Multi-Deck Structure WDM Devices for Optical Networks
White Paper By using multi-deck fiber arrays one device can function as both multiplexers and demultiplexers simultaneously. Wavelength Division Multiplexing (WDM) and Demultiplexing (WDDM) devices are considered to be one of the key elements in optical networks. [18 Jul 2008]
Grooming of Arbitrary Traffic in SONET/WDM BLSRs
White Paper SONET add-drop multiplexers (ADMs) are the dominant cost factor in the SONET/WDM rings. They can potentially be reduced by optical bypass via optical add-drop multiplexers (OADMs) and traffic grooming. [10 Apr 2008]
Synchronizing Network Elements on SONET/SDH Rings
White Paper This paper describes the complexity of the high-speed networks by analyzing different popular architectures and takes a look at the challenges in synchronizing various systems such as Add-Drop Multiplexers (ADM), Terminal Multiplexers, Cross... [10 Apr 2008]
Multi-Level Parking Lot: Non-Stop Unmanned Surveillance for Multi-Level Car Park
White Paper A traditional system providing a partial solution to the problem would at the very least have to include a large matrix switcher, motion sensors, time-lapse recorders, multiplexers and a control unit together with cameras and monitors. [22 Nov 2007]
Casema Selects Scientific Atlanta Digital Headend System for the Netherlands
White Paper Casema, which chose a Scientific Atlanta iLYNXTM platform to create an extensive video backbone across its service area in 2002 and 2003, also selected multiple model D9655TM multiplexers from Scientific Atlanta for the new headend. [16 Nov 2007]
Evolution to Enhanced Reconfigurable Optical Add/Drop Multiplexers (eROADM)
White Paper The fast adoption of business and residential broadband services is certainly igniting service providers' and cable operators' momentum. However, their deployment requires the implementation of emerging technologies (such as broadband access... [15 Sep 2007]
Routing Requirements in Photonic Networks
White Paper Conventional optical backbone networks consist of line systems (amplifiers and regenerators), Add-Drop Multiplexers (ADMs) and digital cross-connects. A new generation of optical networks will have the network intelligence to support a wide range... [15 Sep 2007]
WaveTunnel - Accurately Designing Deployable Optical Networks
White Paper It includes detailed equipment modeling that leads to accurate cost models and novel algorithms for validating the designed network against the routing algorithms used for network provisioning, and selecting add-drop multiplexers versus cross... [13 Dec 2006]
ROADM Enabled Optimization in WDM Rings
White Paper For reasons of resiliency and simplicity, DWDM networks are predominantly configured as rings, consisting of fiber links connecting Optical Add-Drop Multiplexers (OADM). Dense Wavelength Division Multiplexing (DWDM) has established itself as the... [28 Nov 2006]
A Reconfigurable Tile-Based Architecture to Compute FFT and FIR Functions in the Context of Software-Defined Radio
White Paper Each tile contains a multiplier, an adder, local memory and multiplexers allowing flexible communication with the neighboring tiles. Software-Defined Radio (SDR) is the term used for flexible radio systems that can deal with multiple standards. [16 Feb 2006]
Transport Solutions for Wireless Networks in North America
White Paper Digital cross-connects, SONET Add/Drop Multiplexers, and Wave Division Multiplexing equipment allow backhaul and traffic management to cope with the ever-increasing demands of network expansion. While many telecoms Service Providers are marking... [11 Oct 2005]
Integrated Data and Control Plane Processing Using Intel IXP23XX Network Processors
White Paper The first network processor offering from Intel built on 90-nm technology, the Intel IXP23XX product line brings together network processing, control processing, and versatile integrated input/output (I/O) to support highly efficient network... [08 Sep 2005]
Xilinx Solutions for SONET/SDH Equipment
White Paper As a result, equipment traditionally supporting only voice traffic such as add/drop multiplexers and digital cross connects must now also support multiple data protocols, faster data rates, and denser port counts. [01 Nov 2004]
German Utility Uses RAD Access Devices for Telecontrol and Voice and Data Communications Network
White Paper ITM developed a future-proof and economical concept using a fiber optic SDH backbone based on Sagem add-drop multiplexers (ADMs). RAD's Megaplex-2104 multiplexers provide transparent transmission of data from process control systems with a V.24... [27 Oct 2004]
Russian Oil Company Taps Into Communications Pipeline
White Paper Deployed in two phases thus far, the SDH network consists of five STM-1 rings equipped with RAD's R-STM-1E add-drop multiplexers, and five STM-4 rings, in which RAD integrated add-drop multiplexers of another vendor to provide a turnkey solution. [27 Oct 2004]
