AstroTerra Launches TerraLink 3000, a High-Performance, License-Free Fixed Wireless Communication Solution.
Business Wire, May 11, 1999 p0525
Full Text SAN DIEGO--(BUSINESS WIRE)--May 11, 1999--
AstroTerra Corp. today introduced the TerraLink(TM) 3000 as the newest offering in its second generation of laser data communication solutions.
The TerraLink 3000 incorporates the same ground-breaking technology used in AstroTerra's satellite-to-ground laser communication system to provide high-performance wireless optical data links between buildings in local area and metropolitan area networks.
Designed with AstroTerra's patented multiple transmit aperture technology, the TerraLink 3000 uses three parallel lasers to insure optimal performance in adverse atmospheric conditions. The TerraLink 3000 can be configured for user-specified data rates of 10 to 155 Mbps. Since the TerraLink 3000 systems are protocol-independent, they can easily be upgraded over time as the user's network environment changes.
"AstroTerra has been working with its strategic partners in a number of different vertical markets to provide a range of free-space laser communication products that can fulfill a variety of networking needs," said Sales and Marketing Director, Steve Barrera. "The TerraLink 3000 was inspired by the recent surge of interest in fixed wireless applications for medium range, high data rate customers. A number of clients need to extend their fiber-based networks to include new buildings and temporary sites. The TerraLink 3000 provides network professionals with an intuitive way to complement their existing physical-layer solutions. Integrating network devices via a simple line-of-sight link, the TerraLinks allow quick backbone expansions without the need for trenching permits or FCC licenses. Compared to traditional leased-line options, the benefits of incorporating these fixed wireless solutions can be seen in both the immediate increase in data throughput and the long-term cost savings."
"In addition to being used for high speed enterprise data networks, laser communication products such as the TerraLink 3000 will find increasing applications in last mile telecommunications service at data rates of OC-3, OC-12 and higher," added Eric Korevaar, AstroTerra president. "Laser communication systems can be deployed rapidly without licenses in locations where fiber connections are impractical and costly, or take too long to install. Laser systems like the TerraLink 3000 can also be used in conjunction with lower data rate microwave links to provide extremely high availability."

Bell Labs pushes gigabit wireless link as a way to boost throughput fourfold. (Company Business and Marketing)
Government Computer News, Feb 8, 1999 v18 i3 p42(1)
Author JACKSON, WILLIAM
Full Text High-powered, fiber-optic amplifiers can transmit up to 2.5 Gbps over distances as far as 1.5 miles without wires.
That is a fourfold throughput increase over current commercial wireless products, which are limited to 622 Mbps and short wavelengths.
The new amplifiers boost power output tenfold, so that the longer wavelengths of fiber-optic transmissions can also work for point-to-point wireless, said Jim Auborn, head of communications technology for Bell Labs, the R&D arm of Lucent Technologies Inc. of Murray Hill, N.J.
"We can blast through much more power, Auborn said. "That means we can overcome weather conditions better, we can go farther and most importantly, we can transmit more data."
Auborn said the transmission rate could in theory reach dozens of gigabits per second, but it will take a couple of years for government applications to appear.
"I think it's going to be government-friendly" for Defense Department and NASA communications satellites, he said. On the ground, the military could use gigabit wireless for rapid deployment of fast data links, he said.
Wireless optical links now use laser-generated light in the 800-nanometer range at 100 milliwatrs of power or less, Auborn said. The new gigabit technology works in the 1.55-micrometer range, and its amplifiers generate up to 10 watts at the longer wavelengths.
Bell Labs' experimental transmissions used laser equipment from AstroTerra Corp. of San Diego. The signals went across a 1.5mile gap from a transmitting telescope to a receiving telescope, which focused them onto fiber by coupling optics.
"We don't see it as a replacement for fiber," Auborn said. But gigabit wireless could supplant other optical wireless links as well as radio and microwave in campus and urban environments or in military situations where it would be impractical to install temporary networks.
Because gigabit wireless uses the same wavelengths as fiber, it could take advantage of fiber-optic techniques such as wavelength division multiplexing to increase capacity. But it has the same drawbacks as other wireless links, Auborn said: It works only on line of sight and is affected by snow, fog and rain.
At distances of a few hundred yards, availability runs about 99 percent. Over distances of a mile or more, that drops into the 90 percent range. "It's not 100 percent available as fiber systems are," Auborn said.
Hovering around
For satellites, which orbit above the weather, the high-powered optical links would be an improvement over current radio bands, which are getting crowded, Auborn said.
"Optical communications are completely unregulated," he said, and optical links are point-to-point, not broadcast. "That's a big advantage because you won't overcrowd the frequency spectrum."
Lucent unveiled first single-laser optical transmission commercial system that can deliver 40 Gbps of capacity.
Communications Daily, March 10, 1999 v19 i46 pNA
Full Text Lucent unveiled first single-laser optical transmission commercial system that can deliver 40 Gbps of capacity. WaveStar 40G Express System, which uses one laser over single wavelength on fiber cable, is 4 times faster than previous single-laser systems with capacities of 10 Gbps, Lucent said. MCI WorldCom (MCIW) is first carrier testing new system and recently hosted lab system trials in Richardson, Tex., network technology laboratories, Lucent said. Lucent plans to deliver system to MCIW for commercial testing by 4th quarter. It said system, developed by Bell Labs, lets communications providers reduce central office space requirements up to 75% by providing 40 Gbps of capacity in single equipment bay instead of 4. Lucent said it plans to use technology in multiwavelength applications to provide capacity of 1 Tbps on single strand. System will be commercially available by next March.
