Wideband Dual Downlink and Uplink | PL27440R4

Features & Benefits

  • 24 Wideband uplink and downlink signals per chassis
  • Wideband: 10–3000 MHz
  • More than 8Km. distance [15Km with the PL2-7440T 1550]
  • Powerful management capabilities via a front panel LCD and rack mounted SNMP
  • User control and setting of required IMD level
  • 1550nm and CWDM ITU Grid laser options are available for longer fiber runs and single fiber multiplexing solutions


Global Foxcom’s dual Wideband RF links provide a dynamic solution for multiple uplink and downlink applications where chassis capacity is crucial and rack space is limited. The dual link provides modularity and high-performance in a small form factor for superior distance transmission. The Platinum chassis can be equipped with 12 double-link cards offering 24 separate transportation paths.

Utilizing Global Foxcom’s DigiRF technology, the user has full control of all important functions for setup, operation, and analysis via the front panel LCD or via the associated subrack SNMP capability.

In addition IMizer, an automated adjustable link calibration embedded system enables the user to align the RF links IMD/CNR to specific linearity performances without a two-tone test. Select the desired IMD for the optical transmitter, either locally or remotely, IMizer automatically adjusts the laser drive to meet the IMD requirements. The IMizer requires the use of a correction factor table above 2.5 GHz.

Each low profile individual transmitter or receiver can be “hot swapped” in the subrack chassis maintaining a best subsystem uptime capability. Each module contains an individual processor to maximize specification performance at all times under demanding user applications.

The PL2-7440T transmitter and PL2-7440R4 receiver are designed for subrack chassis mounting. The associated Platinum chassis, model PL7010, has 12 active slots, one main control processor (MCP) slot and two redundant power supplies. No fans are required even under full subrack loading and full LNB powering.
