EPON supporting DOCSIS from Salira

Apologies to my readers for no updates over the last month-and-a-half, I was busy traveling. There have not been any major updates in our field, except for the news of Salira releasing DOCSIS support for its EPONs.

The idea is to use EPONs as a feeder network for Cable TV networks. DOCSIS 3.0 which has been standardized recently and is still under trial deployment by Comcast and others and support downstream bandwidth is excess of 12 Mbps. PONS seem the natural choice to act as feeder networks.

However, this idea is not new. CATV networks already use fiber as a feeder till the last mile where copper takes over. EPONs have also been suggested earlier as feeder networks to VDSL, whose reach is much shorter. So much is to be seen on how Salira plans to market this.
