Title -- “Metro Networks with AllWave Fiber”; against a background of white clouds in a blue sky

Building metro networks ... with high-capacity AllWave fiber from Lucent Technologies.

Camera zooms through clouds and we see a busy city from the sky; as the narration progresses, we get closer to the buildings.

There’s no application more demanding then a metropolitan area network, or “MAN.” The simple reason? The greater density of users in highly populated areas.

Map of United States

How much denser is the user base in metro areas than the U.S. average? The entire United States has a population of around 260 million in an area of almost 4 million square miles.

Green dots appear on the USA map symbolizing a moderate density of users in the network

That’s a population density of around 65 people per square mile.

X-ray of the city shown earlier -- outlines of the buildings are in green

Urban networks serve many more users. For instance, Manhattan, one of the largest cities, has over 7 million people in a 309 square mile area.

Green terminals appear on the metro LAN schematic indicating a high density of users

That’s a population density of over 23,000 people per square mile -- more than 300 times the national average!

Green dots representing traffic starts to flow between the terminals in the metro LAN

The metro network serving a city like New York obviously handles much more traffic than a rural or suburban network -- taxing ordinary fiber to its limit.



Photo or illustration of fiber optic; blue water molecules begin to bound through it as the narrator talks.

Lucent Technologies solves that problem -- with AllWave -- the first high-capacity fiberoptic specifically designed for metro and other high-density applications.

Animation showing water molecules flowing from left to right. As the narrator speaks, a filter comes down to divide the screen vertically. Once it is down, the water molecules are stopped at the barrier. The right side quickly empties of water molecules and becomes blank.

We’ve developed a proprietary filtering technology that removes moisture from the fiber optic during manufacturing.

Ordinary fiber optics contain residual moisture ...

Half the pipe lights up and begins carrying light rays; half remains dark.

...which limits the amount of bandwidth available for traffic.

All of the pipe lights up and begins carrying light rays.

By eliminating water molecules in the glass fiber, AllWave provides 100 nanometers more bandwidth than conventional single-mode fiber.

The light rays each become a different color to symbolize multiple optical paths. Superimpose over this the chart (attentuation vs. wavelength) from AllWave brochure).

As a result, AllWave has 120 or more channels available for metro networks and other wavelength-intensive applications fiber....

The fiber branches out into multiple fibers, with different color paths splitting into the individual fibers.

Giving the network provider the ability to provision a broad range of customized services ...

The camera pulls back so we see an x-ray of the network within part of the city, with different colored fibers going to individual buildings and terminals.

... to a broad range of subscribers.

Piles of cash growing and growing. Superimpose the following bullets over the illustration of money:

The end result? More applications on your fiber reduce the cost per bit per kilometer --

·        Lowest cost per bit per kilometer

·        More usable spectrum

·        Greater ROI

-- maximizing network efficiency, enabling new revenue opportunities, and generating a quicker return on your metro network investment.

Go back to chart of attentuation vs. Wavelength from AllWave brochure. Illuminate the portion of the chart representing the 1,350 to 1,450 nm region  and then dim again as the words “1,350 to 1,450 nanometer wavelength” are spoken.

AllWave makes the 1,350 to 1,450 nanometer wavelength, which is typically “dark” in conventional fibers, available for transmission -- which increases usable wavelength in the fiber by 50 percent, with lower attentuation.

Go back to illustration of a busy city (cars and buildings). Superimpose bullets as follows:

That makes AllWave the only commercially available fiber that allows 3 different signal formats to be simultaneously transmitted over a single fiber:

·        1,530 - 1,625 nm -- long haul


AllWave has excellent dispersion performance in the C and L band, allowing  maximum DWDM wavelength usage in metro applications.


·        1,530 - 1,625 nm -- long haul

·        1,310 nm -- SONET and analog


Metro traffic can be carried via SONET and analog in the 1,310 nanometer band.

·        1,530 - 1,625 nm -- long haul

·        1,310 nm -- SONET and analog

·        1,400 nm -- Wide Wavelength Division Multiplexing (WWDM)


And with a third band at 1,400 nanometers for Wide Wavelength Division Multiplexing, a single AllWave network can offer Internet, video, and voice services over the same fiber.

By reducing the amount of fiber required for the metro network, AllWave helps...

The three fibers morph into a single fiber serving all three applications

....simplify administration and maintenance while reducing operating costs.

Different bands of wavelength within the single fiber light up in sequence to symbolize the network operator choosing different bandwidths for various applications.

And, the network operator can choose the most economical band in which to transmit information, to increase profit margins on each service offered.

Proprietary filtering to remove water from the fiber also results in other operational advantages for networks using AllWave fiber:

·        Longer distances


Longer distances without regeneration, amplification, or dispersion....


·        Longer distances

·        High bit rates

Transmission rates up to ten gigabits per second, with significantly more capacity per fiber....

·        Longer distances

·        High bit rates

·        Flexible system configuration

Flexible configuration of networks, with multiple services on each fiber.

Metro networks are the toughest in the world -- dense populations, heavy traffic, and enormous diversity of services.
