With a 10 Gigabit Ethernet SFP+ interface, the SFD supports real-time burst upstream and downstream modulation of user data.
Complete Suite of DOCSIS Signals
The SFD supports real-time modulation with DOCSIS 3.1 OFDM and OFDMA burst modulation. Legacy SC-QAM J.83 Annex A/B/C and upstream burst A-TDMA and S-CDMA are also supported.
Simulation of RF Impairments
Emulating real world environments in the lab requires the replication of RF impairments. CLGD simulates AM Hum, Phase Noise, Micro-reflections, Narrow-bandwidth Interferers, and AWGN.
The SFD is designed to work with the DSA and offer advanced functions like Cable Modem Ranging and in plant upstream carrier testing.
