摘要光学电路交换（Optical Circuit Switching, OCS）技术代表光网络从传统"连接"功能向智能"交换"功能的战略演进，作为解决传统电交换带宽瓶颈和功耗问题的关键路径，正成为光厂商竞相布局的新战场。【OCS技术概述：光域直接交换的实现】光路交换机（OCS）：不同于传统交换机，直接光路交换，无需做光电转换。OCS ...

Circuits as WAN connections battled successfully against packets for years because they guaranteed bandwidth, no matter what. If you bought a T-1 circuit, the service provider nailed up 1.5Mbps from ...

Hybrid relays combine a mechanical switch with a solid-state switch, and they are set up in parallel to control a single load ...

Researchers are working hard around the world to try and improve the speed available for data sharing. Microsoft Research and EPFL recently demonstrated ultrafast optical switching utilizing a ...

This design, based on a Maxim MAX220 RS-232 driver/receiver IC, allows you to increase the number of USARTs (universal synchronous, asynchronous receiver/transmitters) available on a microcontroller.

Coherent Corp. has announced the launch of its 2D Collimator Array, an innovative optical assembly designed for use in optical circuit switches (OCS), which are increasingly vital for advanced data ...

Efficiency is often the main objective when using switching regulators. High efficiency means less power drain on the input source (batteries, etc.) and less heat ...

Many hardware people around these parts will be familiar with devices used as switches, using at least three-terminals to effect this, an input, an output and a gate. Typical devices that spring to ...

Ground start is the primary analog signaling method used between telephone switches such as the central office (CO) and a private branch exchange (PBX). It offers a way to indicate on-hook and ...
