CoaXPress Cables
CoaXPress is a new digital transmission standard that allows high speed data from a
device, such as a camera, to be transferred to a host, such as a frame grabber. Each
CoaXPress link supports up to 12.5 Gbps data rates, along with device power up to
13W and device control at up to 30 Mbps – all on a single coax cable. For very fast
devices, the links can be aggregated to provide multiples of the single coax
bandwidth. Long cable lengths are supported – up to 30 meters at 12.5Gbps and
over 100 meters at 3.125 Gbps.
Table 6 gives an overview of typical link performance at room temperature for the
link between two FMX II CoaXPress boards, using the downlink channel, uplink
channel and power transmission simultaneously.
