The design of a fiber-optic local area network (LAN) demonstration system is described. A complete LAN system would consist of an array of 16 personal computers (PC's), where each PC has a network interface card (NIC) with a parallel fiber-optic datalink to a centralized optoelectronic switch core. The centralized core switches the data generated by 16 NIC's, up to 128 Gbit/s of bandwidth. The demonstrator is designed to scale to terabits of bandwidth by use of an emerging optoelectronic technology, i.e., integrated complementary metal-oxide semiconductor (CMOS) substrates with vertical-cavity surface-emitting laser (VCSEL) and photodetector optical input and output. A subset of the complete system was constructed and is operational. A prototype NIC card, with Motorola Optobus VCSEL transceivers for the optical datalinks, was constructed and is described. A prototype high-speed bipolar switch core, with statically configurable electrical positive-emitter coupled-logic 16 x 16 crossbar switches, CMOS field-programmable gate arrays, and Motorola Optobus transceivers, was constructed and is described. We successfully demonstrated the transmission of high-speed packetized data from one NIC card, through 10 m of parallel fiber ribbon and the centralized switch core, and back to the NIC. We summarize our experiences on the design and testing of our first demonstration system and our development toward a terabit switch core.
本文描述了一种光纤局域网（LAN）演示系统的设计。一个完整的局域网系统将由16台个人计算机（PC）组成，每台PC都有一个网络接口卡（NIC），通过并行光纤数据链路连接到一个集中式光电交换核心。该集中式核心可交换由16个NIC生成的数据，带宽高达128 Gbit/s。该演示器旨在通过使用一种新兴的光电技术，即集成互补金属氧化物半导体（CMOS）衬底与垂直腔面发射激光器（VCSEL）以及光探测器光输入和输出，扩展到太比特级带宽。构建并运行了完整系统的一个子集。构建并描述了一种用于光数据链路的带有摩托罗拉Optobus VCSEL收发器的原型NIC卡。构建并描述了一种原型高速双极开关核心，它具有静态可配置的电正发射极耦合逻辑16×16交叉开关、CMOS现场可编程门阵列以及摩托罗拉Optobus收发器。我们成功演示了高速分组数据从一张NIC卡通过10米并行光纤带和集中式交换核心传输并返回NIC的过程。我们总结了在第一个演示系统的设计和测试以及向太比特开关核心发展方面的经验。
