Checks and branches
Xtera Communications has launched a
subsea branching unit (BU) that builds on
technology already successfully deployed
in its repeater.
Branching units are used in submarine cable
systems to provide traffic and power routing
between the trunk and branch cables,
enabling complex and reconfigurable
network architecture for more flexible
capacity configurations. They also make
fault recovery more simple.
Following
customer
feedback
that
re-configuring the powering of a system
can be time consuming and difficult, Xtera
has used the supervisory system to allow
operators to switch the BU powering simply
by sending commands.
This avoids the need to disconnect or
change the polarity of power feed
equipment or arrange for synchronized
ramping to ensure the desired current flow
during re-configuration.
There is also circuitry to minimize the effects
of current surges, to allow hot-switching and
to hold the configuration during a power
loss.
“We have focused on making the BU robust
and easy to use,” said Stuart Barnes, senior
vice president and general manager,
Xtera Submarine Business, adding that the
technology “also makes it possible for a user
to check the BU operation via the network
management system.”
Fine wire braiding
The Wardwell RS 16 is designed for braiding
super fine wire from 0.02mm (52 awg). The
RS 16 has a 30 percent smaller footprint than
traditional lever arm machines, allowing for
a more efficient use of workspace.
The RS 16 braids super fine wire over cables,
mandrels and tubes for mini coaxial and
special cables, and for medical catheters.
This machine has all the standard features,
including payoff and take-up for DIN 355
reels, with the additional options of 1x1
braiding pattern; multiple payoff and
take-up options; an empty bobbin detector
with positioning system; and longitudinal
tape attachment.
Suiting high salt conditions
Beacon Fasteners and Components has
expanded its thread forming line with high
salt spray full trilobe thread forming screws.
