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 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. 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: • More data bandwidth per user • More voice channels per modem • More users per fiber node Broadcom®, the pulse logo, PROPANETM, and Connecting everything® are trademarks of Broadcom Corporation and/or its subsidiaries in the United States and certain other countries.
