Lifting the Fog on RFOG

Will the cable industry's coming 'Radio Frequency over Glass' standard drive MSOs to put more fiber in their diet?

Lifting the Fog on RFOG

Now that the Society of Cable Telecommunications Engineers (SCTE) (SCTE) is busily developing a tech standard for fiber extensions to cable plants, the big question is just how quickly cable operators will actually install fiber-to-the-home (FTTH) lines.

At Heavy Reading, we're working on a couple of studies to tackle that question. We're also looking into how extensively MSOs will make use of SCTE's still-evolving "Radio Frequency over Glass" (RFOG) standard, which is expected to be completed sometime next spring or summer, and whether RFOG will drive cable deployment of telco-like passive optical network (PON) technologies. Stay tuned for more on that research later this fall.

In the meantime, though, some preliminary answers emerged from a Light Reading webinar that I moderated on RFOG last week. During that webinar, entitled "Fiber Extensions for Cable: An Overview of RFOG," we asked cable operators when they expect to start deploying new fiber additions to their HFC plant.

Nearly one seventh of the respondents, or 13.3 percent, said they plan to begin rolling out RFOG technology before the end of the year. That group may well include Time Warner Cable Inc. (NYSE: TWC), Bright House Networks , Cox Communications Inc. , and Source Cable & Wireless , which have already been extending fiber to select households.

Nearly one quarter of respondents, or 23.5 percent, indicated that they will start deploying RFOG sometime next year. Another 9.2 percent said they will begin the rollouts in 2010. So close to half of cable operators polled, or 46 percent, expect to deploy the new technology within the next two and a third years.

On the other hand, slightly more than one fifth of cable operators, or 20.4 percent, don't think they will launch RFOG until at least 2011. And slightly more than one third, or 33.7 percent, have no plans to deploy the technology right now.

We also asked webinar attendees what they viewed as the biggest obstacles to deploying RFOG. In the poll, the largest portion of respondents, 29.9 percent, checked off a lack of competitive urgency as the biggest barrier. Another 26.2 percent called the technology too costly to implement. Some 21.5 percent of webinar participants said there's insufficient customer demand for RFOG-enabled services. And 15.9 percent said there's no need for the extra bandwidth that RFOG offers just yet.

What these poll numbers tell us is that many cable operators have strong interest in deploying RFOG pretty quickly. But, for a good number of others, the jury is still out. It will be interesting to see how many members of the latter group, if any, become converts to the RFOG cause down the line.

These results also tell us that many cable operators aren't sure yet whether they really need to go the all-fiber route. More than two thirds of respondents said they saw a lack of competitive urgency, consumer demand, or need as the greatest hurdle to deploying RFOG.

My hunch is that all these numbers will shift greatly by next fall, once the SCTE has completed its RFOG standard, cable operators have begun rolling out Docsis 3.0 en masse, and Verizon Communications Inc. (NYSE: VZ) and AT&T Inc. (NYSE: T) have further expanded their fiber networks. Then we'll truly see how quickly cable will put more fiber in its diet.
