The Thirty Years War – Everyone Wins As Cable, Telcos Continue to Battle


As the title indicates, passive optical networks (PONs) are methods of distributing signals without any active equipment. This is appealing to provider vendors since chucking the lasers cuts prices and can make the resulting network much more responsible. Progress in PONs is but 1 sign that the old battles amongst the cable and telcos individuals are just as active as ever.

Infonetics Research this 7 days launched its fourth quarter sector share figures. There is the predicted jockeying amongst the leading gamers. The “perennial chief” is Mitsubishi, and other crucial gamers are Fiberhome, Lucent, Motorola and Tellabs. A lot more importantly, optical network models and optical mild terminals (ONUs and OLTs) – two important factors of a PON network – had been up 38 per cent, which suggests a thriving sector. The report adds that Gigabit and Ethernet PON (GPON and EPON) led the way and that all round PON production was stable. This is good news in a negative economic climate and subsequent a quarter in which the category expired by 24 per cent. The report&#39s other highlights carry equally good news for the category.

PONs are a most important architecture for phone businesses in the United States. The truth is that tiny telcos are actively deploying fiber devices, though most of the general public goes to the large Verizon FiOS and AT & T U-Verse initiatives. This 7 days, those smaller sized businesses had been in the news as Occam Networks introduced a few discounts. The vendor said that two Kentucky cooperatives – Peoples Rural Telephone and Ballard Telephone – are deploying its Broadband Loop Carrier 6322 GPON OLT and ON 2442 GPON Triple Play Gateway optical network terminals. Nex-Tech, a phone corporation in Hayes, Kansas, will incorporate to its Occam products, though the release was not as particular on what the corporation is adding.

The cable operators are heading to PON architectures as very well. Finding to that position is a diverse proposition, nonetheless, since of the business&#39s preexisting hybrid fiber-coax (HFC) architecture. The business&#39s target is to limit the dislocation that would be caused by a large switchover from radio frequency (RF) to optical transmissions. To do this, the business is baking up a set of protocols referred to by the good acronym RFoG (RF over Fiber). The category is commencing to make news. Previous thirty day period, for instance, GPON vendor Zhone Know-how and RFoG vendor Alloptic introduced a strategic arrangement. The pact will help Zhone to boost the quantity of spectrum to cable operators, the story says.

RFOG, PONs and other unique sounding architectures and techniques seriously boil down to 1 easy to understand equation: Both industries are battling to migrate their infrastructures to create much more earnings, but to do so with the the very least feasible expenditure and disruption. Media Ordeals 2 Go, a Motorola web site, stories that Time Warner Cable has issued a request for info on RFoG and that Motorola and Alloptic have a offer in place that will extend Motorola&#39s RFoG line.

It&#39s interesting to get the see of folks close to the systems underneath consideration. That&#39s the case in this piece, which focuses on the feelings of Rouzbeh Yassini, who is informally recognised as “the father of the cable modem.” Yassini, talking at the Cable Next-Gen Broadband Procedures meeting last thirty day period, suggested that the third iteration of the cable business&#39s Details About Cable Services Interface Specification (DOCSIS three.) will help the business&#39s existing hybrid fiber-coax (HFC) architecture for seven or 8 years, according to a the latest Cable Digital Information report. The sticking position, nonetheless, is the business&#39s chronically constrained field-to-headend “upstream” path. Alternatives stated contain RFoG and PON.

The cable and phone businesses have been going at it tooth and nail for decades. It&#39s good for their planning and engineering departments – not to mention suppliers and a stray blogger or two. The specific nature of the technologies, not the contentious dynamic, is the only thing that changes. At instances, it would seem that the business with the weaker technologies is experiencing catastrophe. Now, nonetheless, it seems to be that both of those industries have place more than enough study and wondering into their platforms that they will sustain them easily, no issue what the other facet does.
