Product description
The Cisco GS7000 Intelligent Node is the latest addition to the 1218-MHz GS7000 Node platform family. This node leverages the recent technological advances of the GS7000 platform and introduces significant operational efficiencies through remote setup and troubleshooting. The Cisco GS7000 Intelligent Node will utilize the cloud-based Cisco Intelligent Node Manager to communicate with the network core for setup as a network element.
The Cisco® GS7000 1218-MHz 4-Port Fiber Deep Intelligent Node deployed with the Cisco Smart PHY Model 120 1x2 iRPD (Remote PHY Device) module has the following Intelligent Node Features
● Highest Output capable Gallium Nitride (GaN) gain stages
● Compatible with Cisco Model 120 1X2 Smart PHY module for Intelligent Node
● Integrated, software controlled electronic accessories (attenuator pads, equalizers, signal directors) for node setup and balancing
● Local node setup, control, and troubleshooting via a smart device (iPhone or Android) and the Cisco Intelligent Node app
● Individual port forward and reverse spectrum capture reduces the need for additional expensive network test equipment. Spectrum is displayed on the LCM Smart Device or remote terminal
● Individual port power saving mode available. The intelligent node is capable of reduced power consumption at each port and complete shutdown of unused ports
● Independent local or remote port setup for output power and tilt
● Remote node access via Cisco Intelligent Node manager for node setup, monitoring, and troubleshooting
● Fiber entry ports on both ends of housing lid
● Fiber management tray and harness for easy access to fiber connections
● Primary and (optional) redundant power supplies with passive load sharing
● Single or dual AC power supply configuration available. Split AC power input available with dual AC Power Supply configuration
● Spring-loaded seizure assemblies to allow coaxial connectors to be installed or removed without removing amplifier chassis
● Enhanced node security via a software-controlled lockout feature
● Element management via the Remote PHY device
● Easy forward and reverse RF split changes

Notes:
1. Forward performance is for the station from the output of the optical receiver or RPD to the node RF output port (including OIB).
2. The reference output tilt and internal tilt are both linear tilt.
3. The forward reference output tilt specified is set by linear I/S equalization in conjunction with the internal tilt of the launch amplifier.
4. Reverse performance is for the station from the reverse input port to the input of the RPD module, with 0 dB reverse input attenuation.
5. Forward Noise Figure is measured with the OIB attenuator set at 0 dB.
