Bryant Unlimited Complete The Circuit
Bryant Unlimited started life in 1982 as Bryant Broadcast when Ross
Scott saw a gap in the market for the manufacture and supply of cable
assemblies for the Broadcast and Data Networking industries...

elling for a cable manufacturer
Ross Scott was often asked
whether they would supply cables
with connectors fitted and luckily
for him his then employer turned
down the concept.
Bryant was established and
one thing led naturally to another
as customers then wanted their
connectors mounted onto metal
panels and the panels mounted
into 19" racks. Thus began the
company that today is known as
Bryant Unlimited.
The change of name reflects that
as an ISO 9000 manufacturer with
in-house wiring workshops and
a fully equipped metalworking
facility Bryant is not just the System
Integrators friend when it comes to
the three Is of signal management
(Interconnection, Interface and
Installation) in the broadcast and
communication industries.
Bryant has grown consistently to
become an acknowledged service
leader across many other sectors
including fibre optic cables,
equipment for AV installations;
data networking and supplies to
medical, educational and military
markets worldwide.
Alongside
manufacturing,
Bryant's Website and distribution
hub offer 'best choice' solutions
for the technical install, sourced
from World leading manufacturers
or designed and built in-house to
solve the engineer's dilemma.
The initial vision of satisfying the
customers' needs has been taken
forward by the Reverend Ingrid L.
Scott and her team into constantly
evolving eco-friendly areas like
optical fibre camera cables
and power distribution units for
broadcast and IT racks.

Optical Fibre Camera Cables
Bryant Unlimited has evolved
to become the UK's leading
manufacturer of optical fibre
interconnects for audio and
high-definition video broadcast
plus network and high-end A/V
applications.
Bryant has invested heavily
in the equipment and expertise
necessary to assist installers
in using fibre to transport HD,
3Gb/s and Gigabit Ethernet over
fibre optic media. By monitoring
customer demand Bryant were
able to take the lead and transfer
their wiring skills from multipair
and coax/triax cabling to optical
fibre camera cabling. Bryant sell
SMPTE 311M, single-mode fibre
optic and copper hybrid camera
cable,
manufactured
using
Furukawa 2SM-9.2-37.5 ARIB
specification cable, terminated
with
Lemo
SMPTE
304M
connectors including sleeves,
dust caps and gaiters, for high
definition video camera to CCU
interconnect.
As well as being a franchised
LEMO SMPTE 311 camera
cable manufacturer, Bryant is an
approved Neutrik OpticalCON
assembler and repairer. This
'system' is based on a standard
optical LC-Duplex connection,
but helps to eliminate its inherent
weakness to produce a more
rugged connection. Bryant can not
only manufacture but also rebuild
most makes of SMPTE camera
cables in their Croydon, UK
premises; thus avoiding the costs
of sending imported cables back
to the USA or Asia for repair.
To
complete
the
circuit,
Bryant
also
sells
Broadata

Bryant Unlimited has in-house wiring workshops and a fully equipped metalworking facility.

Bryant's state-of-the-art intelligent eyePower mains distribution unit.

Communications, Inc. marketdriven
products
for
the
transmission of digital multimedia
(video, audio, and data) over fibre.
eyePower MDU Unleashed
Bryant
Unlimited
have
manufactured 'intelligent' Mains
Distribution Units since the 1990s
and the eyePower MDU is the very
latest design.
eyePower is a newly developed
platform again based purely upon
customer demand for functionality
hence
offering
the
highest
standard of monitoring and power
status reporting in mission critical
installations such as Broadcast
and IT, where loss of on-air time or
data is a killer.
This super stable, highest
resolution Power Monitoring MDU
for broadcast and IT racks has
control and monitoring deliberately
performed by separate microcontrollers.
An intelligent MDU available in
many configurations with 14 IEC
outlets; 20A powerCON single or
dual inlet auto-changeover from
main to back-up power in event
of power failure; comprehensive
control and monitoring of inlet and
outlet parameters over multidrop
serial or optional Ethernet interface
with PoE; 1-Wire sensors for
environmental monitoring - all in a
1U rack mount unit.
Like all Bryant Unlimited mains
units eyePower does not rely on
PCB tracks for power distribution;
all units are hand wired with
crimped cables and soldered
busbars.
eyePower Outlets are 10A rated

to the unit maximum of 20A.
Factory fit is 3.15A fuses which
suits most loads and provides
clear
discrimination
between
supply and outlet fusing.
Supply voltage is detected
after each fuse and after each
relay, using a circuit which
consumes 0.25W total for over 30
measurements.
Current
measurement
is
performed with high sensitivity
current transformers. Unlike cheap,
PCB mounted shunt resistors
there are no heating issues and
reliability is maintained by simply
passing the output cable through
the centre of the transformer rather
than routing via the PCB. Currents
from mA to 40A (Crest Factor 2)
can be monitored.
The PSU is high quality, a
linear supply with over-specified
components that runs much cooler
than a cheap switched mode unit
with limited life. Linear supplies are
more tolerant to supply harmonics
and voltage dips.
Bryant Unlimited
As a company Bryant are large
enough to offer the best in service
and product availability whilst
small enough to still pay attention
to detail at the design and
manufacturing level.
The only constant thing in system
install is change, but with Bryant
Unlimited as your partner, you will
be kept up-to-date with the latest
cable and connector technology,
designed to the highest standards
and performance requirements,
and delivered with the highest
levels of service.
