Such on-chip integration avoids the complex alignment issues associated with manually connecting different and larger components with optical fibers, and avoids the cost and space associated with manufacturing, assembling and packaging the separate components of Add/Drop Multiplexers
Alidian's Optical Service Network (OSN) product family is a powerful set of service add/drop multiplexer
solutions that covers the entire metro network from access to core.
About the DWDM add/drop multiplexer
supplied by Alcatel
Omnia Communications, Inc., Marlborough, Mass., a new provider of next-generation access solutions for the telecom industry, has introduced the AXR 500, the first next-generation Add/Drop Multiplexer
(ADM) for carriers' Synchronous Optical Network (SONET)-based metropolitan area networks.
The optical transport system must consist of ROADM (re-configurable optical add/drop multiplexer
) nodes accordance with ITU-T Rec.
The backbone connectivity between the Sapphire PoPs is provided with the Optical Metro 4150 compact STM-4 add/drop multiplexer
that supplies customer access to traditional TDM services on one platform, and the Nortel Multiservice Switch 15000 that enables future VoIP implementation by acting as a Media Gateway, the company said.
ADVA Optical Networking will be using its FSP 3000 platform with Reconfigurable Optical Add/Drop Multiplexer
(ROADM) technology and its new Network Hypervisor to showcase how flexible SDN-based networks can become.
Fujitsu confirmed that its FLASHWAVE 4500 multiservice provisioning platform (MSPP), FLASHWAVE 7420 managed wavelength platform and FLASHWAVE 7500 reconfigurable optical add/drop multiplexer
(ROADM) platforms are available to members of The Quilt, for deployment within their regional optical networks.
This latest release integrates wideband TDM cross-connect functionality including DS3 test access to an already versatile CityStream platform which also offers ATM service access multiplexer and ATM switch (announced in March 2002) functionality combined with Next Generation SONET add/drop multiplexer
DWDM systems typically include a pair of terminals, one or more optical amplifiers, and, in some cases, an optical add/drop multiplexer
In addition, Nortel is providing optical solutions including its Optical Metro 4150 multi-service next-generation SDH platform, Optical TN-1X add/drop multiplexer
and Optical Metro 3500 DWDM-capable next-generation SONET platform.
The platform, equipped with third generation WaveLogic Coherent Optical Processors, leverages an agile ROADM (Reconfigurable Optical Add/Drop Multiplexer
) optical layer, which enables fast and efficient 100G connections between central locations.
