L-Band Long Distance Up And Down Links | PL7220 / PL7230
Global Foxcom’s Platinum L-Band links deliver high-performance long-distance RF transmission across 950 to 3000 MHz, supporting distances up to 100 km. Low-profile, hot-swappable transmitters and receivers mount in the Platinum PL7010 chassis with two redundant power supplies.
Features & Benefits
- L-Band frequency range 950–3000 MHz
- Transmission distance up to 100 km
- Optimized versions for uplink and downlink applications
- Front-panel LCD and SNMP-based management
- LNB power control selectable at +13 V or +18 V
- CWDM and DWDM options for multiple L-Band channels on a single fiber
PL7220 and PL7230 links are built for long-distance L-Band transport across uplink and downlink paths. Low-profile, hot-swappable modules mount in the PL7010 chassis with twelve active slots and two redundant power supplies. DigiRF™ provides control and monitoring from the front-panel LCD and through SNMP-based management for setup, status, and alarms. IMizer™ automatically calibrates the link by adjusting laser drive to the selected IMD target and maintaining CNR without a two-tone test, locally or remotely. CWDM/DWDM options support multiple L-Band channels on one fiber, and selectable LNB power at +13 V or +18 V is available via LCD or SNMP.

What L-Band range do these links support?
They operate across 950 to 3000 MHz, suitable for both uplink and downlink paths.
What is the maximum supported distance?
These L-Band links support long-distance operation up to 100 km, with optical and wavelength options selected per site design.
What is the difference between PL7220 and PL7230?
PL7220 is optimized for downlink levels, while PL7230 is optimized for uplink. Typical operating input ranges differ: downlink paths handle about −25 to −50 dBm, while uplink paths handle about +5 to −25 dBm.
Can multiple L-Band channels share a single fiber?
Yes. CWDM and DWDM configurations support multiple channels on one fiber for higher capacity.
Which chassis is required?
Both links mount in the Platinum PL7010 chassis, which provides twelve active slots and two redundant power supplies.
