Exciting news! We're moving to a new website over the next few months. As you navigate, you may see a mix of new and old pages.

Key Features

  • Real-time Generator

    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.

  • DOCSIS Eco-System

    The SFD is designed to work with the DSA and offer advanced functions like Cable Modem Ranging and in plant upstream carrier testing.

STB and Cable Modem Validation

The carrier from the SFD can be used as a channel under test for development and validation of set top box (STB) and cable modem silicon and products. When paired with the DSA, the SFD can range DOCSIS cable modems for manufacturing CM validation.

HFC Equipment Validation

Fiber nodes, RF Amplifiers, Taps, Splitters, and other equipment that is deployed in HFC networks need to be fully characterized and the SFD offers an ideal channel under test this characterization.

HFC Operators

HFC network operators can now use the SFD to generate burst upstream carriers at any part of their network and analyze its performance using the DSA.
