Key Features

  • Real-time Generator

    With 2 x 10 Gigabit Ethernet SFP+ interfaces, the CLGD supports real-time modulation of user data.

  • DOCSIS 4.0 Extended Spectrum DOCSIS

    CLGD supports DOCSIS 4.0 Extended Spectrum (FDD) channel loading up to 1.8GHz.

  • Full Duplex DOCSIS (FDX)

    CLGD supports DOCSIS 4.0 Full Duplex DOCSIS (FDX) channel loading with upstream carriers up to 694MHz.

  • Simulation of RF Impairments

    Emulating real world environments in the lab requires the emulation of RF impairments. CLGD simulates AM Hum, Phase Noise, Micro-reflections, Narrow-bandwidth Interferers, and AWGN.

  • Legacy DOCSIS Carriers

    Loads to legacy SC-QAM (J.83 Annex A/B/C), A-TDMA, and S-CDMA can be generated at the same time as DOCSIS 3.1 and more recent OFDM and OFDMA carriers.

  • Analog TV Carriers

    NTSC and PAL analog video carriers are supported from the CLGD to simulate legacy carriers.

STB and Cable Modem Validation

The controllable load generation of the CLGD makes it a powerful tool for test and validation of set top box (STB) and cable modem silicon and products.

HFC Equipment Validation

Fiber nodes, RF Amplifiers, Taps, Splitters, and other equipment that is deployed in HFC networks need to be fully characterized under full channel loading which CLGD can enable in the lab.
