For engineers, ultra-fine coaxial cables are not limited to transmitting a single signal; they can also transmit multiple signals simultaneously by being composed of multiple independent coaxial cables into a cable bundle. The basic principle is that each ultra-fine coaxial cable can act as an independent signal transmission channel, and then multiple channels are aggregated through a multi-Pin connector, making it very suitable for high-density, high-speed data transmission systems. Taking the I-PEX CABLINE®-CA series as an example, this connector uses a 0.4mm contact spacing and offers specifications such as 10Pin, 12Pin, 20Pin, 30Pin, 40Pin, 50Pin, and 60Pin, which can be configured according to the actual number of channels in the system. For the I-PEX 82667-100B-01-D introduced in this article, it is a 40Pin Micro-Coaxial ultra-fine coaxial cable bundle using AWG#40, 50Ω ultra-fine coaxial cable, with a length of 300MM. The connections at both ends are made in a 1-1 manner, that is, Pin 1 on one end corresponds to Pin 1 on the other end, and so on. Therefore, from the perspective of engineering design, it can concentrate multiple high-speed signals into a compact ultra-fine coaxial cable bundle for transmission, rather than relying on a single cable to carry all the signals.
When laptops, industrial cameras, AI vision equipment, high-resolution display devices, and other high-speed electronic products need to simultaneously transmit multiple data streams within a limited space, engineers typically need to consider signal rate, crosstalk, wiring space, impedance control, and connection reliability simultaneously. Traditional wiring or ordinary wires may increase the difficulty of system design in multi-channel high-speed transmission scenarios as the number of channels increases. Ultra-fine coaxial cables, using a coaxial structure, have each channel with relatively independent transmission structures, which is beneficial for high-speed signal channel design. The CABLINE®-CA connector itself employs a 0.4mm Pitch horizontal insertion structure, with a mating height of approximately 1.0±0.1mm, and supports high-speed transmission applications up to 32Gbps/Lane PAM4, thus enabling high-density multi-channel connections in a smaller space. For engineers, this means that when designing high-speed displays, camera data, or other high-speed digital signals, they can choose an appropriate number of pins for ultra-fine coaxial cable bundles based on the actual number of signals. For purchasers, it is crucial to ensure that the pin count, wire diameter, impedance, length, pin assignment, and connector model are fully matched with the original design, rather than simply replacing based on "how many pins".
I-PEX 82667-100B-01-D is the product material number/model of the 40Pin ultra-thin coaxial cable assembly product introduced in this article, and its corresponding cable end connector main model is 20634-140T-02, with a cable length of 300MM. From the product structure, this solution adopts the CABLINE®-CA series 40Pin connection scheme, with cable material of AWG#40, 50Ω Micro-Coaxial ultra-thin coaxial cable, and uses a 1-1 Pin Assignment. For devices that require simultaneous transmission of multiple signals, this combination of "multiple ultra-thin coaxial cables + multiple Pin connectors" can integrate multiple signal channels into a single cable assembly while maintaining a high wiring density. It should be particularly noted that "40Pin" does not mean that it can unconditionally carry 40 fully identical high-speed signals; the actual transmittable signal types, differential pair count, power/ground wire allocation, and high-speed performance still need to be confirmed in combination with specific Pin Assignment, system protocol, PCB routing, and the overall SI/PI design. Therefore, engineers should use the original design's electrical definitions and actual test results as the final judgment basis when introducing alternative cable assemblies.
If engineers or purchasing personnel are looking for a compatible alternative for I-PEX 82667-100B-01-D, it is recommended to first confirm the key parameters such as the number of 40 pins, 0.4mm pitch connector system, matching relationship of 20634-140T-02 cable end connectors, AWG#40 cable, 50Ω impedance, 300MM length, and 1-1 Pin Assignment of the original cable assembly. Then further confirm the actual high-speed signal types and channel allocation required by the equipment. Especially for high-speed signals such as USB, DisplayPort, eDP, MIPI, etc., when transmitting multiple channels simultaneously, it is not only necessary to pay attention to whether the connectors can be inserted, but also to the impedance continuity, differential pair layout, crosstalk control, cable length consistency, termination technology, and batch production consistency.
