SilkRoad Completes Successful Field Test Of SRSC Technology; Achieves Simultaneous Bi-Directional 400-Megabyte File Transfer Over 47 Kilometers On A Single Wavelength.SAN DIEGO--(BUSINESS WIRE)--Sept. 1, 1999-- SilkRoad Inc., an innovative optical networking technology company, today announced the successful results of a simultaneous bi-directional, single-wavelength field test of its SilkRoad Refractive Synchronization Communication (SRSC (SilkRoad Refractive Synchronization Communication) See SilkRoad. (TM)) technology. Using its Emissary(TM) optical transceivers as the end-to-end transport interfaces between two high-performance SGI (SGI, Sunnyvale, CA, www.sgi.com) A manufacturer of workstations and servers, founded in 1982 by Jim Clark. The company was founded as Silicon Graphics, Inc., but changed to its acronym in 1999. (TM) Origin(TM) 2000 servers, a point-to-point connection was established between San Diego State University San Diego State University (SDSU), founded in 1897 as San Diego Normal School, is the largest and oldest higher education facility in the greater San Diego area (generally the City and County of San Diego), and is part of the California State University system. (SDSU SDSU San Diego State University SDSU South Dakota State University SDSU Standard Distribution Switching Unit SDSU Smds Dsu ) and Chula Vista, Calif., a distance of 47km. The test was run on a private in-the-ground fiber network. Two 400-Megabyte (MB) data files were simultaneously transferred bi-directionally (800 Megabytes on the same signal path) over a single wavelength on a single fiber in 11.4 seconds. The SRSC(TM) network capacity utilized was over 71 Megabytes per second (unit) megabytes per second - (MBps, MB/s) Millions of bytes per second. A unit of data rate. 1 MB/s = 1,000,000 bytes per second (not 1,048,576). . In comparative terms, industry-standard remote WAN connections at T-1 or Asynchronous Refers to events that are not synchronized, or coordinated, in time. The following are considered asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end.

(communications, protocol) Digital Subscriber Line - (DSL, or Digital Subscriber Loop, xDSL - see below) A family of digital telecommunications protocols designed to allow high speed data communication over the existing copper telephone lines between end-users and (ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line ) speeds would have taken over 66 minutes to transmit both files (a minimum of 33 minutes for each file). "This test showcases some of the unique benefits of SilkRoad's single-wavelength SRSC(TM) technology. Our ability to send information faster and farther down a network, bi-directionally, simultaneously, all on a single wavelength means greater network efficiency and cost savings over current technologies such as Gigabit Ethernet and Fiber Channel," said Kevin Doria, SilkRoad president and chief executive officer. "These capabilities, along with SRSC(TM)'s ability to send a mix of voice, video and data on a single wavelength, show the potential for SRSC(TM) to increase bandwidth and provide solutions for the converging communications market." Emissary transceivers are designed for enterprise-level, multi-media communications over fiber-optic point-to-point and ring networks. Emissary can process combinations of optical, digital, and video signals simultaneously, making it an ideal solution for large, mission-critical, mixed-technology data transmissions. The ability to transfer multiple, mixed-technology messages simultaneously makes Emissary transceivers ideal for distributed supercomputing, large file transfers, real-time video conferencing, interactive distance training/learning, telemedicine and health care imaging, multimedia/publishing, railroads and utilities, private networks, and network revitalization. (Editors' note: Please see related 7/21/99 release regarding the introduction of the Emissary optical transceiver, the first commercial application of SRSC(TM).) SilkRoad's Refractive Synchronization Communication (SRSC(TM)) technology, was first introduced during the company's worldwide technology launch on Wall Street in New York City New York City: see New York, city. New York City City (pop., 2000: 8,008,278), southeastern New York, at the mouth of the Hudson River. The largest city in the U.S. on Nov. 3, 1998. SRSC(TM), based on new applications of well-established principles of optical physics, allows a properly modulated single-wavelength laser beam to carry multiple electronic signals in a bi-directional format. As a result, SRSC(TM) based systems provide significant benefits for network accessibility and the transport of high speed, high volume, voice, video and data communications beyond those achieved through conventional multiple-wavelength technologies. The economical pricing of a SRSC(TM)-based system makes true extreme broadband communications available to the converging communications market. Founded in 1996, SilkRoad Inc. is a privately held company privately held company A firm whose shares are held within a relatively small circle of owners and are not traded publicly. headquartered in San Diego, where sales and marketing, research and development, engineering and administration are located. The company's patented SilkRoad Refractive Synchronization Communication (SRSC(TM)) single wavelength technology provides the basis for next-generation communications systems that dramatically increase bandwidth, accessibility to information, scalability and network simplicity. SRSC(TM) technology provides products for telecommunications, CATV (Community Antenna TV) The original name for cable TV. It used a single antenna at the highest location in the community in order to deliver a quality signal to homes in areas with hilly terrain or other interference. and Enterprise markets for long haul, metro, access and local networks. SilkRoad recently received the SUPERQuest Award for the "Most Promising New Technology," in optical networking at SUPERCOMM '99.
