Upcoming Webcasts

Troubleshooting Fiber Optic Links

Date 01/21/2015 Overview

Troubleshooting fiber-optic systems should be performed in logical steps. This session will show you a logical sequence to follow in order to effectively locate and resolve problems in both proactive and reactive restorations, including key elements and equipment. The content shows the common OTDR signatures that indicate breaks or mechanical stresses, which help to quickly determine the location of a fault. Examples will be given for initial acceptance testing, span testing, splice transit, and receive optical power levels, along with a discussion of the role that proper documentation plays in any successful maintenance and restoration plan.


Understanding Multimode Fiber Bandwidth

Date 11/19/2014 Overview

Due to the low cost of VCSEL light sources, the integration and use of multimode fibers for the transport of data, voice, audio, and video signals will continue to see tremendous growth in high-quality systems. This webinar, presented by The Light Brigade, focuses on the bandwidth requirements of various signal formats and provides an understanding of the fiber’s capabilities and limitations.


Trends in Silicon Photonics

Date 11/12/2014 Overview

Now that much of the breathless hype surrounding silicon photonics has calmed down, what can we realistically expect from the technology? Lightwave Editorial Director Stephen Hardy will discuss the promised benefits of this wafer-level integration strategy and review how companies expect to use it to support high speed transmission in both data center networks and coherent-enabled carrier networks.


Active Optic Cable Test Solutions: Testing AOC/DAC QSFP+ cables up to 100Gb/s

Date 11/06/2014 Overview

The major challenge by far is generating the correct signal conditions defined by the IBTA specification.  Generating high quality test signals is one factor in the total solution.  The other is being able to manipulate and control aspects of these test signals as defined by the specification to produce the required stressed signal conditions.  Anritsu delivers this level of quality and adjustment in the MP1800A Signal Quality Analyzer test platform, making the ATD calibration process a less daunting task.


Verifying PAM4 Performance in 28G & 56G Designs

Date 11/04/2014 Overview

With next-generation CEI-56G Designs being considered, it’s time to understand the performance capabilities and testing approaches for Phase Amplitude Modulated signaling versus traditional NRZ-based architectures. This informative Lightwave webinar will provide participants with a review of 28G and the emerging 56G Standards landscape, straight from the OIF and IEEE organizations. Tektronix will discuss test challenges for PAM-4 including monitoring of signal nonlinearities, and how to setup a testing laboratory for verification of effective BER. The webinar will conclude with a look to the future of OIF-CEI-56G and IEEE400G requirements for test followed by a live Q&A session.


Establishing a Fiber Optic Maintenance Program 

Date 10/29/2014 Overview

Establishing an effective maintenance program for your fiber optic system(s) involves periodic reviews of both the transmission equipment and the fiber plant. This session, presented by The Light Brigade, takes a look at techniques that can be used to test live and dark fibers for potential problems before an emergency restoration is required.  The content also discusses documentation requirements, and makes suggestions and recommendations for system equipment alongside with baseline equipment requirements.


Further and Faster: The Importance of Low Loss for High Capacity Backbone Networks

Date 10/29/2014 Overview

Whether an operator is deploying fiber in new routes or is looking to upgrade the current network to overcome the operational complexity of the existing legacy plant, the challenges inherent to each can be addressed with advanced optical fiber cables and cutting-edge installation methods. In this webinar presented by Corning Optical Fiber, we review the challenges faced by operators in both greenfield and brownfield long-haul deployments and explain how low attenuation fibers can deliver value by minimizing CapEx and OpEx costs and allowing upgrades to higher capacities without compromising the network design.

ECOC 2014 Wrap-up

Live on 10/08/2014 Overview

ECOC 2014 was a hotbed of technology activity, both within the conference discussions and on the exhibit hall floor. Editorial Director Stephen Hardy offers his assessment of the most important themes and announcements. If you didn't have a chance to attend, here's your opportunity to catch up. If you did, compare your impressions with Stephen and become part of the discussion.

Lightwave Live: Maximizing Reach and Efficiency in Enterprise/Data Center Networks

Live on 10/01/2014 Overview

In this edition of our Lightwave Live series, Lightwave Editorial Director Stephen Hardy uses a pair of articles from the September/October 2014 issue of Lightwave to discuss how enterprise and data center network managers can maximize the reach of their fiber-optic networks. He'll also discuss strategies for using optical cables to help power equipment attached to the network, including the use of Power over Ethernet.

This presentation sponsored by AFL, JDSU, and JGR Optics.


Accurate OTDR Measurements in the Outside Plant

Live on 09/24/2014 Overview

The optical time-domain reflectometer (OTDR) is used to perform distance, attenuation, and reflectance measurements.  However, most OTDR users do not know how to properly calibrate their OTDR to perform accurate distance measurements.  This session, presented by The Light Brigade, will explain the causes of inaccurate distance measurements as well as how to correctly adjust the instrument, including how to specify these processes when working with contractors and developing "as-built" documents. Once these procedures are in place, these practices can be used to identify faults with greater accuracy during emergency restorations.
