C-Band, Extended C-Band, X-Band, and Ku-Band Interfacility Link Specifications
These links carry the main transmit and receive signals between the equipment room and the antenna site. Each
fiber-optic path carries one entire polarization. One fiber is used in single strand links and two are used in 1:1
redundant paths. Or, the path may share a fiber-optic link with another path in 1:2 redundant configurations. Each
link is designed to meet and exceed all of the requirements for use in Intelsat Standard A earth stations, even
under conditions of heaviest signal loading.

* Spur-free dynamic range (SFDR) = 2/3(IP3 – NF + 173.8) dB/Hz^2/3; IP3 = input third-order intercept, NF = noise figure. SFDR is the range
where the carrier is above the noise and the third IM is below the noise, C/I = 2x(IP3 – PIN), where PIN = input RF/carrier for two carriers.
