To prevent excessive signal distortion over long distances when operating at the OC-192
speed (10 Gbps), optical fiber with special properties must be used.
"Equipment vendors can upgrade OC-48 systems to support OC-192
data rates without reengineering their networks.
Raising the industry bar for service density, capacity and switching flexibility, Turin's Traverse platform integrates Next Generation SONET Add-Drop Multiplexer (ADM), digital cross connect (DCS) and edge switching in a single compact system that scales economically from DS1 to OC-192
per system slot and supports unprecedented 10/100/1000 Mbps Ethernet and OC-N densities.
Most telecommunications carriers offer Gigabit speeds through SONET/SDH infrastructures, with OC-48 (2.5Gbps) at most central offices and OC-192
(10Gbps) throughout the core of their fiber-based telecommunications infrastructures.
To support its new product, AT&T Intelligent Content Distribution Service, AT&T is the first commercial provider to offer Internet Connectivity at speeds of OC-48 (2.5Gbps), as well as the first provider to have fully operational, coast-to-coast OC-192
The company's S/DMS TransportNode OC-192
is a seven-foot, closet-size cabinet of equipment that provides highly sophisticated bandwidth management.
Williams was the first carrier to introduce ATM technology as the core transmission platform, using OC-192
transport systems with DSDM (dense wave division multiplexing) equipment to deliver up to 160 gigabits per second in 16 waves on a single fiber.
Also, the Memphis metro fibre ring is a Wave/SONET-enabled OC-192
ring on the 10 Gigabit backbone designed to provide EarthLink with greater reach into the Memphis market and access to metro and cellular carriers in the city.
The XFP transceivers are small form factor hot pluggable modules designed for 10 GE, 10 Gbit/s Fibre Channel, (SONET) at OC-192
rates, STM-64, 10 Gbit/s OTU-2, and parallel optics links.
Its expanded offering will include private line connections ranging in speeds from T1 to OC-192
; point-to-point and multi-point Ethernet service in speeds ranging from 10Mb/s to 1Gb/s; dedicated Internet access; and colocation, the company claims.
The Datacryptor SONET/SDH encryptor line-up reportedly includes models supporting OC-3, OC-12, OC-48 and OC-192
circuits, ranging from 155Mb/s up to 10Gb/s.
Model number PNI8040, priced at $1250 in 1000+ quantities, features eight software-programmable OC-3 to OC-48 rate SONET and SDH-equivalent rate ports, two OC-192
rate SONET/SDH ports and 40G of digital cross connect capacity.
