Cisco GainStar 1 GHz Node with 65/87 MHz Split
The Cisco 1 GHz GainStar Node (GSN) is specifically designed to serve in HFC networks.
With its modular design of Optics and RF amplifier electronics, the GSN can provide a full
complement of functions required by advanced networks.
The GSN 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 GSN utilizes GaAsFET technology optimized for superior
distortion performance.
The GSN provides two higher-level RF output ports or four lower-level RF output ports in a strand
or pedestal mount configuration. The GSN can be field-upgradable from a forward only
configuration to a forward and reverse path configuration.
The optical receiver module with a built-in AGC covers a wide optical input range. The AGC
increases reliability and decreases nonlinear distortion. Standard plug-in attenuators can be used
to adjust gain and equalization. Reverse traffic can be combined and routed to an FP, DFB or
CWDM reverse optical transmitter.
Installation of the node is quick and easy. The GSN can be ordered as a complete node or as an
upgrade kit for new 1 GHz GainStar amplifiers.
