Infinera’s Last Ditch: Infinity and Beyond

May, 2016

With the full realization by industry analysts, some of whom initially drank the Kool-Aid, that the potential for Infinera significantly penetrating the metro optical market will not be a pushover, the supplier’s frantic gambit is to prematurely advance a marketing message to the extreme on the Long Haul (LH) side with its Infinite Capacity Engine (ICE). With the bulk of the LH carrier space continuing to migrate to 100G, its Gen 4 technology supposes the potential for well over an order of magnitude increase in capacity deployment. A reasonable presumption is that in the vast majority of cases, it will take a very long time to reach exhaust at 100-gig with the use of DWDM. (Infinera dodged a question about the relatively low number of wavelengths at that speed during the last quarterly earnings conference.) The company’s arguments about a direct correlation between expectations of...

Submarine Festoons Needed in US

November, 2016

Although undersea festoon networks can be found in many parts of the world, one would be hard-pressed to locate a single case in the States. From the perspectives of lower cost, speedier and simpler deployment, as well as indiscernible environmental impact, they should be a slam dunk. Nevertheless, for many years, the permission that is necessary from the various individual localities (all with different requirements) along with the studies that are demanded on both the west and east coasts of the country have made the otherwise practical usage of festoon applications cost-prohibitive, especially given the relatively short distances of the loops in this kind of an infrastructure. It is just one more example of how governmental bodies along with extremists on the environment get in the way of technological progress. In addressing the relatively small number of influential people in the...

Verizon’s 5G Fronthaul Fiber Sustainability

April, 2019

Proficient, long-time networking engineers and planners comprehend that designing architectures can be really tough, and they realize the main reason Verizon wants to do home-runs from the CO to the cell towers for 5G. A centralized approach reduces the number of active nodes in the field that require power (including backup) and maintenance, which will become part of the total lifetime cost of sustaining the service. In fact, of all of the principal necessities for a small cell, the priciest is power. So, in not introducing a large number of intermediate points, just the expense saved in not having to replace the batteries every several years can be substantial. Another big advantage with placing all of the Baseband Units (BBUs) at the CO is that there is the most efficient use of the bandwidth, as there will be variations on the number of users at each of the towers. Other benefits of...
