Denver-area carrier lights optical network

APRIL 24, 2007 -- foreThought.net, a telecommunications service provider for home and business throughout the Denver metro area, has announced the completion of a wholly owned fiber-optic network.

The network currently links several buildings in downtown Denver, but expansion plans are already in place to complete a redundant fiber ring serving twice the current number of buildings. Not only does the fiber network provide a dramatic increase in capacity, it also will provide access to numerous other telecommunications carrier networks via Gigabit Ethernet technology, according to the carrier.

"As we continue to achieve record sales of our PerfectFone voice and EtherLoop Business Broadband services, we need faster, more reliable connections to the Internet and to other carriers. Our rapid growth in all business segments was the impetus for our decision to build the network," said Jawaid Bazyar, president of foreThought.net. Bazyar continued by commenting, "This network not only addresses our needs today, but will enable us to easily deliver other advanced services in the future -- including video-phone, television, and video-on-demand services."

"By laying and lighting fiber cable we own, we guarantee the type of reliability foreThought.net customers have come to expect," added Jeff Burnett, director of operations. "Another benefit of owning our own fiber is financial. This fiber asset positions us not only to meet any customer bandwidth requirements, but do so without increasing costs."

Bazyar closed by stating, "We are proud to provide both current and prospective customers the most advanced, cost-effective telecommunications services available in Denver and the Front Range."

Optical fiber communication

Optical fiber can be used as a medium for telecommunication and networking because it is flexible and can be bundled as cables. It is especially advantageous for long-distance communications, because light propagates through the fiber with little attenuation compared to electrical cables. This allows long distances to be spanned with few repeaters. Additionally, the light signals propagating in the fiber can be modulated at rates as high as 40 Gb/s, and each fiber can carry many independent channels, each carried by a different wavelength of light. In total, a single fiber-optic cable can carry data at rates as high as 14 Tb/s. Over short distances, such as networking within a building, fiber saves space in cable ducts because a single fiber can carry much more data than a single electrical cable. Fiber is also immune to electrical interference, which prevents cross-talk between signals in different cables and pickup of environmental noise. Because they are non-electrical, fibers can be used in environments where explosive fumes are present, without danger of ignition.

Although fibers can be made out of transparent plastic, glass, or a combination of the two, the fibers used in long-distance telecommunications applications are always glass, because of the lower optical attenuation. Both multi-mode and single-mode fibers are used in communications, with multi-mode fiber used mostly for short distances (up to 500 m), and single-mode fiber used for longer distance links. Because of the tighter tolerances required to couple light into and between single-mode fibers; single-mode transmitters, receivers, amplifiers and other components are generally more expensive than multi-mode components.

Furukawa America to demo new FITEL Splice-on-Connector at OFC/NFOEC 2007

PEACHTREE CITY, Ga., Mar 21, 2007 (BUSINESS WIRE) -- Furukawa America Inc. will demonstrate its new FITEL(R) splice-on connector at OFC/NFOEC 2007 in Anaheim Mar. 27, detailing how it speeds fiber repair, improves FTTx installation times and limits insertion loss.

FITEL's innovative connector termination system consists of factory-polished ferrules with pre-cleaved fiber stubs along with high-strength, snap-on connectors. These critical improvements speed installation time and ensure consistently higher quality terminations in the field and factory. Total insertion loss using this fusion splice termination method measures .30dB or less for single mode fiber and is available in SC and FC connector types.

FITEL's splice-on-connector also enables quick, made-to-length drop cable installations, a field customization that traditionally requires excess and costly preterminated jumpers and splice trays.

"Fiber installers face daily pressure for fast, error-free work," said Jason Greene, Furukawa America's fusion splicer division manager. "Fiber-to-the-home installations and densely populated fiber hubs also present space constraints. The FITEL splice-on-connector successfully addresses these issues and enables simple, fast and consistent terminations."

FITEL's factory-polished ferrules with pre-cleaved fiber stubs are spliced onto the field fiber utilizing FITEL's proprietary ferrule holder and fusion splicer. Either an SC/APC, SC/UPC, FC/APC, or FC/UPC connector is then quickly and easily assembled due to the precision and simplicity of the rugged connector components. FITEL's splice-on-connector system features high quality, GR-326 tested Seikoh Giken connectors, long known for strength, durability and reliability.

Fiber management is also easier with the FITEL splice-on connectors. The connector termination feature on the FITEL S122A clad alignment splicer and FITEL S177A core alignment splicer eliminates the need for splice trays, resulting in easier fiber management, reduced storage requirements and faster installation times.

Furukawa America Inc. (www.FurukawaAmerica.com, www.BuyFITEL.com) supplies FITEL fusion splicers and fiber optic products to the telecommunications, data, and CATV industries throughout the Americas. FITEL's fusion splicers include hand-held, clad and core alignment and mass fusion splicers plus related tools. Furukawa America also supplies FITEL 980nm and 1480nm pump lasers, signal lasers, active and passive optical components and connectors. Its parent company, The Furukawa Electric Co. Ltd. (www.furukawa.co.jp/english), is a $7 billion global leader in the design, manufacture and supply of fiber optic products, electronics components, and other advanced technologies.
