Webinar Overview

The major challenge to delivering high speed data, new HD video channels or digital streaming services in a cable system is the limitation on available RF spectrum. The typical RF bandwidth in the majority of HFC networks today is still 750 MHz. DOCSIS 3.1 defined an upper bandwidth limit of 1.8 GHz but only provided specific requirements for operation up to 1.2 GHz. To fend off fiber and future wireless competitors, cable operators need a multi-gigabit-capable symmetrical network with up to 10 Gbps downstream capacity. The CableLabs DOCSIS 4.0 specification initiative will define the requirements needed for operation of the entire 1.8 GHz bandwidth allocation.

There are a number of advantages that 1.8 GHz DOCSIS 4.0 can provide for network operators once it is released early next year. Primary among these is the ability to maintain their existing Frequency Division Duplex (FDD) node plus amplifier cascade architecture as an alternative to the more costly 1.2 GHz Fiber Deep N+0 network design. But there are also significant challenges related to higher coax attenuation loss and other impacts that come with higher frequency operation. This webinar will discuss the benefits and tradeoffs associated with migrating to a 1.8 GHz network along with the new RF components now in development at Mini-Circuits that are needed to meet the exacting requirements for this expanded frequency bandwidth.
