Pair provide faster line cards
Parama Networks and Finisar Corp are working to give service providers a fast and simple method to upgrade high-capacity Sonet or SDH circuits used in metro, regional and long-haul core networks.
Parama Networks and Finisar Corp are working to give service providers a fast and simple method to upgrade high-capacity Sonet or SDH circuits used in metro, regional and long-haul core networks By combining the software-selectable line rate capabilities of the Parama ADM-on-a-chip with the Sonet/SDH multirate SFP optical transceivers from Finisar, a new optical line card can be automatically reconfigured to upgrade high-capacity circuits to faster line speeds in seconds, instead of days or even weeks

Optical cables slash power needs
Laserwire uses fibre optic technology for the transmission of data while reducing the weight, density and power consumption of copper wire.
Optical products offer copper alternative
The Longwave fibre channel SFP+ 1310nm transceivers support 1.4km and 10km transmission over single-mode fibre.
Now a carrier can start with a relatively low-capacity and inexpensive link (eg OC-3) and upgrade it to a higher speed OC-12 or OC-48 link by simply selecting the new line rate via a network management system.
Pluggable "pay as you grow" capability has existed for years at the network edge, where inexpensive "plug and play" silicon-based products accommodate the lower-speed, sub-Sonet/SDH rate connections found there.
This new combined solution moves all configuration into software thus speeding upgrades substantially.
In the present mode of operations, a carrier desiring to upgrade a circuit has had to temporarily "take down" the network in order to perform a "card swap" in a central office type of facility.
Expensive and time-consuming "truck rolls" are also necessary for remote locations.
This new development is based on Parama's ADM-on-a-chip, introduced in January 2004.
The ADM-on-a-chip features, for the first time ever on a single piece of silicon, all the functions - including crossconnect, line and tributary framers, and overhead processing - necessary to build high-capacity ADM (add/drop multiplexer) and other next generation equipment for Sonet and SDH networks.
"Flexibility is the name of the game when it comes to the evolution of SONET and SDH equipment", said Hemant Bheda, CEO of Parama Networks.
"The capability we are introducing will put OEMs on the path to delivering to their carrier customers the ability to configure transport ports to any rate and any protocol".
"This enables lower inventory and sparing costs and allows for incremental port costs to be incurred in a manner more closely aligned to revenue".
"Software provisionable rate and protocol agnostic ports have been a long-standing goal of carriers - a goal now realised with the ability to inexpensively design multirate, protocol agnostic ports using system-on-a-chip implementations".
