POWER OVER ETHERNET |
of IEEE 802.3bt’s release. The Ethernet
Alliance has a history of successful
interoperability testing with different
generations of PoE. The Gen2 EA Certified
PoE program will include a new test plan
and set of logos supporting IEEE 802.3btbased
098 Intertraffic World | Annual Showcase 2020
products as another demonstration
of the Ethernet Alliance’s commitment to
continually improve Ethernet user experience,
by minimizing interoperability issues and
market confusion.
Indeed, in December 2018, the IEEE
Standards Association honored the Ethernet
Alliance for its PoE certification program with
its IEEE SA Conformity Assessment Award,
celebrating major contributions to the
development and promotion of products
conforming to IEEE standards.
Users can easily identify standardsbased
PD and PSE products that will
work together, via intuitive, internationally
recognized EA certified logos or the Ethernet
Alliance’s online registry listing of certified
products. Having the Ethernet Alliance
symbol indicates that a product both has
undergone rigorous testing with many types
of PoE products in many configurations and
has been validated as conforming with the
industry-agreed-upon Ethernet Alliance
Certification Test Plan for interoperability.
The benefits of the Ethernet Alliance
certification program are far-reaching, and
include lower-risk deployment for suppliers
and industry alike, plus fewer support issues
and associated costs, as well as greater user
confidence in the interoperability, reliability
and safety of IEEE 802.3bt products in
networked environments.
In addition, the Ethernet Alliance’s online
registry listing certified products provides a
trustworthy resource for potential partners as
business relationships mature in the rapidly
expanding PoE marketplace.
The future for ITS
The base of PoE applications is growing with
innovation because of the increased power
standardized by IEEE 802.3bt. Dell’Oro Group
has forecasted 850 million PoE switch ports
to be shipped over the next five years. ITS is
one application space likely to see intensified
PoE deployment.
The new Gen2 Ethernet Alliance Certified
PoE program for IEEE 802.3bt will help pave
the way, by offering a trustworthy benchmark
for manufacturers and integrators in the ITS
space to point to in separating themselves
from the competition, as well as for federal,
state and local government agencies to
reference in bidding processes.
The Ethernet Alliance has a significant
number of current members involved in
ITS and welcomes all ITS equipment
manufacturers, integrators and designers
to get involved in its PoE certification
program and other activities.
Interoperable and compatible Ethernet
systems are already imperative to connect
and coordinate ITS from sector to sector,
city to city and state to state, and ongoing
collaborative efforts between the ITS
community and the developers of Ethernet
technology will help to eliminate the road
blocks to PoE deployment and bring ITS to
higher levels. ■
The IEEE 802.3 Ethernet Working Group
continues to deliver on its commitment to
ongoing standard improvements that deliver realworld
operational scenarios and meet challenges
faced by data network operators worldwide
