I ran across the following article in Info World, any comments would be appreciated. ATM switch tailored for distance boost Info World, January 25, 1999 (Vol. 21, Issue 4) By Laura Kujubu Fore Systems at the ComNet exposition in Washington this week will announce that its ForeRunner ASX-4000 ATM switch will include wavelength division multiplexing (WDM) technology, for improved long-distance networking. ASX-4000 -- the company's flagship switch designed for large enterprises and service provider networks -- has been integrated with OC48c WDM interfaces. This increases the switch's optical capacity to 10Gbps. The combination of ATM and WDM increases the transmission speeds for long-distance networking, Fore Systems officials said. "We're combining WDM transmission and ATM switching," said Mike Lisanti, product manager for ASX-4000 at Fore Systems. "We're able to get 10Gbps over a single fiber -- that's the equivalent of OC192 capacity." Lisanti added that the integration of WDM also allows for greater distances between networks. Because the WDM port cards use 1,550 nanometer wavelengths, the cards can directly interconnect networks at distances as far as 40.3 miles. And this can be extended to more than 62 miles with off-the-shelf line amplifiers, he said. "This all leads to cost savings ... it saves the cost of installing new fiber," Lisanti said. Analysts said the integration of WDM into ATM switches presents an attractive solution. Erica Henkel, an analyst at Frost & Sullivan, in Mountain View, Calif., called the combination "an interesting development in the transmission industry." He added that users will now be able to get more bandwidth from their ATM networks, as well as better cost-efficiencies. Indeed, although WDM-capable products may be equally appealing for service providers and large enterprises, analysts also noted the latter is playing the waiting game. "Enterprises are going to wait until prices come down," Henkel said. "WDM is not even widely deployed at the RBOC [regional Bell operating company] level yet." The WDM-capable ASX-4000 switch products will be available in March. Pricing has not yet been set. Fore Systems Inc., in Pittsburgh, can be reached at www.fore.com.
