SONET/SDH Optimizes DWDM Deployment
White Paper A Global 500 financial services firm faced a number of critical data storage and network infrastructure issues. The firm was generating a tremendous amount of transaction and collaborative data, creating new levels of storage requirements and... [28 Jul 2008]
Increasing the Robustness of IP Backbones in the Absence of Optical Level Protection
White Paper Protection and restoration are provided by the IP layer that operates directly over a DWDM infrastructure. First, SONET protection is gradually being removed because of its high cost (while SONET framing is kept for failure detection purposes). [03 Jul 2008]
The Intelligent Optical Network - IP-Style Control in the Optical Domain
White Paper They will bring flexibility and scalability to the optical domain by combining the functionality of SONET/SDH, the efficiency of IP and the capacity creation of DWDM with advanced networking software. [03 Jul 2008]
Business Impact of Transparent Optical Switching
White Paper Furthermore, optical-switching technology is rapidly evolving and will ultimately lead to the long-promised all-optical or photonic network, which naturally succeeds the current DWDM networks. As capabilities grow rapidly in both technologies, it... [03 Jul 2008]
The Effects of Demand Levels and Number of Wavelengths on the Economics
White Paper To meet the projected demand for connections, network operators have the option of using a network with traditional SONET equipment or a DWDM network with direct interfaces between client network elements and the DWDM equipment. [03 Jul 2008]
Cost Comparison Between IP-Over-DWDM and Other Core Transport Architectures
White Paper Cisco recommends an alternative architecture called IP over DWDM, which eliminates the need for Optical to Electrical to Optical (OEO) conversion equipment between the router and the optical layer (including both transponders and SONET gear) by... [15 May 2008]
OC-192c/STM-64c and 10 Gigabit Ethernet WAN PHY
White Paper Both of these interfaces support transmission at 9.6 Gbps, support SONET/SDH framing, and can be connected to SONET/SDH ADM or DWDM gear. The introduction of 10 Gigabit Ethernet (10 GbE) WAN PHY into the IP/Ethernet networking community has led to... [07 Feb 2008]
Choosing the Right Metropolitan Ring for Your Business
White Paper Dense Wave Division Multiplexing (DWDM) addresses these same requirements, but can also support more protocol options, a Storage Area Network, preferred protection options, or other bandwidth-heavy applications. [02 May 2007]
Efficient Transport of Storage and Ethernet Across Hybrid DWDM and SONET/SDH Networks
White Paper This paper describes an innovative solution to efficiently transport Gigabit Ethernet and Storage Area Network (SAN) protocols from Multiple Dense Wavelength-Division (DWDM) access rings across the core SONET/SDH network. [06 Oct 2006]
Dynamic Multiservice Delivery With Reconfigurable DWDM Networks
White Paper Traditional dense wavelength-division multiplexing (DWDM) networks, whether hub and-spoke or mesh architectures, have significant challenges meeting the dynamic wavelength demands for user services. Service providers and enterprises rely on... [02 Nov 2005]
Carrier Network Infrastructure for Integrated Optical and IP Network
White Paper For backbone and metropolitan optical networks, Hitachi provides SONET/SDH and DWDM transmission systems. As more and more services become available on the Internet, carrier IP networks are becoming more of a social infrastructure. [08 Dec 2004]
Multiservice Optical Networks for Cable MSOs
White Paper Key topics will include Ethernet over Sonet/SDH for resilient transport of Ethernet-based video, and Metro DWDM for scaleable transport of TDM services and 10-Gigabit Ethernet. This free Webinar will examine the key role optical communications... [30 Oct 2004]
Integrated Video Transport Solutions
White Paper Fortunately, the Fujitsu FLASHWAVE family of metro Dense Wavelength Division Multiplexing (DWDM) and SONET products is designed to support broadband cable applications. Cable TV networks are quickly evolving from analog systems used solely for the... [20 Jul 2004]
Enabling Efficient, Dynamic Optical Networks: Applications & Economics of TeraBurst's Optical Core Switches
White Paper To relieve capacity constraints in SONET/SDH rings, dense wavelength division multiplexing (DWDM) technology has been used in point-to-point configurations. SONET ring architectures have become expensive to expand since adding capacity within a... [24 Feb 2004]
Bringing Service Intelligence to Next Generation Metropolitan Area Networks
White Paper Neither traditional SONET/SDH equipment nor emerging metro DWDM equipment can tackle these challenges in today's dynamic, heterogeneous metropolitan environment. More raw bandwidth than ever is available for long-haul transport as fiber... [24 Feb 2004]
