The ODM/R‐840 features a 10/100/1000 Gigabit Ethernet (GigE) interface and provides WAN
bandwidth optimization. It also features integrated VersaFEC, a patented system of short‐block
codes that provide maximum coding gain with lowest possible latency.

1.2 ODM/R-840 Functional Description
The ODM/R‐840 transmits VersaFEC interoperable with Comtech EF Data’s CDD‐880 Multi‐
Receiver Router. The receive side supports DVB‐S2 operation at L‐Band up to 62 Msps, and is
compatible with Comtech EF Data’s CDM‐800 Gateway Router for Constant Coding and
Modulation (CCM) operation.
The unit features a high performance processor and a real‐time operating system (RTOS)
combined with multiple Field Programmable Gate Arrays (FPGAs).
The unit runs on an embedded operating system in non‐volatile Flash memory. It does not have
moving parts for media storage.
The unit supports reception and transmission of IP data over satellite links via two fundamentally
different types of interface – IF and data:
• The IF interface provides a bidirectional link with the satellite via the uplink and downlink
equipment.
