I recently joined a SCTE webinar my colleague, Joerick Santiago, who was presenting on the different methods for mitigating and eliminating Optical Beat Interference (OBI) from your RFoG network. As the number of subscriber being added to FTTH networks utilizing RFoG continue to rise, the risk for a poor customer experience rises with it due to the increase in upstream traffic, often times simultaneously, from multiple subscribers. Ultimately, this traffic occurring at the same time can lead to disruptions in service, which leads to customer service calls and costly troubleshooting. In a worst case scenario, it can lead to loss of subscribers if the problem is not resolved.
It was interesting to me that regardless of your deployment model, pure RFoG or a hybrid RFoG/EPON, OBI is still a threat to your subscriber’s experience. Joerick went on to explain the different solutions available today for OBI mitigation – wavelength randomization, active splitter, selectable upstream - bringing to light the pros and cons associated with each.
The Open SD-Access Network: Why Now? +
As a number of factors converge to herald a new software defined shift, and with SD access becoming mainstream, software defined networks (SDN) and network function virtualization (NFV) are increasingly working their way into the wider communications discussion.
But what does it mean for service providers? Why is now the right time to embrace it?
While the terms SDN and NFV are bandied around, the lack of industry education around them poses a potential barrier when trying to link the potential of this new technology and the way we do business more widely.
What this means for how we do business
As the world becomes increasingly digital, it’s impossible to ignore how SD access might influence a large-scale shift to a much more inclusive, flexible and fair way of doing business. Read More
Hope You Like the Color of Your Next Gigabit Broadband Gateway +
New broadband technologies are constantly evolving and that’s a good thing. As consumers, we need innovation providing us both cost reduction and capability expansion to keep up with our demand for more bandwidth and support emerging residential and business services. Over the last few decades we have seen first generation wireless networks and cell phones go from supporting only voice to smart phones and 4G networks supporting voice, data and streaming video--amazing stuff that drives us to line up at the store every year for an iPhone or Android with better battery life, bigger screens, and more memory to support new applications.

ADTRAN RFoG Beats OBI without Cabinets +
Optical Beat Interference mitigation provides MSOs ability to scale fiber broadband without boxing them in with the need for centralized cabinet expense BERLIN--(May 30, 2017)—ADTRAN®, Inc., (NASDAQ:ADTN), a leading provider of next-generation open networking solutions, today announced its Radio Frequency over Glass (RFoG) solution with Optical Beat Interference (OBI) mitigation technology. This RFoG solution accelerates an MSO’s FTTH initiatives by supporting the reuse of existing CATV assets within both the headend and home. This greatly extends the return on investment cycle while smoothing the transition from hybrid fiber coax and CATV-based triple play to Gigabit FTTH and IPTV-ready deployment models. As RFoG deployments increase in density, the likelihood of OBI occurring greatly increases. OBI is caused by simultaneous upstream optical transmissions by multiple cable modems leading to impaired reception at all upstream frequencies impacting key applications like voice, live video and social media. “The need to support reliable voice and ultra-fast broadband is key to securing lucrative triple play revenues for MSOs in a changing competitive landscape,” said Erik Keith, principal analyst, GlobalData. “As MSOs look to build out their fiber infrastructure to support rich video content, ADTRAN RFoG OBI solutions allow them to deliver the requisite customer experience while…Read More
