In accordance with an embodiment, an electrical cable can be configured to electrically connect to contact pads that are carried by a substrate. The electrical cable can include at least one, such as a pair, of electrical signal conductors and at least one, for instance a pair, of electrically conductive drain wires. A drain wire in the electrical cable can define a first surface that is configured to face the signal conductors and a second surface that is opposite the first surface. The drain wire can define a width that is greater than 0.12 mm as measured from the first surface to the second surface along a straight line. At least one auxiliary wire can be attached to at least one drain wire. The auxiliary wire can be configured to attach to the substrate.

An electrical heater and method includes heating member, a cable, and a connector. A resistance heating element is within a sheath of the heating member. A proximal end of the sheath is inserted into a slot of a first fitting and welded to the first fitting with first and second leads extending into the first fitting. The second fitting is threadably engaged with the first fitting. The second fitting defines a central bore disposed about the axis. An end of a power cable extends into the second central bore. A first wire is coupled to the first lead. A second wire is coupled to the second lead.

A crimp assembly for electrically contacting a conductive component of an electrical cable includes an anvil bushing and a compression sleeve. The anvil bushing has a retention shoulder extending circumferentially on an outer peripheral surface of the anvil bushing and supporting a section of the conductive component. The compression sleeve has an inner diameter larger than an outer diameter of the retention shoulder.

A modular hardware platform utilizes a combination of different types of units that are pluggable into cassette endpoints. The present disclosure enables the construction of an extremely large system, e.g., 500 Tb/s+, as well as small, standalone systems using the same hardware units. This provides flexibility to build different systems with different slot pitches. The hardware platform includes various numbers of stackable units that mate with a cost-effective, hybrid Printed Circuit Board (PCB)/Twinax backplane, that is orthogonally oriented relative to the stackable units. In an embodiment, the hardware platform supports a range of 14.4 Tb/s-800 Tb/s+ in one or more 19″ racks, providing full features Layer 3 to Layer 0 support, i.e., protocol support for both a transit core router and full feature edge router including Layer 2/Layer 3 Virtual Private Networks (VPNs), Dense Wave Division Multiplexed (DWDM) optics, and the like.
