Allayer Announces First Fast Ethernet Twisted-pair to Fiber Converter IC.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--June 7, 1999-- -0- -- Replaces Five Devices to Convert Twisted-pair to Fiber -- Lowers Cost of Fiber Optic Connections to PCs and Workstations -- Supports Redundant Fiber Links for Fault-Tolerant Networks -0- Allayer Technologies Corp. announces a single-chip transceiver that converts twisted-pair Fast Ethernet (100Base-TX) signals into fiber-optic Fast Ethernet (100Base-FX). The AL210 supports redundant fiber links for fault-tolerant connections and conforms to the IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.3 Ethernet standard. It replaces five chips and enables the design of low-cost converter modules that economically connect PCs and workstations to fiber optic networks. Modules are used between switches and routers to convert twisted-pair links into longer (by twenty times) and more reliable fiber connections or to design new network interface cards (NICs) that support both fiber-optic and twisted pair Fast Ethernet links. According to David Wong, Marketing Director, "There are millions of networked personal computers and workstations using twisted pair Fast Ethernet connections that can be upgraded to fiber optics fiber optics, transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber ." Key elements include a channel that receives twisted pair Fast Ethernet signals and performs clock recovery, a descrambler de·scram·bler n. An electronic device that decodes a scrambled transmission into a signal that is intelligible to the receiving apparatus. descrambler that forwards data to the LED driver, a quantizer that decodes fiber waveforms, a clock recovery circuit, and an elastic store that formats data for transmission over the Fast Ethernet transmitter. The AL210 provides fault tolerant features that improve network reliability and supports both 850 nm and 1300 nm fiber modules. The AL210 is in production and is priced at $11.50 in a 48-pin PQFP (Plastic Quad Flat Package) Refers to many varieties of QFP chip packages, which are molded in plastic. See QFP. (Plastic Quad Flat Pak) in quantities of 1,000. Company Background Allayer produces advanced ICs that increase bandwidth in Internet networks. Allayer ICs make switches smarter and links faster. The corporate name -- pronounced "All-layer" -- represents the intention to provide silicon solutions for all layers of the OSI (1) (Open System Interconnection) An ISO standard for worldwide communications that defines a framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, proceeding to the network model. Founded in 1997, Allayer uses a Modular Systems Standard Product or MSSP (MultiService Switching Platform) A high-end Cisco router that supports high-speed optical connections in the core of the network. See MSPP and MSTP. approach to design the highest performance and most scalable ICs for Ethernet LAN switching and fiber optics. They are used by systems OEMs to create network equipment for the edge network and the enterprise network backbone. Note to Editors: RoX(TM) is a trademark of Allayer Technologies Corp. |
