Possibilities for Passive Optical LAN
Discerning Analytics LLC, June 2010, Pages: 17
For years, optical and data products have served separate markets with separate equipment. The data center and corporate network have been the home to hundreds of thou sands of Ethernet switches, while most optical products have stayed out in the telco core. However, new advances promise to alter this market, bringing optical products closer to desktop workers, and forcing telecom providers to reconsider their data services.
By eliminating the need for workgroup switches, Passive Optical LANs (POL) offer a business justification for fiber optics that differs from 2000-era promises of cutting operational costs. They offer enterprises a large potential savings in cabling costs, and are a significant threat to the existing Transparent LAN market, particularly among the medical and educational campuses that have purchased Transparent LAN services from major telcos. Already aware of this threat, Verizon recently launched a Passive Optical LAN service. While existing Passive Optical Networks have targeted residential applications, many business-serving CLECs now have to give PON technology a second look, as it poses a new threat to the Ethernet LAN offerings they have been offering for nearly 10 years.
Equipment vendors will also need to consider how POL will re-align competitve leaders in data networking. Unlike many other new protocols, POL is being developed by large, established vendors, not startups. It will be much harder to ignore as a result. Additionally, component and structured cabling vendors will need to look more closely at the applications where POL makes sense economically.
In addition to competitive implications across the networking supply chain, this report provides detailed business cases based on different deployment scenarios. It looks carefully at where the economics for POL look very strong, and at the components driving cost differences with Switched Ethernet.
