Wideband 8Km RF Link | PL7440T / PL7440R4
The PL7440T and PL7440R4 from Global Foxcom’s Platinum Series are wideband RF over fiber links for 10 to 3000 MHz. With a 4 dB optical budget, the link supports precise operation on site runs beyond 8 Km for professional RF applications.
Features & Benefits
- Wideband 10 to 3000 MHz
- More than 8 Km distance with 4 dB budget
- Up to 15 Km with PL7440T1550
- Front panel LCD and rack mounted SNMP
- User control of IMD level
- Hot swappable modules
- Variety of RF and optical connectors
- CWDM ITU grid and 1550 nm options for longer runs
- Single fiber multiplexing support
Built for demanding RF paths, PL7440T and PL7440R4 move wideband signals over fiber with clean, linear performance and strong headroom, fitting neatly into RF over Fiber solutions for campus and facility links. Low-profile modules are hot-swappable and mount in the Platinum PL7010 chassis with redundant power supplies. With DigiRF™ control from the front-panel LCD and SNMP-based management, operators can handle setup, status, and alarms locally or remotely. The embedded IMizer™ calibration aligns IMD and CNR to the selected linearity target without a two-tone test. Optional CWDM on the ITU grid and 1550 nm variants enable single-fiber multiplexing and longer distances when required.

Which chassis does this link use?
The PL7440T and PL7440R4 install in the Platinum PL7010 chassis with redundant power supplies, and the modules are hot-swappable.
Can the reach extend beyond 8 Km?
Yes. Use the PL7440T1550 option to support distance of about 15 Km within the same architecture.
Can several RF paths share one fiber?
Yes. CWDM on the ITU grid allows multiple paths on a single strand when fiber is limited.
Can modules be replaced while the path is active?
Yes. Both transmitter and receiver are hot swappable so maintenance can proceed without taking the link offline.
How do operators check status and alarms?
Use the front panel LCD for local checks or SNMP for remote access to view optical power, basic RF status, and alarms.
