Title: Differentiating Factors between PoE, PoE+, and PoE++ Switches
1Differentiating 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.
2PoE
- 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.
3PoE
- 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.
4PoE
- 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.

6PoE 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.
7After 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.
