A Focus on the Critical Optical Parameter Attenuation

1 Comment

Our first article in this series highlighted some bandwidth demand drivers and introductory standards information. This article will focus on critical optical parameters starting with optical attenuation. Additional articles in this series focus on other optical parameters, including chromatic and polarization mode dispersion, splice loss, and an introduction to non-linear effects. > Download the Full […]

Placing Fiber Optic Cable in Underground Plant

Leave a Comment

Placing Fiber Optic Cable in Underground Plant 1. Overview This document covers cable placing in conduit, innerduct, handholes, and manhole structures. The innerduct may be direct buried or placed in larger diameter conduits. In some applications, the innerduct may be lashed to an aerial strand. This document covers conventional cable placing techniques that are used […]



Advances in Laser Lithotripsy for Kidney Stones

Understanding Optical Fiber Specifications This article in our technical series will focus on single-mode optical fiber geometries. If you subscribed to our Light Post Emails you know we previously covered bandwidth demand drivers and introductory standards as well as fiber optic dispersion.In this article we’ll work our way through a typical fiber specification, highlighting the […]


What is Distributed Acoustic Sensing (DAS)?

Leave a Comment

Distributed Acoustic Sensing (DAS) is a technology that enables continuous, real-time measurements along the entire length of a fiber optic cable.  Unlike traditional sensors that rely on discrete sensors measuring at pre-determined points, distributed sensing utilizes the optical fibre. The optical fiber is the sensing element. AcoustiSens® Wideband Single-Mode Optical Fiber, the newest addition to […]

A Hollow-Core Fiber Cable for Low Latency Transmission – when microseconds count

Leave a Comment

AccuCore HCF™ Optical Fiber Cable is the world’s first terrestrial hollow-core fiber (HCF) cable solution. Light travels about 50% faster in a hollow core optical fiber compared to the solid silica core of conventional fiber. Consequently, light transmitted in a hollow-core fiber arrives 1.54 microseconds faster for each kilometer traveled compared with conventional optical fiber. […]

The OFS Fiber Connection in The U.S. Virgin Islands

Leave a Comment

The co-inventor of optical fiber, Dr. Peter Schultz, is a resident of the Virgin Islands. He was instrumental in convincing the local authorities back in the early 2000’s that the islands needed high-speed connectivity afforded by optical fiber. He assisted in the successful lobbying of federal and local governments to provide funding for the project […]

Fiber Optic Dispersion and other Non-Linear Effects

Leave a Comment

This article focuses on the parameters that affect available bandwidth in optical fibers, and the dispersion mechanisms of various fiber types and non-linear effects.  Dispersion describes the process of how an input signal broadens out as it travels down the fiber. There are several types of dispersions that we will cover. We’ll also take a […]
