More Information
Our new double Platinum L-Band link provides a dynamic solution for multiple downlink applications where chassis capacity is crucial and rack space is limited. The new double link provides modularity and high-performance in a small form factor for superior distance transmission. The Platinum chassis, PL7010C, can be equipped with 12 double link cards offering 24 separate L-Band transportation paths.
Utilizing our 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 sub-rack 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 IMD requirements. The IMizer™ requires the use of a correction factor table above 2.5 GHz.
Each individual transmitter or receiver can be “hot swapped” in the sub-rack chassis maintaining the highest subsystem uptime capability. Each module contains an individual processor to maximize specification performance at all times under demanding user applications.
The PL27220T transmitter and PL27220R4 receiver are designed for sub-rack chassis mounting. The associated Platinum chassis, model PL7010, has 12 active slots, one main control processor (MCP) slot and two redundant power supplies. The PL27220T transmitter and PL27220R4 receiver are optimized for L-Band downlink application. The PL27220 is equipped with separate LNB voltage control.
It features:
- 24 Uplinks or Downlinks per chassis
- Two L-Band RF streams per card
- Transmission distance up to 10km
- Powerful management capabilities via a front panel LCD and rack mounted SNMP
- L-Band of 950–3000 MHz
- Automatic Laser Drive Control IMizer
