DVI over Twisted Pair Transmitter Over 1 STP Cable

Ideal Use Cases

The Kramer PT-571HDCP is designed for a clear, specific task: transmitting a DVI signal over one shielded twisted-pair cable. It fits DVI signal paths where the source and receiving equipment cannot be connected conveniently with a direct DVI run and a twisted-pair link is preferred. At the source end, the transmitter converts the DVI signal into the DGKat twisted-pair format. At the destination, a PT-572HDCP+ converts that signal back to DVI. This makes the model relevant to point-to-point DVI extension designs that specify Kramer DGKat technology.

Why Choose This Model

The PT-571HDCP combines a compact transmitter format with DVI conversion, DGKat twisted-pair transmission, and HDCP 2.2 support. Its one-cable STP design keeps the signal path focused: one transmitter converts the source signal, one twisted-pair cable carries it, and the matching receiver restores DVI at the destination. The listed 4.95Gbps bandwidth and 60Hz refresh rate provide concrete performance references when comparing this model with the requirements of a planned DVI system. The product title also identifies the transmitter as a PoC, long-reach model, although no specific transmission distance or power specification is supplied.

Installation and Integration

Integration centers on a paired transmitter-and-receiver arrangement. Install the PT-571HDCP at the DVI source side, carry its converted signal over one STP cable, and use the PT-572HDCP+ at the receiving side to convert the twisted-pair signal back to DVI. The receiver is identified as the matching conversion component, but the source data does not state that it is included with the transmitter. Cable references supplied with the product data include BC-UNIKAT CAT6A U/FTP bulk cable and C-UNIKAT CAT6A U/FTP cable assemblies for DGKat applications. Their listed cable lengths should not be treated as the guaranteed transmission range of the PT-571HDCP because a maximum device extension distance is not provided.

Performance Highlights

The available technical data specifies a bandwidth of 4.95Gbps and a refresh rate of 60Hz. HDCP 2.2 is identified in the product title, making content-protection compatibility an explicit feature of this transmitter. The unit handles DVI at the source and converts it for DGKat transmission over twisted pair; the paired receiver performs the reverse conversion. No native resolution, maximum resolution, audio capability, latency figure, or supported-format list is stated, so system compatibility should be assessed using the documented DVI, HDCP, bandwidth, and refresh-rate requirements rather than assumptions about unlisted formats.

What Makes It Different

This model is distinguished by its narrowly defined role as a compact DVI-to-DGKat transmitter using one STP cable. It is not presented as a general-purpose HDMI, wireless, or network-streaming device. Instead, it serves as the source-side component of a dedicated DVI extension pair with the PT-572HDCP+. That division of functions gives system designers an explicit conversion path from DVI to twisted pair and back to DVI. The related PT-571HDCP-MD is identified separately as the version certified for medical applications; that certification is stated for the MD variant and should not be attributed to the standard PT-571HDCP.

Final Assessment

The PT-571HDCP is a focused choice for a DGKat-based DVI extension path requiring transmission over one STP cable. Its key documented attributes are compact construction, DVI-to-twisted-pair conversion, HDCP 2.2, 4.95Gbps bandwidth, and a 60Hz refresh rate. It should be planned as part of a two-device link with the PT-572HDCP+ receiver. For a correct system design, confirm any requirements not included in the supplied data, particularly maximum resolution, transmission distance, connector details, power requirements, and whether the matching receiver and cable are purchased separately.
