Checks and branches

Fine wire braiding

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. 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.” Following customer feedback

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.
