OM4 Optical Fiber Cabling Overview

As increased bandwidth requirements are called out in new installations, particularly 40 and 100 Gb/s standards, transmission distances over fiber optic cables contained in existing infrastructure may become increasingly limited. Increasingly, these higher bandwidth system requirements have dictated a need to transition from cost-effective multi-mode systems to more costly single-mode systems. Until OM4 was formally ...

In 2010, the IEEE ratified the 802.3ba standard for 40/100GbE. Similar to how transportation highways are scaled to support increased traffic with multiple lanes, the 40GbE standards use parallel optics, or multiple lanes of fiber transmitting at the same speed. This cost effective 40GbE solutions are a key enabler for delivering support for higher bandwidth ...

Introduction to Serial and Parallel Communications

There are two ways of transmitting a byte between two digital devices. We can either use PARALLEL optics to transmit the byte or we can use SERIAL optics to transmit the byte. This article will cover the introduction, difference, and application of the two communication modes. Introduction to Serial and Parallel Communication Serial communication sends ...
