It is now well established that X-ray emission is a common feature of kiloparsecscale radio jets (see Harris & Krawczynski 2006, for a recent review and the associated website, http://hea-www.harvard.edu/XJET/). The spectral energy distributions (SEDs) of the powerful quasar jets are predominantly characterized as “optically faint”, with the spectra rising between the optical and X-ray bands. C...
