Foxcom, a Division of OnePath Networks

Foxcom’s Platinum PL7440DT DWDM Wideband Transmitter is designed to meet the increasing demand for superior long-distance transmission with High CNR. With high RF input power and wide dynamic range, the Transmitter is designed to provide full specification service up to a full 32 dB optical budget with the PL7220R25 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.

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 PL7440DT transmitter is a compatible Platinum chassis mounted device. 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.
