Putting the symmetry in DOCSIS and enabling increased bandwidth and speed. Why does symmetry matter you ask, especially in broadband? Well you have symmetry in fiber. Big deal, right? Yes, now FDX allows for coax to do something that it could never do before, have symmetry just like fiber. So FDX continues the alphabet soup of our industry but through symmetry allows for increased broadband and speed in coax. So let’s take another bite of the alphabet soup together. In my last article I covered remote PHY (R-PHY)

The typical subscriber - maybe even you - really likes the concept of apps. Think of how Netflix has transformed our industry. Netflix is really an app that

You heard me right and I’m not quoting Austin Powers here. How is this possible? Okay, let’s review: Subscriber’s unmanaged WiFi networks are causing a ton of customer service representative (CSR) calls and over $1 Billion plus dollars in multiple-system operator (MSO) spending. Subscriber unmanaged WiFi is a big dollar and optics issue for the industry. Most subscribers do

DOCSIS 3.1 - BOOM - Drop the Mic. CCAP and Cable Modems the New Rock Stars in Test We have always known that DOCSIS rocks but it is just so much cooler than we all thought.

DOCSIS 3.1 Beating Expectations, Working and Ready for Service Now

Mia Colabrese2016-12-19T11:18:36-05:00December 19th, 2016|

DOCSIS 3.1 Beating Expectations, Working and Ready for Service Now At this years SCTE Cable Tec Expo, several large MSOs, such as Comcast, made statements that DOCSIS 3.1 is working and it is working with great results. Only the downstream OFDM (orthogonal frequency division multiplexing) portion is currently supported in DOCSIS 3.1 CMTSs. Upstream OFDMA (orthogonal frequency division multiple access) is supported in the CPE side (aka cable modems), but only one CMTS vendor has support for upstream OFDMA. This is really not considered a show stopper, however.
