The Aurora VHub performs all the functions of a fully operational hub in a node housing, enabling MSOs to quickly and cost-effectively implement hubs wherever needed, and no longer limited by real estate considerations. Indeed, the VHub moves the functionality of an indoor hub to a weather-proof node enclosure that can be sited closer to the optical nodes in the network. VHubs, which can be strand- or pedestal-mounted, can be configured in a great variety of ways with a wide assortment of standard plug-in modules.

Aurora's VHub technology saves money for MSOs in many ways:

• No need to locate (or use existing) real-estate


• No need for HV air conditioning


• No need for generators


• No need for building permits.

All this results in significant cost-savings and ultimately a reduced time to market.

Aurora's VHubs offer the following features and benefits:

• Service for up to 20,000 households from a single VHub location, providing broadcast and narrowcast services for up to 24 nodes using as few as six fibers (including redundant routes for broadcast/ narrowcast and return fibers) when used in conjunction with Aurora's DWDM return path transponders


• Cost effective service for multiple small markets from a single controlled VHub


• Low fiber consumption, enabling 24 nodes to be served by as few as two fibers


• Deployment of EDFAs without costly environmentally-controlled facilities or cabinets, and overcome passive optical splitting and combining losses to create broadcast/narrowcast feeds for 16 to 24 downstream nodes.


• Support for up to 12 plug-in modules (including FA4500 series EDFAs, OP4528/OP4538 Broadcast/Narrowcast Combiners, OS42S1S Optical Switches, OE4130S Monitoring Transceivers, DS4004 Optical Ethernet Multiplexers, DT4000 series Digital Transceivers, and DX4500 series Digital Transponders)


• Full monitoring and control via Aurora's Opti-Trace EMS software


• Provisioning redundancy and route diversity with switching times less than 20 milliseconds (typically <5 milliseconds)

Typical applications for the VHub include:

• Elimination of a hub or OTN cabinet


• Centralization of video servers and CMTSs


• Network extension


• Fiber reclamation


• Fiber on Demand™ deployment


• RFoG deployment
