DOG-F1 Optical Modem Front-End Digitizer

The DOG-F1 Optical Modem Front-End Digitizer is part of the A-Series, a family of next-generation satellite modem platforms built on versatile FPGA- and software-based architecture. It is designed for optical communication up to multi-GHz bandwidths, supporting the full variety of space missions from LEO to Deep Space. Exceptional analog and digital engineering provides teleport-grade devices with future-proof expandability. Through an all-IP structure, the platform supports both native network operation as well as data streaming over IP. Built-in protocol stacks support an increasing number of space data formats as well as streaming of transparent baseband data and synchronized symbols for user-defined processing and integration into virtualized infrastructures. The DOG-F1 enhances the DOG-M1 Multi-Mission Optical Modem by providing the early stages of signal processing from symbol synchronization to LLR computation for Optical On-Off-Keying (O3K) and High-Photon-Efficiency (HPE) transmissions. Key features include multi-mission support, hard-decision and soft-decision decoding, O3K symbol rates up to 10 Gsps, and support for CCSDS 141.0-B-x and 142.0-B-x.
