4 TECHNOLOGY DISRUPTIONS
SET TO CHANGE CABLING AND
CONNECTIVITY
BY RON TELLAS
Disruptive technology alters the way we operate, driving us to
improve processes, operations and systems.
We're always watching for changes that will impact the industry and
bring new possibilities to the way our networks and cabling and
connectivity infrastructure are designed and deployed.
We rounded up a short list of four technology disruptions that Belden
is monitoring closely and think you should be, too.
1. SINGLE-PAIR ETHERNET
An Ethernet protocol - known as single-pair Ethernet - has been
designed to operate over a single pair of UTP/STP cable. Because it
uses only two conductors, the cable is lightweight, cost effective and
easy to install.
Although wireless devices can support some of the same
applications, it's important to remember that control and sensor
devices require power, too. With hundreds or thousands of devices and
sensors being deployed in a single facility alone, smaller is sometimes
better when managing and routing cables. This makes single-pair
Ethernet ideal for small IoT devices and sensors.
SINGLE-PAIR ETHERNET IS EXPECTED TO IMPACT FOUR AREAS:
* Enterprise IoT - single-pair Ethernet may support the connection of
more low-data devices as the industry moves toward smart buildings.
* On-board automotive sensors - connected smart cars require data
transmission to park automatically, warn of lane departures and
support smartphone apps. Single-pair Ethernet can connect a car's
networking system to on-board microcontroller units to provide these

features.
* Industrial automation - sensors and actuators similar to those in
automotive applications are used in industrial environments as well.
These devices don't require high data rates but need to connect to
the network to detect and report on things like environmental
conditions, which can be supported by single-pair Ethernet.
* Up to 20W Power over Direct Line (PoDL) - single-pair Ethernet
supports PoDL, which simplifies wiring by eliminating a separate
power cable. Single-pair Ethernet makes power supply with data
transmission possible.
WHAT THIS MEANS FOR YOUR CABLE INFRASTRUCTURE
Single-pair Ethernet offers a way to bring all your controls, sensors
and low-data devices onto an Ethernet network, as well as deliver
power.
2. Wi-Fi
Wi-Fi is a critical component in today's digital infrastructure; it offers
untethered device connectivity and supports IoT and smart buildings.
Once connected to Wi-Fi, devices can access the internet and
communicate with other devices on the same network.
Wi-Fi standards are developed by IEEE and designated by the
number " 802.11 " followed by letters that represent the technology's
generation and maximum speed and range. The Wi-Fi Alliance has
taken these standards and marketed them as " Wi-Fi " followed by
numbers and letters.
