Sorrento unveils 10G Optical Ethernet Transport line card

JANUARY 12, 2009 -- According to Sorrento, the new OET line card fuses the latest Ethernet and WDM technologies, enabling users to transport and manage multiple Gigabit Ethernet (GbE) circuits on the same line card. As a result, users can reduce costs, increase GbE interfaces up to five times on existing systems, and improve efficiencies for all Ethernet transport applications, say company representatives.

JANUARY 12, 2009 -- Sorrento Networks (search for Sorrento Networks), provider of metro optical access equipment, today launched its 10 Gigabit Optical Ethernet Transport (OET) line card.

According to Sorrento, the new OET line card fuses the latest Ethernet and WDM technologies, enabling users to transport and manage multiple Gigabit Ethernet (GbE) circuits on the same line card. As a result, users can reduce costs, increase GbE interfaces up to five times on existing systems, and improve efficiencies for all Ethernet transport applications, say company representatives.

"By adding a new layer of intelligence to WDM technology, we are providing our customers with end-to-end Gigabit Ethernet and taking them to the next level in bandwidth capacity in the most cost-conscious and efficient way possible," explains Jim Nevelle, CEO of Sorrento Networks.

With the increase in corporate network traffic, storage area networks, consumer broadband, and, increasingly, mobile backhaul, the demand for bandwidth continues to grow exponentially. WDM allows service providers and enterprises to accommodate this bandwidth growth and avoid costly new fiber build-outs.

Sorrento's new OET line card offers built-in layer 2 controls that can be switched on to enable customers to control Ethernet traffic and offer more capabilities in their infrastructure. Additionally, this line card allows users to set up a 10G "superstructure" of existing ring optical systems that dramatically increases bandwidth capacity and gives them the ability to support additional data services, claims the company. This means service providers and enterprises can offer Ethernet services to their customers in a matter of days versus months, giving them a significant competitive advantage.

"The OET line card enables Sorrento's service provider and enterprise customers to turn on new Ethernet services quickly, which means a shorter time to Ethernet transport and/or billable revenue," notes Michael Howard, principal analyst and co-founder of Infonetics Research. "This move into a pragmatic and efficient
Ethernet transport over WDM represents a strategic move for Sorrento to address a fast-growing market need."

Transporting multiple Ethernet circuits over multiple node WDM systems has historically required an optical multiplexer coupled with a layer 2 switch. This architecture can be costly due to the amount of equipment involved and the length of time to market. Sorrento claims its OET line card collapses multiple pieces of equipment into one WDM line card that offers multiplexing, electrical ROADM-like functionality, switching and protection, thereby greatly reducing capital expenditures and improving efficiency for all Ethernet transport applications. Sorrento's first OET line card is compatible with its existing GigaMux 1600/3200 optical transport system.

Additional product features include:
• A built-in layer 2 switch that enables add, drop, mux, pass-through, and ROADM-like functionality, which can be manipulated by the customer to be turned on or off as needed;
• Dual 10G line-side support for sub-50-m/sec protection and internal pass-through;
• FEC-enabled 100-km line-side distances;
• Fully pluggable architecture with flexible SFP-based clients and XFP-based line-side; and
• Remote provisioning and management, which eliminates truck rolls.

The Sorrento OET line card will be generally available worldwide on
January 30, 2009.
