Princetel’s HDM model converters allow 3G/HD/SD-SDI signals to transmit through a single strand of MM or SM optical fiber. They can extend the transmission distance by 10 km (MM) to 40 km (SM). The devices support 1080p, 1080i, and 720p formats by using 1.485G infrastructure at > 3Gbps data transmission rate. It powers conveniently through mini USB. CWDM (SM fiber) models are also available. Call our tech support if you need to send more than one HD video signals or the combination of video and data through a single fiber. We can offer proven custom solutions.
