The CVT10 fiber converter offers a cost-effective way of conversion between optical signals and electrical signals for video sources to connect the sending card to the LED display. Delivering a full-duplex, efficient and stable data transmission that is not easily interfered with, this converter is ideal for long-distance transmission. The CVT10 hardware design focuses on the practicality and convenience of the on-site installation. It can be mounted horizontally, in a suspended way, or rack mounted, which is easy, secure and reliable. For rack mounting, two CVT10 devices, or one CVT10 device and a connecting piece can be combined into one assembly that is 1U in width.
