VR headset high-speed wiring solution analysis: the perfect combination of I-PEX 20497-026T-30 and ultra-thin coaxial cable

With the continuous breakthrough of virtual reality (VR) technology, head-mounted display devices are accelerating development towards higher resolution, lighter weight, and greater immersion. At the same time, the internal wiring scheme has become one of the key factors affecting device experience. Due to the extremely limited internal space of VR head-mounted displays and the need to carry extremely high-speed video and data transmission, miniaturized and highly reliable connection methods are particularly important. Among various solutions, the combination of extremely fine coaxial cables and high-performance connectors has become the mainstream configuration in the industry. This article will introduce the I-PEX 20497-026T-30 connector and analyze its important value in VR head-mounted display wiring schemes.

What is the ultra-fine coaxial cable (micro coaxial cable)?

A super-fine coaxial cable is a small-diameter cable with characteristics of miniaturization and high-frequency transmission, commonly used in devices with limited space and high requirements for signal integrity. Its core features include:

1. The wire diameter is ultra-fine (about 0.3mm~0.8mm), which is convenient for wiring between high-density modules.

Excellent EMI suppression ability, suitable for complex electromagnetic environment.

Supports high-speed signal transmission, capable of meeting the needs of 4K/8K ultra-high-definition video.

Flexible and suitable for repeated bending applications in dynamic structures such as VR headsets.

Therefore, it is not only adopted in the VR field, but also widely used in a variety of products such as wearable devices, ultra-thin laptops, smartphones, and in-car image systems.
