GainStar 1 GHz Mini Node with 42/54 MHz Split
The GainStar Mini Node (GSMN) is a 1 GHz compact size node specifically designed to
serve in fiber-deep HFC networks. The GSMN provides excellent forward and reverse
path performance combined with high reliability and a user-friendly layout. All new
GainStar products share common plug-in accessories and perform to 1 GHz in the
forward path.
The GSMN utilizes GaAsFET technology optimized for superior distortion performance.
The GSMN provides a single higher-level output or two lower-level RF output ports in a strand or
pedestal mount configuration. The GSMN can be field-upgradable from a forward only configuration
to a forward and reverse path configuration.
The GSMN features onboard LEDs to indicate the optical input power. The integrated optical
receiver module with a built-in AGC increases reliability and decreases nonlinear distortion.
Reverse traffic can be combined and routed to an FP, DFB or CWDM reverse optical transmitter.
