Differentiating Factors between PoE, PoE+, and PoE++ Switches

Differentiating Factors between PoE, PoE, and
PoE Switches

• PoE is gaining momentum owing to the simplicity
  and ency it assures and saves on external
  electric supplies for powering efficidevices.
  Like other technologies, POE is administered
  through several PoE devices, such as PoE
  switches. There are different versions of Power
  over Ethernet switches in use today PoE
  switches, PoE switches, and PoE switches.
  Would you like to know more about these switches?
  If that sounds yes, then this Presentation
  answers everything about these devices. So, stay
  tuned.

PoE

• A PoE switch has in-built Power over Ethernet
  functionality. These types of switches supply
  power to network devices using Ethernet cables,
  like Cat6 cable. If there are distributed
  switches in your network, it is possible to get
  PoE pass-through switches. These switches can
  also pass power to end devices such as phones,
  cameras, and so on. Most of the 802.3af switches
  can deliver 15.4 watts over an Ethernet cable
  with a voltage ranging from 44v to 57v.

PoE

• As the name suggests, it is an advanced version
  of PoE technology developed and published in 2009
  by the Institute of Electrical and Electronics
  Engineers (IEEE 802.3at standard). In many cases,
  power devices within the network require more PoE
  wattage up to 12.95, and, PoE is the best
  solution that supports a higher power consumption
  requirement. Like a PoE network switch, PoE
  supplies power over two pairs. But, it has an
  additional power class that can deliver power
  watts up to 25.5 with a voltage range varying
  from 42.5v to 57v. A PoE network switch can
  supply maximum power of 30W with a voltage range
  from 50v to 77v.

PoE

• PoE network switch is the next generation of
  PoE technology. It is designed to provide power
  to broader device applications. It is classified
  into two different types PoE type 3 and PoE
  type 4. Type 3 powered switches can hit 51 watts
  with a voltage range from 42.5v to 57v. Type 4
  switches enable four twisted pairs in a copper
  cable to deliver power up to 71 watts. Being an
  upgraded version of the PoE network switch and
  PoE switch, PoE can hit 60 watts on each port
  under PoE type 3 and up to 100 watts under the
  PoE type 4.

PoE vs PoE vs PoE - Know the Real Difference

• One of the major differences between PoE, PoE,
  and PoE switches is the IEEE standards. A PoE
  switch is designed as per 802.3af, PoE as per
  802.3at, and PoE as per 802.3bt.
• Next, Ethernet cabling is an important
  consideration when differentiating these
  switches. PoE switch use two pair twisted cables,
  and the same goes for the PoE network switch. On
  the other hand, PoE uses four pairs of twisted
  cables. 
• Differences among these switches lie in the
  maximum power supply delivered by each port and
  their working mode, which reflect on their
  applications. PoE switches are designed to
  support network devices that require a power
  supply of up to 15.4watts. The list includes
  sensors, meters, wireless access points,
  surveillance systems, and many more. PoE
  switches support devices such as video IP phones,
  wireless access points with multiple antennas,
  and complex surveillance cameras. PoE switches
  can support devices that need higher power
  wattage such as video conferencing system
  components and building management devices,
  laptops, televisions, and so on.

After understanding PoE switches and their
increasing use in several industrial
applications, it is essential to source them from
the authorized and certified manufacturers and
suppliers. VERSITRON is one of the leading and
trustworthy manufacturers and providers
of industrial PoE switches. Over the years, the
company has been offering PoE switches in
different configurations. These switches support
Ethernet, Fast Ethernet, and Gigabit Ethernet
applications for secure and enhanced
communication links. The company also offers
several other network devices for fiber optic as
well as blended networks.
