The disclosure relates generally to an information handling system, and in particular, a cabling system for the information handling system.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes, thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Cables have become an integral part of information handling systems, include servers. Within a rack, across multiple racks, and across multiple servers (within a rack), communication is accomplished through cables. The cables can further connect one or more PCBs. Cables provide a lower loss mode for signal propagation compared to PCBs.
Innovative aspects of the subject matter described in this specification may be embodied in a cabling system, including a preform, including a divider; a cable, including: a first conductor; a first dielectric material surrounding the first conductor; a second conductor; and a second dielectric material surrounding the second conductor; wherein the first dielectric material is coupled to the second dielectric material, wherein the cable is at least partially coupled to the preform such that the divider is positioned between the first dielectric material and the second dielectric material.
Other embodiments of these aspects include corresponding systems and apparatus.
These and other embodiments may each optionally include one or more of the following features. For instance, the preform is cylindrical. The divider is positioned on an outer surface of the preform. The divider includes a first member extending at an angle from the outer surface of the preform; and a second member extending at the angle from the outer surface of the preform, wherein the first member is coupled to the second member at a ridge. The divider defines a distance between the first conductor and the second conductor. The angle defines the distance between the first conductor and the second conductor. The cable further includes: a first conductive material coupled to a portion of a first outer surface of the first dielectric material; and a second conductive material coupled to a portion of a second outer surface of the second dielectric material. The second conductive material is coupled to the portion of the second outer surface of the second dielectric material opposite to the portion of the first outer surface of the first dielectric material that the first conductive material is coupled to. The first conductive material and the second conductive material are conductive foil. The first conductive material and the second conductive material are conductive paint.
The details of one or more embodiments of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other potential features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.
This disclosure discusses a cabling system of an information handling system. In short, a cable can be bent such that the dielectric material of the cable is compressed. To compensate for an impedance drop of the cable when the cable is compressed, the cable is coupled to a preform such that a divider of the preform is positioned between dielectric materials of the cable to increase the distance between conductors of the cable. When the distance between the conductors is increased, the impedance of the cable is increased, compensating for the drop in impedance when the cable is compressed, described further herein.
Specifically, this disclosure discusses a cabling system, including a preform, including a divider; a cable, including: a first conductor; a first dielectric material surrounding the first conductor; a second conductor; and a second dielectric material surrounding the second conductor; wherein the first dielectric material is coupled to the second dielectric material, wherein the cable is at partially coupled to the preform such that the divider is positioned between the first dielectric material and the second dielectric material.
In the following description, details are set forth by way of example to facilitate discussion of the disclosed subject matter. It should be apparent to a person of ordinary skill in the field, however, that the disclosed embodiments are exemplary and not exhaustive of all possible embodiments.

Turning to
The preform 306 can include a divider 320.
In short, the preform 306 can facilitate routing of the cable 304 within the information handling system 202 (e.g., within a chassis of the information handling system 202). The cable 304 can be routed utilizing the preform 306. However, during routing of the cable 304 within the information handling system 202, the cable 304 can be bent (and further coupled to the preform 306) such that the dielectric materials 310 are compressed (“squeezed”). When the dielectric materials 310 are compressed, an impedance drop of the cable 304 occurs. To compensate for such an impedance drop of the cable 304 when the cable 304 is compressed, the cable 304 is coupled to the preform 306 such that the divider 320 is positioned between the dielectric materials 310. Positioning the divider 320 of the preform 306 between the dielectric materials 210 increases the distance between the conductors 308. When the distance between the conductors 308 is increased, the impedance of the cable 304 is increased, compensating for the drop in impedance when the cable 304 is compressed.
To that end, when the cable 304 is in a first state, as shown in
Moreover, when the cable 304 is in the first state, an outer surface 424 of the second dielectric material 310b is spaced-apart from an outer surface 426 of the second conductor 308b the first distance D1. The first distance DI is substantially constant between the outer surface 424 of the second dielectric material 310b and the outer surface 426 of the second conductor 308b around the second conductor 308b when the cable 304 is in the first state. That is, the dielectric materials 310 are in contact with each other when the cable 304 is in the first state.
Moreover, when the cable 304 is in the first state, the outer surface 416 of the first conductor 308a is spaced-apart from the outer surface 426 of the second conductor 308b a second distance D2.
To that end, when the cable 304 is in the first state, the cable 304 can be associated with a first impedance. The first impedance of the cable 304 can be based on the first distance DI and the second distance D2. That is, the first impedance of the cable 304 can be based on the distances between the conductors 308 and the respective outer surfaces of the dielectric materials 310, and a distance between the conductors 308 when the cable 304 is in the first state.
