
    lowers the resistance and controls power waste.
    This is because the tendency of temperature to
    increase is much low as compared to small gauge
    CAT 5E and Category 6 cables. Using 6A cables,
    you can get
  • larger bundle sizes, higher ambient temperatures
    and flexibility. Try to compare a 23-gauge
    cabling with a 24-gauge one and you will
  • see a huge difference in how the power is
    handled. Nearly 20 power through the cable gets
    lost in a 24-gauge CAT 5E cable which leads to
    inefficiency.

3. They can handle heat emitted from tightly
packed cables Usually if your cables are
compactly packed in pathways, the heat will
definitely increase as it cannot dissipate away
from the cable. Most of CAT6 A cables have an
insertion loss margin which is capable to handle
the heat generated from tightly packed cables
without affecting the performance of device.
However, this is not applicable to all types of
Category 6A cables. Although most of these
cables offer a 100 m solution, some of them also
might have an 85 m solution if temperature rise
is too much. So make sure that you go for a cable
that helps you maintain its full 100 m
performance.Now that you have known the
importance of CAT6A cables and its advantages for
Power Over Ethernet, you can make the right
choice!
