Datasheet PDF


The DMD1050T L-Band Satellite Modem board offers a complete modem with FIPS certified TRANSEC on a compact PCB daughter board. The embedded TRANSEC capability is fully compatible with the TRANSEC capabilities in Comtech EF Data’s DMD2050E and SLM-5650A Satellite Modems. The compact size is engineered to be a drop-in replacement option for the TDMA modem card in many current fly-away terminals. The conductively cooled design enables fly-away terminal vendors to meet demanding outdoor environment requirements without the need for fans or custom heat sinking design. With standards including MIL-STD-188-165A, IESS-308, -309, -310, -314/315 and DVB, and covering data rates up to 20 Mbps, the DMD1050T covers virtually all your satellite IP, telecom, video and Internet applications.

The extensive list of integrated hardware and software options give you the ability to integrate the modem on many platforms and provide an upgrade path for future networks. Options may be purchased with the product or easily upgraded in the field through the web browser or terminal port.
