A 60Pin 40AWG ultra-thin coaxial cable assembly solution for high-speed, miniaturized devices
With the continuous development of laptops, tablets, VR/AR, high-speed display equipment, and high-density electronic devices towards thinness and high speed, traditional cables are facing increasingly high requirements in terms of space occupation, signal integrity, and EMI control. In response to such applications, this solution focuses on the compatibility and replacement design of the I-PEX 82997-100B-01-D ultra-fine coaxial cable, using 40AWG Micro-Coaxial (ultra-fine coaxial) cables, with the wire position defined as 1--1, corresponding to the CABLINE®-CA II PLUS 60Pin high-speed connection scheme. According to I-PEX official data, this series of connectors adopts a 0.4mm contact spacing and a horizontal insertion structure, supporting the highest 32Gbps/lane PAM4 high-speed data transmission, and has structural characteristics such as full shielding and mechanical locking tabs.
For engineers, the value of the extremely thin 40AWG coaxial cable lies not only in its "slimness," but more importantly, in its ability to achieve high-density, high-speed signal wiring within limited device space; for purchasers, it is necessary to further pay attention to cable part numbers, connector models, wire specifications, length, Pin definition, and actual assembly compatibility. The cable end connector model corresponding to this scheme is 20680-060T-01, which is a CABLINE®-CA II PLUS 60Pin Plug Housing, and the official materials also list it as a recommended配套 component for this series.

The key is not just that "the more shielding layers, the better" when it comes to high-speed signal lines and whether it is necessary to choose double-shielded ultra-fine coaxial cables.
In high-speed signal transmission applications, "Is it necessary to choose a double-shielded ultra-fine coaxial cable?" is a question that engineers often need to consider when selecting wire materials. In fact, whether a double-shielded structure is needed cannot be simply judged by the word "high-speed" alone. It should be comprehensively evaluated based on transmission speed, signal frequency, cable length, wiring environment, surrounding interference sources, impedance requirements, and the overall EMC design of the entire machine. High-speed signals are more sensitive to impedance continuity, crosstalk, insertion loss, return loss, and external electromagnetic interference. Therefore, the shielding structure of the cable itself is indeed an important factor in signal integrity design, but "double shielding" is not an absolute necessary condition for all high-speed signal applications.
For example, taking the CABLINE®-CA II PLUS system referred to in this proposal, the official I-PEX documentation explicitly indicates that it has ZenShield® Full EMI Shielding full shielding structure and multi-point grounding design, and is also combined with a mechanical locking structure for high-speed signal transmission and EMC control. The official documentation also shows that this connector is compatible with Micro-Coaxial specifications such as AWG36, AWG38, AWG40, AWG42, AWG44, among which AWG40 belongs to the ultra-fine coaxial specifications supported by this series.
Therefore, from the perspective of engineering applications, what truly needs to be focused on is whether the "screening and signal integrity design of the entire high-speed link" is matched, rather than simply judging whether it is necessary to adopt "double screening". If the device has a compact internal space, is surrounded by high-speed digital circuits, wireless modules, or other potential interference sources, and has high requirements for EMI and high-speed signal integrity, then the full-screening ultra-fine coaxial connection scheme has significant engineering value; if the actual application environment has relatively lower requirements for EMI, then selection can be made according to the system test results, cost, space, and reliability requirements.

Three, I-PEX 82997-100B-01-D compatible alternative: ultra-fine coaxial cable assembly solution defined by 40AWG, 60Pin, 1-1 wire position
Our company specializes in the production and manufacturing of extremely thin coaxial cable assemblies. We can provide compatible and alternative cable assembly solutions according to the actual product structure, connector matching, cable specifications, length, and wire position definition for engineering development and procurement. Our company can offer: I-PEX 82997-100B-01-D compatible and alternative cable assembly solutions, using 40AWG extremely thin coaxial wire, with the cable end connector model being 20680-060T-01, and the wire position defined as 1--1, suitable for product designs that have high requirements for cable space, signal transmission, and connection density.
From the perspective of specification correspondence, this scheme is designed around the 60Pin high-speed connection application. In the official I-PEX documentation, 82997-100B-01-D is listed as the CABLINE®-CA II PLUS 60Pin Micro-Coaxial 40AWG, L=300mm, 1-1 cable assembly model; at the same time, 20680-060T-01 is listed as the 60Pin Plug Housing in this series. For engineers, when performing alternative introduction, it is recommended to focus on the connector matching relationship, PCB end matching socket, Pin Assignment, wire length, tolerance, bending path, impedance, and high-speed signal test results; for procurement personnel, it is advisable to pay close attention to the specification consistency of alternative materials, sample verification, mass production capability, delivery time, and long-term supply ability. It should be especially noted that "compatible alternative" should ultimately be based on actual sample assembly, size confirmation, and customer system verification results, and not simply replace directly based on similar material numbers.

IV Selection and Compatibility with Alternative Solutions Reference and Suggestions: From Cable and Connector to Complete Unit Verification for Confirmation
During the selection process of actual projects, if the original design uses I-PEX 82997-100B-01-D, the basic specifications for comparison and confirmation can be 40AWG Micro-Coaxial, 60Pin, 1-1 line position definition, 300mm cable length, and 20680-060T-01 connector. The I-PEX official page also lists 82995-100B-01-D, 82996-100B-01-D, and 82997-100B-01-D, etc., which are 60Pin, 40AWG, 1-1 cable sets, with corresponding lengths of 100mm, 200mm, and 300mm, respectively. Therefore, when the project only involves changes in cable length, further evaluation can be made from the same series specifications.
For alternative solutions, engineers should not only confirm whether "the connector can be plugged in," but also pay attention to the overall performance of the high-speed signal chain. Especially in high-speed applications, the connector, ultra-fine coaxial cable, termination area, PCB routing, and grounding/shielding structure actually constitute a complete signal path. Therefore, it is recommended to conduct relevant verifications such as mechanical dimensions, mating reliability, impedance, insertion loss, return loss, crosstalk, and EMI at the sample stage. Purchasers can then further evaluate supplier introduction from the perspectives of batch consistency, production process, delivery cycle, and cost control after the engineering verification is passed.
From the selection logic perspective, "high-speed" does not necessarily mean that all projects must adopt double-shielded ultra-fine coaxial cables; what is truly important is to choose the matching cable material and shielding scheme based on actual data rates, EMI environment, spatial constraints, and signal integrity requirements. For high-density 60Pin applications using 40AWG ultra-fine coaxial cables, a reasonable shielding structure, stable impedance control, and reliable termination technology are more important than simply increasing the number of shielding layers.

I-PEX 82997-100B-01-D is a 40AWG ultra-thin coaxial cable assembly designed for the CABLINE®-CA II PLUS 60Pin connection scheme, with wire positions defined as 1--1 and a length of 300mm.
