The myths and realities of reduced bend radius fiber By Pat Thompson and Mike Hoppe, ADC -- Although reduced bend radius fibers represent a major breakthrough in attenuation prevention, service providers and network architects who assume they are indestructible can put network performance at risk.
GPON vs. HFC: The next technology battle By Alan Marks, Alcatel-Lucent -- Telephone companies are aggressively marketing the superiority of their GPON-based FTTP networks versus the cable multiple-system operators' HFC/DOCSIS networks. But just how much of an advantage does GPON technology provide?
Expanding the bandwidth pipe: Subwave technologies By Brian Pratt, Meriton Networks -- Rather than dedicate a wavelength to a single service, subwavelength grooming techniques now enable carriers to pack wavelengths with as much traffic as possible for more efficient utilization.
Fiber to the premises: Eight lessons learned By David Russell, Calix -- More than 1,000 communities in North America currently enjoy FTTP deployments as their service infrastructure. Although this number represents only a small fraction of the homes in the U.S. -- around 1% -- clear lessons have emerged as to which critical factors lead to the success or failure of these deployments.
Increasing fiber in cable's diet By Jim Farmer, Wave7 Optics -- FTTH is usually associated with telco networks. But greenfield FTTH deployments can complement an MSO's existing hybrid fiber/coax infrastructure as well.
OAM: Going beyond the standards to enable innovative Carrier Ethernet services By Umesh Kukreja, Atrica Inc. -- While Carrier Ethernet OAM has come a long way, some functionality gaps still exist, and these gaps must be addressed to enable true, carrier-class OAM for Carrier Ethernet services.
FTTH gives homeowners a raise By David Meis, Corning Cable Systems -- Don't overlook the "FTTH factor" when pricing the fiber-connected home.
Rolling out business Ethernet By Fred Ellefson, ADVA Optical Networking -- Ethernet demarcation, service ubiquity, and end-to-end testing, monitoring, and verification of SLAs are key considerations for the cable MSO seeking to offer an intelligent Ethernet service.
Traffic engineering for Ethernet: PBT vs. T-MPLS By Peter Lunk, Extreme Networks -- Both PBT and T-MPLS provide the latest evolutionary step in Layer 2 networks by providing the traffic engineering capabilities necessary to achieve the determinism and resiliency needed for today's advanced real-time services.
PODCAST: Luxtera talks CMOS Photonics In an interview with Editorial Director Stephen Hardy, Luxtera's VP of Marketing Marek Tlalka explains why the monolithic integration of germanium-based photodetectors with CMOS electronics is a big deal.
