1694F, a flexible version of Belden’s ever-popular 1694A, offers outstanding signal
transmission quality and reliability. Both 1694F and 1694A use the same connector type, eliminating
the need for additional tooling and connectors.

Belden Brilliance 1694F is an extremely flexible
version of Belden’s popular industry standard,
1694A. Like 1694A, this RG-6/U Type Low Loss
Serial Digital coaxial cable provides top quality
signal transmissions (both analog and digital).
It also offers the user the benefit of superior
cable life—whether it’s used indoors or out-ofdoors
(Black jacket only). And unlike other
manufacturers’ cables, 1694F provides the enduser
and the installer with some unique cost and
labor-saving benefits since it accommodates the
same connector as 1694A, and therefore the same
type of tool, throughout its installation—even at
the patch panel.

Exceptional Flexibility and Flex Life

Belden Brilliance 1694F’s flexibility makes this
CM-listed cable easy to route through building
walls and conduit in studio settings and other
fixed installations. But 1694F’s exceptional
physical and electrical characteristics really make
this cable ideal for use in patch bays, mobile
studio trucks, remote outdoor field locations,
and more. Today’s on-the-move broadcast crews
routinely subject the cables they use to repeated
pulling, flexing, bending and crushing situations.
Under these circumstances a conventional cable
might develop discontinuities that could lead to
degraded signal transmission—or the cable could
even break. But Belden 1694F offers outstanding
flexibility and long-life characteristics and an
abrasion-resistant PVC jacket—in conjunction
with superior electrical performance.
　

In addition, digital audio signals are increasingly
run through coax in accordance with Audio
Engineering Society standard AES-3id.
Belden 1694F is an excellent choice for AES-3id
applications where optimum flexibility and
flex life are required.
　

Low Return Loss = High Performance

Return Loss relates to the measurement of
the reflected signals that occur when there
are impedance discontinuities in the channel.
These discontinuities can be caused by the
connectors, transition devices, patch panels
or the cable itself—or they could be the result
of improper handling, poor installation
practices or repeated flexing of the cable.
　

To ensure best-in-class Return Loss performance,
each shipping spool of Belden 1694F SDI/HDTV
cable is 100% sweep tested to 4.5 GHz before
being boxed. Belden is the only cable manufacturer
that has extended its testing to 4.5 GHz—
the 3rd harmonic frequency of 1080p. This
should assure broadcasters and leading-edge
broadcast equipment manufacturers of high
performance and reliability as they begin to
migrate to the emerging SMPTE 424M 1080p
(progressive format)—where protocols and
equipment require twice the bandwidth of 1080i.
　

Best-In-Class Design and Construction

The robust performance and enhanced flexibility
of Belden 1694F is the result of its unique design
and construction.
　

Optimum flexibility starts with a 19 AWG bare
copper (compacted), stranded center conductor.
Advanced impedance stability and Return Loss
characteristics are achieved by the use of foam
polyethylene insulation and state-of-the-art
manufacturing processes.
　

The cable’s shielding consists of a double tinned
copper braid. This shielding construction provides
superior flex characteristics over foil/braid shield
designs, while offering 100 dB of shield isolation.
An abrasion-resistant matte PVC jacket adds
further protection and flexibility and is available
in seven colors.
