Compact Broadband Node CBN1222/CBN1224 is designed to meet the
growing need for bandwidth. The node provides advanced features and benefits and
helps operators reduce operating costs by simplifying DOCSIS 3.1 deployments and
network upgrades.
helps operators reduce operating costs by simplifying DOCSIS 3.1 deployments and
network upgrades.
The node makes use of the latest developments in gallium nitride (GaN) monolithic microwave integrated circuits
(MMICs), bringing excellent RF performance at a lower power consumption (compared to GaAs
– Gallium Arsenide
technology). It can be configured electronically for rapid initial setup or for adjustments that are needed as network
requirements shift. All settings can be done without service interruption, an especially important capability in
networks that deliver real-time interactive services such as voice over IP (VoIP) and high-speed data transmission.
The node provides flexible options because of its large optical input range and high RF output level. Thus, it can
work with a large variety of reverse transmitters to support a variety of applications within the network.
The number of plug-ins has been minimized to help operators keep inventory and costs down. The full-range
electronic attenuators and equalizers offer improved versatility and make it possible to achieve the same
adjustment range as with conventional plug-ins or potentiometer solutions. A plug-in diplex filter is used to
determine the forward/reverse band split.
To meet future demands for more bandwidth, the node can be configured in the forward band for 1 GHz or 1.2 GHz
for bandwidth extension and reverse path that can be upgraded to 204 MHz.
The Cisco Compact Broadband Nodes CBN1222/CBN1224 (Figure 1) can be configured with a status-monitoring
transponder (EuroDOCSIS/DOCSIS) to enable remote monitoring of critical node parameters and remote control of
the built-in three-state reverse switch.
