Video cables are essential for transmitting audio and video signals between devices, and their length can significantly impact usability and signal quality. Here is a detailed breakdown of the common length specifications available in the market:

Short – Distance Cables

• 0.2 meters: These ultra – short cables, such as the Type – C to DP1.4 female 8K60Hz cables for computers, are ideal for scenarios where devices are placed in close proximity. They are perfect for connecting small portable devices to nearby monitors, reducing cable clutter in limited spaces.
• 0.6 meters: Cables like the Qinguang pure silver braided Lightning to 3.5mm audio cable are convenient for on – the – go use. They are easy to carry and suitable for connecting mobile phones to car audio systems or external sound cards, providing a hassle – free audio experience.
• 1 meter: Widely used in various applications, 1 – meter cables, including 3 – pin XLR male to dual 6.35mm male audio cables and MOKE USB to RS485 converters, offer a balance between flexibility and stability. They work well in most standard device – to – device connections, ensuring a reliable signal transfer without excessive cable length.

Medium – Distance Cables

• 1.5 meters: Cables like the Ugreen Mini DisplayPort to DisplayPort 1.4 cable and the Kaiboer DVI – HDMI cable (version 1.2) are popular choices for office and home entertainment setups. This length provides enough flexibility to connect devices like computers to monitors or TVs, allowing for a more organized cable arrangement.
• 1.8 meters: A common length for many video and audio cables, such as the QiuyeYuan 3.5mm audio splitter cable and the Biyaazi 4K high – definition DisplayPort to HDMI cable, 1.8 – meter cables are versatile and suitable for a wide range of devices. They can easily reach between devices in typical room setups, making them a practical option for most users.
• 2 meters: The AENZR USB – C to DP video cable and some Ugreen DP to Type – C cables in this length are useful when a bit more distance is required between devices. For example, when connecting a laptop to a TV in the living room, a 2 – meter cable offers greater flexibility in device placement.
• 3 meters: Some DP to Type – C cables with a 3 – meter length are designed for scenarios where devices need to be placed further apart, such as in large conference rooms. They can connect a computer to a distant projector, accommodating various room layouts without sacrificing signal quality.

Long – Distance Cables
Cables of 5 meters, 10 meters, 15 meters, 20 meters, and even longer are commonly used in surveillance systems and for connecting devices across large rooms or buildings. For instance, dedicated computer – to – TV audio – video cables are available in these lengths, enabling users to stream content from a computer to a TV in another room. In surveillance, SYV75 – 3 video cables can transmit signals up to about 200 meters, while SYV75 – 5 cables can cover distances of around 500 meters, ensuring reliable video transmission over extended areas.
