CABLES AND CONNECTORS

Digital audio cables and connectors

There are two common types of digital audio cable:
Type
Digital coaxial cable
Optical digital cable
SMART products with digital audio connectors
The following SMART products have digital audio connectors:
Product type
Displays
Projectors
NOTE
Refer to other SMART products' specifications to see if they support this type of connection.

Minimum requirements and guidelines

There are no minimum requirements or additional guidelines for selecting digital audio cables.
However, because digital optical cables are less durable, a best practice is to use shorter cables to
reduce the risk of damage.

Details
A digital coaxial audio cable has RCA connectors at both ends. The RCA
connectors are plugged into the orange digital coaxial receptacles on
both the source and receiving device. A digital coaxial audio cable's
signal is subject to weakening when it passes over long distances.
Optical digital cables use plastic filaments, similar to fiber optics, that
use light to transmit the signal. Although audio signals delivered by light
don't weaken as they do with copper-wired cables, optical digital
cables can be damaged by excessive twisting or curling. This risk
increases when these cables run over longer distances. If possible, use
a different type of connection if the cable run must be longer than 4'–6'
(1.2–1.8 m).
The connector on an optical digital cable looks like a small square plug.
This connector can come in a standard or mini size.
