USB Bulk Cable

Key features to make your high-speed usb bulk cable design stand out in OEM factory assembly: We widely adopt an advanced Coaxial structure in our data cable extruding pathways. Compared with standard industrial ‘Twisted Pair Structures’, the bulk usb cable reels we produce feature an ultra-smooth surface, 3-5 times higher flexibility than generic line materials, and a micro-small outer diameter—meeting the compact footprint trends in premium medical device telemetry and rugged industrial computing.

As an ISO-aligned usb cable bulk manufacturer with over 20 years of expertise, we control characteristic impedance strictly within ±2Ω to ensure your data transfer is significantly more stable, distinguishing your brand from commercial off-the-shelf component suppliers

The USB 3.1 specification does indeed define a USB Type-C connector with 21 cores, but in some cases, only a portion of these cores may be used to support USB 3.1 functionality. This is because the USB Type-C connector is highly versatile and scalable, capable of supporting multiple functions and protocols.

In certain USB 3.1 devices or cables, only 16 of these cores may be used to transmit USB 3.1 data signals, while the remaining cores are utilized for other functions such as charging, video output, audio transmission, etc. This design aims to meet different device requirements and provide greater flexibility and functionality expansion.

Although using only 16 cores may not achieve the maximum transfer rate of USB 3.1 (10 Gbps), it can still support high transfer rates (e.g., 5 Gbps) and other features of USB 3.1. Such cables are typically labeled as “USB 3.1” to indicate that they are compatible with some aspects of the USB 3.1 standard.

Therefore, when purchasing USB 3.1 devices or cables, it is recommended to check the product descriptions and specifications to understand their specific features and performance. If you require full USB 3.1 functionality and the highest transfer rate, selecting devices or cables that comply with the USB 3.1 specification and have 21 cores would be preferable.
