DOCSIS Reboot… Everybody is talking about DOCSIS 3.1 and the technology surrounding it. In the coming months I will cover both the emerging technology of DOCSIS and how it impacts our careers, our subscribers and our industry with a focus on DOCSIS 3.1. This is an opportunity to discuss both the technical aspects of the DOCSIS specifications and then discuss the impacts. As an example, when we first introduced quality of service (QoS) in the DOCSIS 1.1 specification there were a lot of items that were not quite tangible.

It's a smart idea that doesn't cost a lot more than a regular splitter and also helps reduce ingress. It's called BarrIER technology by Teleste. BarrIER® technology is an innovative solution for reducing ingress/egress that addresses the complete in-home interconnect domain and solves the problem of maintaining adequate C/N levels. Using BarrIER® will reduce the need for manual maintenance work, greatly reduce operational costs, and incrementally increase service reliability and enhance network performance".

EPON | A Brief Primer

Mia Colabrese2012-12-03T09:00:25-05:00December 3rd, 2012|

EPON Ethernet Passive Optical Network (EPON) is an actual Ethernet network over optical cable following the IEEE 802.3av standard for 1 Gbps (supporting up to 10 Gbps). There are two (2) functional components of an EPON network, an Optical Line Terminator (OLT) and an Optical Network Unit (ONU). The OLT is analogous to a CMTS in a DOCSIS network while the ONU is similar to the cable modem. Data is transmitted to by the OLT to ONUs in the downstream by a broadcast method. Encryption is used, so
