An extremely flexible, modular digital fixed link system, the GL offers a
remote RF head (to 23 GHz) and internal RF modules (to 14 GHz) for fixed
link (STL, TSL, ICR) applications. Through interface modules, the mainframe
can be configured to meet any application now and in the future.
Central to the GL is the internal bidirectional modem card, configurable
for single carrier QAM or COFDM modulation, at rates up to 155 Mbps, in
duplex or split modulation modes. In split modulation, it receives COFDM
on the receiver side while simultaneously transmitting DVB-S QAM. If
configured as a duplex system, an SNMP subchannel provides command
and control and link status without affecting payload.
Optionally, users can select internal RF modules for existing waveguide
installations or external RF Heads (using low cost coax cable) (high and
low power heads available) where long waveguide lengths are expensive
and suffer high losses. This feature can truly maximize link and costs
budgets.
