system is designed “to meet the
rising performance needs of mobile
network equipment and at the same
time reducing its size supporting
the ongoing space reduction
requirements”.
In June 2013 the new connector
system was submitted to the DKE1)
for standardisation with IEC2) to
follow in September 2013. The
ﬁnalisation of the standardisation
is expected in 2014. At the same
time the system will be available
with high quantities for the mobile
communication industry.
Belden has launched the OBR40
optical bypass relay from its
Hirschmann brand. Suitable for
use in harsh environments, the
relays increase the availability
of ﬁbre-optic Ethernet networks
by ensuring that they remain
operational despite power failures at
one or more switches. These relays
are designed for both ring and
bus topologies. Product Manager
Rolf-Dieter Sommer said: “Our
new OBR40 optical bypass relays
add a new level of reliability for
Ethernet networks. Even multiple
malfunctions do not impact the
network’s overall productivity.”
The bypass relay is available with
ports that support three different
ﬁbre types (multi-mode 62.5/125 µm,
multi-mode 50/125 µm, single-mode
9/125 µm). The switching threshold
is adjustable via a DIL switch over
a range of 1V to 32V. In addition,
a switch-on delay (adjustable for
intervals of up to 75s) allows the
switch’s boot process to complete
so that no data packets are lost
or delayed when a switch comes
back on line. The bypass relay also
features an IP30 protection rating,
an operating temperature range of
-40°C to +70°C, and a redundant
24 VDC power supply. The 115
x 61 x 113 mm metal housing is
DIN-rail mountable. LEDs on the

front panel indicate the status of
the device and network.
When a switch fails, an internal
switchover mechanism in the
relay enables data communication
to continue seamlessly between
neighbouring switches. The bypass
relay connects to a switch’s ﬁbreoptic uplink ports via two duplex
inputs/outputs. The mechanism is
designed to operate even when the
bypass relay loses power.
The bypass relay also supports atwill activation of the bypass function
for maintenance or selective
shutdown of parts of the network.
For example, when the wind gets
too strong in a wind park, or when
maintenance work is needed, one
or more turbines can be easily taken
out of the network without affecting
the connections of the remainder.
Lemo demonstrated four new
products at BVE 2013 further
building on the package of products
to support HD camera link systems.
A new lightweight Furukawa
6.8mm diameter HD hybrid ﬁbre
cable is available, manufactured
to SMPTE format including steel
central strength member with
reduced power conductors, to
provide a tough but light camera
cable offering weight savings of
approximately 45% compared
to standard SMPTE ﬁbre camera
cables. Maximum operating
distance is up to 1km depending
on camera system.
The latest Redel T7 connector
has been developed to meet
the increasing demands of HD
triax camera applications with
signiﬁcantly improved performance.
Fully compatible and intermateable
with the 1051 Series connector
commonly used for triax cameras
in Europe, the T7 connector has
the additional advantages of better
VSWR characteristics and a more
secure latching mechanism.

Available with either solder
or crimp contacts and with a
wide range of options to handle
the majority of triax cable sizes,
the Redel T7 connector is fully
sealed to IP68 to cope with all
weather conditions.
Lemo also offer a high
performance HD Triax 11 cable
specially manufactured to LEMO
specifications to match the
excellent transmission properties of
the LEMO range of precision triaxial
connectors including the new Redel
T7 for HD camera applications,
with low attenuation and high
level EMC screening properties.
Competitively priced against other
HD Triax cable, it is ideal for both
indoor and outdoor use, giving HD
transmission distances up to 30%
longer than standard triax cable,
says the company.
OMC now offers a ﬁbre optic link
service speciﬁcally tailored to meet
the demanding requirements of the
high voltage market. HV applications
such as power distribution
networks and power supplies
often require optical isolation
because of the voltages present,
however, achieving consistency of
performance has proven a challenge
for many providers.
Says William Heath, OMC’s
Commercial Director: “Most
manufacturers of optical fibre
cables don’t touch the transmitter/
receiver part of the link–similarly,
few Tx/Rx providers produce ﬁbre
cable assemblies. In our experience,
most customers don’t want to get
involved in either area; they simply
have an electrical signal at point
A and want to procure a link that
will convert it to an optical signal,
transmit it, and convert it back
to an electrical signal at point B

safely, reliably and consistently
from link to link. The problem is
particularly apparent in high voltage
applications where tolerances
can be very tight, and a lack of
consistency between transmitter,
receiver and cable characteristics
means that customers often
have to go through a lengthy and
costly selection process to yield
sufﬁcient complete links to satisfy
a production demand.
“We specialise in the manufacture
of both Tx/Rx devices as well as
the ﬁbre optic cable assemblies
to link between them. By tailoring
one of our existing processes we
are now able to supply production
quantities of fully-characterised
ﬁbre optic links with 100% link
consistency to leading producers
of HV equipment used in mass
transit, medical, power generation
and distribution, radar and x-ray
applications.”
Toner Cable now offers Aurora
Networks Fibre Optic Products.
Aurora Networks Products can
solve consumers demands for
new, bandwidth-intensive services.
Keeping pace requires headend and
hub equipment that is scalable,
flexible, easy to manage and
capable of accommodating new
services and technologies. Expand
your services, consolidate, upgrade
to ﬁbre deep or evolve to all-ﬁbre
with Aurora, says the company.
Adding Aurora to Toner’s product
line allows Toner Cable Equipment
to offer end to end solutions
from the satellite dish, through
digital headends, to ﬁbre to the
home. It also allows Toner Cable
Equipment Inc. to offer affordable
FTTX to gated communities and
Government facilities.

OMC specialises in the manufacture of both Tx/Rx devices as well as the ﬁbre
optic cable assemblies to link between them
