The world's telcos are discovering - some to their delight, others to extreme discomfiture - that while the Internet and the Internet protocol (IP) are transforming telecomms from above, new […]

What's that, you ask? A new technology that's opening vast realms of capacity in the fibers that carry phone and Internet traffic all over the world. None too soon, either. […]

Satellites have long been used to carry voice, data and fax traffic across oceans and within individual countries. Previously, such transmissions were limited to high-traffic applications, as individual routing technology […]

Greg Raleigh didn't do much to earn his way into this year's circle of top innovators. He merely turned the fundamentals of radio science on their heads. In 1996, the […]

SAN FRANCISCO In telecommunications, the long day of the electron has reached its twilight EVEN non-geeks have now heard of Moore's Law, the main ordinance of the electronic realm. Gordon [...]

By Bill Vislosky As optical technology advances, carriers are jumping to realize its potential to generate revenue and reduce costs. They want to deploy the most advanced optical technology they […]

Rethinking the Private Voice Network in the Age of the Private T1 Backbone More money is probably spent today on advancing high-speed multiplexing technology than at any other time since […]

Cable Multiplexing: Part I Over the years, the RS-232C interface standard has been revised several times. In satisfying its need to maintain compatibility with earlier versions, however, RS-232C has several […]

Fast Packet Switching: A Tutorial There is a great deal of confusion regarding fast packet switching. As the term 'packet' is used, many assume that fast packet switching is simply […]

Regional Bell Operating Companies are concerned about the costs of adding dense wavelength division multiplexing (DWDM) into their operations support systems. On the other hand, Bell Atlantic, believes that DWDM is the next step in the evolution of transport and switching networks. It is already using DWDM technology on point-to-point systems to increase capacity. Mike Daigle, Bell Atlantic's director for transport circuits, insists that DWDM systems do not cost more than Sonet add/drop multiplexers since DWDM is also based on signal speed and circuit type information., Primary and secondary long-haul carriers have adopted dense wavelength division multiplexing (DWDM) across the board, and regional Bell operating companies (RBOCs) are following suit. Will they find that connecting DWDM [...]

NTL Demonstrates Multichannel System London - NTL, a British supplier of transmission services, demonstrated here two weeks ago a multichannel TV transmission system that's not distributed over cable or satellite, [...]

Cablevision Systems Corp. is exploring the use of multiple wavelengths over a single fiber as a means to quick, low-cost expansion of the hybrid fiber/coax platforms it is installing throughout [...]

Monolithic video multiplexers direct 300-MHz data in 300 ns Designing suitable circuitry for routing and switching wideband analog and digital signals challenges the system engineer who must consider such factors […]
