Foxcom’s Platinum Wideband products are designed to meet the increasing demand for modularity and high-performance in a small form factor for superior long-distance transmission. With high RF input power and wide dynamic range, the link is designed to provide full specification service up to a full 4 dB optical budget with the PL7440R4 receiver.
Utilizing 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 PL7440T transmitter and PL7440R4 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.