In some examples, a first conductive material 450a is coupled to the first dielectric material 310a. The first conductive material 450a can be coupled to the outer surface 414 of the first dielectric material 310a (away from the divider 320, shown in
The first dielectric material 310a and the second dielectric material 310b that do not include the conductive material 450a, 450b, respectively, are exposed between the conductors 308 such that there is electromagnetic (EM) coupling between the conductors 308.
Further, the areas where the dielectric materials 310a, 310b are located at the outer surface 414 of the first dielectric material 310a and the outer surface 424 of the second dielectric material 310b, respectively, are the areas where return currents of the cable 304 are most concentrated (compared to other areas of the cable 304).
To that end, the first dielectric material 310a is coupled to the second dielectric material 310b. Specifically, at least a portion of the first dielectric material 310a is coupled to at least a portion of the second dielectric material 310b. For example, along a length of the cable 304, at least a portion of the first dielectric material 310a is coupled to at least a portion of the second dielectric material 310b. For example, along a length of the cable 304, at least a portion of the first dielectric material 310a is coupled to at least a portion of the second dielectric material 310b via a webbing that connects the first dielectric material 310a to the second dielectric material 310b.
The preform 306 includes the divider 320. The divider 320 can include a first member 502a and a second member 502b (collectively referred to as members 502). The members 502 can extend from a surface 504 of the preform 306. In some examples, when the preform 306 is cylindrical, the divider 320 can extend around a circumference of the preform 306. In some examples, the divider 320 extends around a portion of the circumference of the preform 306.
In some examples, when the preform 306 is cylindrical, the preform 306 has a radius. To that end, a bending radius of the cable 304, when coupled to the preform 306, is dependent on the radius of the preform 306 (at the preform 306). The radius of the preform 306 can have a magnitude to ensure a minimum bending radius of the cable 304.
Referring to
Specifically, the cable 304 can be bent in the second state, and coupled to the preform 306. When the cable 304 is bent to place the cable 304 in the second state and coupled to the preform 306, the divider 320 can define the separation between the first conductor 308a and the second conductor 308b as the third distance D3.
When the cable 304 is in the second state, the outer surface 414 of the first dielectric material 310a is spaced-apart from the outer surface 416 of the first conductor 308a a fourth distance D4 at a first location 552 and a second location 554. The first location 552 is opposite to the second location 554. The fourth distance D4 is less than the first distance DI, shown in
Moreover, when the cable 304 is in the second state, the outer surface 424 of the second dielectric material 310b is spaced-apart from the outer surface 426 of the second conductor 308b the fourth distance D4 at a first location 572 and a second location 574. The first location 572 is opposite to the second location 574.
Moreover, when the cable 206 is in the second state (bent) and coupled to the preform 306 such that the divider 320 is positioned between the first dielectric material 310a and the second dielectric material 310b, the outer surface 416 of the first conductor 308a is spaced-apart from the outer surface 426 of the second conductor 308b the third distance D3. The third distance D3 is greater than the second distance D2, shown in
Specifically, the cable 304 can be bent (and further coupled to the preform 306) such that the first dielectric material 310a at the first location 552 and the second location 554 and the second dielectric material 310b at the first location 572 and the second location 574 is compressed. To compensate for an impedance drop of the cable 304 when the cable 304 is compressed, the cable 304 is coupled to the preform 306 such that the divider 320 is positioned between the first dielectric material 310a and the second dielectric material 310b to increase the distance between the conductors 308. That is, the divider 320 increases the distance between the conductors 308 such that the distance between the outer surface 416 of the first conductor 308a and the outer surface 426 of the second conductor 308b is increased from the second distance D2 (shown in
In some examples, the divider 320 defines the distance (the third distance D3) between the conductors 308. Specifically, the angle 602 that the members 502 extend from the outer surface 504 of the preform 306 can define the distance between the conductors 308. That is, a shallower angle 602 that the members 502 extend from the outer surface 504 of the preform 306 can further increase the distance between the conductors 308-a larger increase in distance between the conductors 308. A steeper angle 602 that the members 502 extend from the outer surface 504 of the preform 306 can increase the distance between the conductors 308 less than the increase between the conductors 308 when a shallower angle is used. In other words, the divider 320 increases the distance between the conductors 308, with a shallower angle 602 that the members 502 extend from the outer surface 504 of the preform 306 increasing the distance between the conductors 308 greater than a steeper angle 602 that the members 502 extend from the outer surface 504 of the preform 306.
In some examples, the angle 602 that the members 502 extend from the outer surface 504 of the preform 306 establishes the distance between the conductors 306 at the bending radius of the cable 304 (when coupled to the preform 306).
