I-PEX 83035-100B-01-D CABLINE®-UA II 44AWG/50Ω series ultra-thin coaxial cable replacement

What requirements do 8K image transmission place on the cable束?

With the development of 8K displays, high-definition cameras, machine vision, AR/VR, and high-resolution image devices, the amount of data for image transmission continues to increase, making it increasingly difficult for traditional wiring to balance high density, high-speed transmission, and spatial layout. For engineers, what truly matters in 8K image transmission is not whether "the wires can simply transmit 8K," but whether high-speed differential signals can maintain sufficient signal integrity within a limited space, including impedance continuity, insertion loss, return loss, crosstalk, and EMI control, etc. Taking 8K 60Hz RGB 4:4:4 10bit as an example, the amount of effective pixel data alone has reached about 59.7Gbps, so actual products usually need to complete data link design through multi-lane transmission, coding, or compression, etc., according to specific interface standards. The advantage of extremely thin coaxial cables lies in their ability to independently control the coaxial structure of each high-speed signal, balancing high-speed transmission, flexibility, and shielding performance in a smaller outer diameter. I-PEX's CABLINE®-UA II adopts a 0.3mm pitch, vertical right-angle structure, and is designed for space-limited, high-speed signal, and EMI shielding applications; the reference standards listed in the official materials include USB 3.1 Gen1, V-by-One HS 1.4, and HDMI 1.3.

I-PEX 83035-100B-01-D: ultra-fine coaxial cable assembly solution with 32P, 44AWG, 200MM

This product model introduced is I-PEX 83035-100B-01-D, which belongs to the CABLINE®-UA II 32Pin Micro Coaxial Harness. It uses 44AWG ultra-fine coaxial wire material, with a cable length of 200MM and a 1-1 termination structure; the connector model used at the cable end is 20497-032T-30. According to the official model data of I-PEX, 83035-100B-01-D corresponds to 32Pin, 44AWG Micro Coaxial, L=200mm, 1-1 structure, and is one of the evaluation harness models in the CABLINE®-UA II series. CABLINE®-UA II itself uses a 0.3mm terminal spacing, supports 26/32/40/50Pin, and is applicable to AWG42, AWG44, AWG46 Micro Coaxial Cable. The official provided mating height is about 1.27±0.1mm. For notebook display modules, cameras, machine vision, portable display devices, and other compact high-speed electronic devices, this 32P/44AWG/200MM combination can form a good engineering match between the number of signals, cable size, and wiring flexibility.

Why can extremely thin coaxial cables be used for high-resolution image transmission?

The core value of extremely thin coaxial cables is not merely "thinner line diameter," but rather the formation of a relatively stable transmission structure through the center conductor, insulating layer, shielding layer, and outer sheath, which controls the external interference and mutual crosstalk that high-speed differential signals encounter during transmission. For applications with high data volume such as 8K, engineers need to focus on the signal integrity of the entire chain, including the inherent characteristic impedance of the cable material, connector termination, cable length, bending status, PCB routing, and grounding structure. CABLINE®-UA II adopts a shielding and multi-point grounding design, and I-PEX officially positions it as a Micro-Coaxial Connector with good EMI performance; at the same time, its Plug size is small, and the official documentation also shows an application example of a 26Pin cable harness made with coaxial cables of approximately 0.29mm outer diameter passing through a Φ2.65mm pivot hole. Therefore, in 8K display or high-speed image equipment, extremely thin coaxial cable harnesses are more suitable for short-distance internal interconnection of multi-channel high-speed differential signals, but whether they can ultimately meet specific 8K interface requirements should still be verified based on specific protocols, Lane numbers, speed, cable impedance, and actual measured SI data, rather than solely based on the application name "8K."

Selection, compatibility, and alternative solutions reference and suggestions

For engineer selection, the key matching information for I-PEX 83035-100B-01-D can be summarized as: CABLINE®-UA II series, 32Pin, 44AWG Micro Coaxial, 200MM length, 1-1 structure, and wire end connector 20497-032T-30. If the original project design uses this model, when considering domestic substitution or second supplier development, it is recommended to prioritize confirming whether the connector series and Pin number are consistent, and then check the wire AWG, characteristic impedance, outer diameter, length, termination direction, shielding structure, and grounding method. At the same time, verify the actual transmission capability through tests such as insertion loss, return loss, crosstalk, and high-speed error rate. For procurement personnel, it is important to confirm whether the substitute product can maintain the mechanical dimensions, connector matching relationship, and cable length consistent with the original drawings, and to evaluate suppliers based on batch consistency, delivery time, cost, and quality control capabilities. Our company can provide I-PEX 83035-100B-01-D compatible substitute cable solutions, and can produce and develop extremely fine coaxial cables according to the customer's original connector, wire specifications, length, and termination structure, helping customers reduce the risk of single-brand supply and providing domesticized cable matching solutions for high-speed display, camera, and precision electronic equipment.
