Wideband DWDM Transmitter | PL7440DT
The PL7440DT DWDM Wideband RF Link is a high-performance RF over Fiber transmitter designed for long-distance wideband signal transport across 10 MHz to 3000 MHz. It supports high RF input power with controlled distortion performance and is optimized for high CNR and stable signal transmission in dense RF environments. The system is designed for integration within Platinum Series chassis architectures for scalable RF distribution networks.
Features & Benefits
- Wideband RF operation from 10 MHz to 3000 MHz

- Designed for high CNR transmission in long-distance RF networks
- Supports up to 32 dB optical budget with PL7220R25 receiver configuration
- CWDM and 10 mW DWDM butterfly laser technology
- DigiRF control enables full setup, monitoring, and system diagnostics via LCD and SNMP
- IMizer calibration enables IMD/CNR alignment without two-tone testing
- Adjustable IMD control with automatic laser drive optimization
- Hot-swappable transmitter module
- Individual module-level processing
The PL7440DT is engineered for integration within modular RF over Fiber architectures where system-level control, scalability, and operational continuity are critical. It operates within PL7010-based chassis environments, supporting distributed RF transport where multiple modules function as part of a coordinated transmission system rather than standalone links. This makes it suitable for high-density ground station, broadcast, and communication network deployments that require structured RF management across multiple channels.
System operation is managed through DigiRF control architecture, enabling configuration, monitoring, and diagnostics through a front panel LCD interface or SNMP-based remote management. IMizer calibration adds adaptive control of signal linearity by dynamically aligning IMD and CNR performance based on system requirements. Combined with hot-swappable module design and redundant chassis power architecture, the system supports continuous operation during maintenance cycles and evolving network configurations without interrupting RF service continuity.
