The is an increasing demand for Synchronous Optical Network (SONET) network equipment among telecommunication carriers. SONET is a transport technology that uses the dual ring of fiber-optic cables and redundant central office (CO) equipment to connect a customer site to a lone or multiple COs. Proper planning and risk mitigation strategies are necessary in SONET technology implementation. An important aspect in the SONET selection and implementation is the relationship with the carrier. The carrier must have a thorough knowledge in the design of the SONET environment., To make sure a SONET deployment delivers on the promise of reliability, keep an eye on your carrier. In recent years, high system uptime requirements, poor carrier service performance and [...]

Optical fiber architecture was designed considering four technologies which focused on wavelength service to achieve accelerated deployment of an all-optical network. Arrayed waveguide grating provides accurate multiplexing and demultiplexing of optical signals. Acousto-optic tunable filter produces acoustic waves for wavelength selection. Multi-wavelength substrate fabrication enables matching of wavelength grids for multiplexing systems. Wavelength translation enables optical switching technology for payload transparency., How four technologies will accelerate deployment of optical network architectures. Significant advances in optical fiber components are accelerating carder interest in design and deployment requirements for the all-optical network. Initial [...]

Pakistan, a country of 118 million with 1.25 percent telephone penetration, is spending about $200 million in 1993-1994 on imported telecommunications equipment. And, this does not include private investments in [...]

Pacific Bell's ambitious plant to rewire its local loop with fiber/coax is fueled in part by its belief that the new network will actually be much cheaper to operate than […]

Fiber optics technology has pervaded the whole of the UK's communications network save for the local loop. Cost was the main issue holding fibre optic technology back from the home. British Telecommunications PLC launched the two-year Local Loop Optical Fibre Trial in 1990 to discover whether optical fibre is technically feasible and cost effective for direct provision to residential and business premises. The LLOFT will also provide practical operational experience for participants, compare different fiber networks and implementation techniques and improve cost projections.

Whenever I write a column about municipal fiber-to-the-premises networks, it's always followed by a surge of responses from readers, most of whom disagree with me. What was new last week, [...]
