Yes, the switch is available from two vendors that I know of. They are referenced at [1]. For nodes, we have a page describing what hardware support is needed [2]. Then there are various boards available commercially which implement that hardware support, like [3]. For the particular case of WR-enabled TDCs, one could use the SPEC PCIe carrier [3] with a TDC FMC [4] or a simple DIO FMC [5], delegating then the TDC function to the FPGA on the carrier, using an HDL core like [6]. Or roll your own, of course. Has anybody experienced with free-space optical gigabit Ethernet links? I am curious about whether the transceivers have a fixed latency or at least a latency one can easily quantify online. This is the trickiest part for adding WR support on top of a given physical layer.
