Revolutionizing Capacity

increases broadband network capacity. Operating exclusively

with Broadcom DOCSIS/EuroDOCSIS silicon, PROPANE

increases capacity and reduces delay by using patent-pending

efficiency and latency reduction algorithms for optimal

transmission of voice and data over broadband pipes.

PROPANE is based on application-aware, streaming

architecture that significantly reduces overhead to increase

throughput and reduce latency.

With Broadcom PROPANE, the cable operator can triple the

capacity of the shared return path compared to conventional

DOCSIS/EuroDOCSIS modems. This valuable extra capacity

enables MSOs to provide:

Scalable Solution

PROPANE software dramatically increases last-mile capacity

of the existing broadband network. This increased capacity

becomes even more important when future node splits are

required due to total subscriber growth. In high-growth

markets cable operators often implement quad-splits, so that

four fiber nodes service the same area that a single node served

before the split. When this happens, PROPANE benefits scale

right along with it. PROPANE enables a 3× increase in

reverse path capacity as the network grows. In many cases,

these future capital requirements can also be subscriber

funded. Adding PROPANE to the initial system allows the

MSO to increase subscribers and revenue without significant

capital outlays—providing advance funding for future node

splits and other network upgrades.
