Ultra-fine coaxial cable bundle vs. high-speed ribbon cable: I-PEX 20532-030T-02 application analysis

In the design of high-speed electronic equipment, the selection of wire harnesses directly affects signal quality and product reliability. In recent years, ultra-thin coaxial cables (Micro Coaxial Cable) have gradually become an important option in the design of high-end equipment due to their excellent high-speed transmission capabilities, good anti-interference performance, and high flexibility. Many project designers may face a question when selecting: Can ultra-thin coaxial cables replace traditional high-speed ribbon cables (such as FPC, FFC)? This article will take the I-PEX 20532-030T-02 connector as an example, analyze the performance differences and application scenarios of the two, and help engineers make more scientific selection decisions.

Fine coaxial cable束 VS High-speed flat cable

When selecting harnesses, both extremely thin coaxial harnesses and traditional high-speed flat harnesses have their respective advantages. The following comparison is made from several key aspects:

Transmission speed

The extremely thin coaxial cable bundle supports high-speed signal transmission up to 20Gbps, while traditional high-speed ribbon cables are generally 5-10Gbps. In terms of high-speed performance, the extremely thin coaxial cable bundle has a clear advantage.

Signal Integrity

The ultra-thin coaxial cable adopts a single-core wire plus shielding design, which has strong anti-electromagnetic interference capability and can ensure stable signal transmission; while traditional high-speed ribbon cables lack effective shielding, are prone to interference, and have relatively weaker signal quality.

3. Flexibility and bendability

The extremely thin coaxial cable bundle can withstand over 5000 bends, making it very suitable for applications with limited space and frequent folding; high-speed ribbon cables have limited bending resistance and are prone to breaking.

4. Performance blocking

Extremely thin coaxial cables support shielding at the wire core level or for the entire cable bundle, effectively reducing signal crosstalk and EMI; high-speed ribbon cables are mostly unshielded or only shielded in their entirety, with limited anti-interference capability.

Cost consideration

The manufacturing process of ultra-fine coaxial cables is complex and expensive, making them suitable for high-end products; high-speed ribbon cables are cost-effective and suitable for general applications that do not have high requirements for speed and anti-interference.

In summary, if the product has high requirements for high-speed signals, anti-interference ability, and flexible wiring, extremely thin coaxial cable bundles are undoubtedly the better choice; for low-speed and general applications, high-speed ribbon cables are still economical and practical.
