Optical Software Defined Networking

03/30/2015

Software Defined Networking and Network Function Virtualization have great potential to improve the flexibility and responsiveness of networks, decrease operating /capital expenses, and add new, innovative features to many different types of communications networks.  Standard bodies have begun defining a common software interface to optical transport SDN. In the meantime, SDN principles can be extended to the optical arena, but must be done with care to ensure compatibility with emerging standards.

In this white paper, MRV will explain our approach to Optical SDN, the current status of industry standards, and where we believe Optical SDN will add value to customers’ networks, both today and in the future. We will introduce the components of Optical SDN that are designed into MRV’s new generation of optical transport equipment and show how they can allow customers to leverage advanced, software-based architectures, in order to add flexibility and resource optimization to the optical transport.

Characterizing and Verifying Compliance of 100 Gb Ethernet Components and Systems - Application Brief

03/30/2015

Ethernet data bandwidth expansion from 10 Gb/s to 100G (and 1 Tb/s in the future) is a direct result in the rapid growth of capacity in modern data centers. The recent release of a series of Standards supporting 100Gb Ethernet and 32G Fibre Channel enables component and system designers to implement next generation designs utilizing serial links at these speeds. Download the application note to learn new measurement techniques needed to characterize designs and validate compliance to Standards using 25/28 Gb/s line data rates.

Electro-Thermal Actuated MEMS Mirrors for 100G Fiberoptic Switching and Attenuation Components

03/25/2015

Fiber optic switches and variable optical attenuators (VOA) are crucial fundamental functional blocks of optical fiber networks for the telecommunication and data communication industries. Analog and latching types of electro-thermal actuated optical MEMS provide the cores for unique optical switch and variable attenuator products for light path control in communication networks. Many service providers are using the 100G technology roll out as an opportunity to upgrade their optical network infrastructure, leading to a large demand for advanced optical switches and VOAs.  The performance and cost structure of electro-thermal actuated active MEMS mirror/shutter devices make them exceptionally well suited for application in telecom and datacom optical light path switching and attenuation.

OTN - What is it and Why is it Important? Technical level 1 (Basic)

02/26/2015

This white paper provides essential knowledge for engineers working with OTN and wanting to learn more.  The core of most telecom operator networks today is SDH/SONET (Synchronous Digital Hierarchy/Synchronous Optical NETwork), which has become the expected minimum in performance objectives for network operators today and is often described as having “five 9s” (and higher) performance, meaning at least 99.999% up time.
 
Many operators are implementing a Packet-Optical Transport Systems (P-OTS) network supporting integration of Reconfigurable Optical Add/Drop Multiplexer/Wavelength Division Multiplexing (ROADM/WDM) and L2 (Layer 2) switching as well as SDH/SONET.

PON and Blown Fiber: The Optimum Solution for Today's High Gigabit Speed Enterprise Networks

02/02/2015

 As enterprise network managers, challenged like never before, seek to keep up with current and future exponential growth of data and to find the most reliable, efficient, and cost effective means to support 40Gbs/100Gbs, more and more are looking toward the passive optical network (PON) as a viable solution. This analysis addresses the many advantages of PON including the reduction of significant costs, maintenance, and energy concerns, while illustrating exactly how the PON best optimizes the enterprise network. The study also incorporates the advantages of blown fiber technology with the PON.  A case is built to show that these two technologies ,together, provide synergy that can generate even greater cost efficiencies and prepares the enterprise network with a real-time, on-site, immediately scalable, and already futureproofed network to quickly—often in minutes—meet the unforeseeable, but certain, changes characterized by today’s bandwidth hungry information and communications environment.  

Experience the Network as Your Customers Do— Closing the Turn-up Gap

01/01/2015

Experience the Network as Your Customers Do-Closing the Turn-up Gap This white paper highlights the gap between current Ethernet service-activation methods RFC 2544 and
Y.1564 and the end-customer experience. Customer applications ride on top of the TCP layer and its performance is greatly affected when moving from a LAN to WAN environment.
Augmenting RFC 2544 and/or Y.1564 service activation with an RFC 6349-based test enables the provider to share the customer's network experience, substantially save on OpEx, and dramatically increase first-time customer satisfaction, leading to higher customer loyalty and increased profitability.

Delivering Exceptional VoLTE Service Quality

08/08/2014

Voice is, and will continue to be, a core mobile service. VoLTE is the voice service of the future, embracing better quality, faster connection times, and the integration of rich communication services. VoLTE delivers many operator advantages as well as user advantages over today’s voice services. However, as we have seen, VoLTE is not without its challenges. To be successful in delivering a good VoLTE customer experience, operators will need to be able to test, troubleshoot, manage, and optimize both the network and services to ensure they meet user expectations.
