Figure 7. XPIC configurations.
Figure 7, top, shows a basic XPIC 1+0 (could be called XPIC 2+0 as well). It uses a single channel pair, two
polarizations and four modems per hop over a single antenna per site. Double capacity is achieved without
using any extra spectrum. Note: 1+0 XPIC partial protection for aggregated packet traffic is not automatic.
When a fault occurs preventing the use of XPIC, the interfering transmitter has to be manually muted
(either locally or remotely) in order to remove the interference and allow maximum speed operation of the
remaining modem.
