Cards can be installed at cross-connects, add/drop multiplexers
or other elements in a variety of network topologies.
Elements include, but are not limited to, terminal multiplexers, add/drop multiplexers
, radio relays and repeaters.
The highly integrated ARROW-2xGE will be used in Metropolitan Area Network (MAN) transport equipment, including Multi Service Provisioning Platforms (MSPP) and add/drop multiplexers. Equipment utilizing the ARROW-2xGE allows service providers to offer carrier-class Ethernet transport over existing SONET/SDH networks, leveraging the performance and reliability of SONET/SDH together with the cost efficiencies of Ethernet.
Direct fabric interconnect allows simple development of Gigabit Ethernet tributary cards for existing SONET/SDH add/drop multiplexers and cross-connects, enabling data services that have previously required high cost system upgrades.
The NIC 2.5G can be utilized to perform functional real-time testing on digital cross connects, add/drop multiplexers
, ATM switches, digital switches, SDH and PDH line repeaters, and network elements.
The transponder is a 10 gigabit-per-second (gbps) optical transmitter/receiver that can be used in dense wavelength division multiplexing (DWDM) systems, inter- and intra-office metropolitan rings, optical add/drop multiplexers
, and Internet Protocol (IP) switches and routers.
The 1Tb/s trial used Ciena s 6500 Packet-Optical Platform solution that combined flexible grid Reconfigurable Optical Add/Drop Multiplexers
(ROADM) with 16QAM coherent modulation to achieve 5b/s/Hz of spectral efficiency over a distance of nearly 1,000 km of uncompensated ELEAF fiber.
The total global consumption of DWDM (Dense Wavelength Division Multiplexing) components used in DWDM system equipment and optical add/drop multiplexers
was worth USD2.85bn in 2000 and is expected to expand to over USD10bn by 2005, according to a new study by ElectroniCast Corp.
Cincinnati Bell Telephone is claiming the position as the first LEC to install a full self-healing Sonet ring for users, having deployed Sonet OC-3 add/drop multiplexers
in March on a fiber-optic network that serves 60 major businesses and other users in downtown Cincinnati.
The new FLEXR GT product, which is a true 32-bit application, is used as a turn-up and maintenance tool for provisioning Fujitsu's network elements (NEs), such as add/drop multiplexers
. Featuring all point-and click capabilities of the earlier 16-bit version, this release also offers support for up to 16 NE log-ins simultaneously and integration of the three FLEXR functions - software download of feature upgrades to local and remote NEs, remote memory backup of the NE configurations and remote memory restoration - allowing network operators to access all three function with a single log-in session.
