Optelian Announces New Carrier-Class Ethernet Aggregation Card With OTN Transport Capability

OTTAWA and MARIETTA, GA--(Marketwire - February 8, 2011) - Optelian, a trusted designer and manufacturer of optical transport systems, today announced the availability of its new Ethernet aggregation card, further enhancing the capabilities of the company's LightGAIN Optical Networking System. In addition to intelligent Layer 2 switching capability, the new card offers full OTN support on its 10 Gb/s trunk interfaces.

The new card is targeted at Ethernet access, backhaul and metro networking applications. It aggregates up to eight GbE clients onto a single 10 GbE line signal for efficient wavelength usage in packet-based networks. Dual 10 Gb/s trunk ports allow multiple cards to be connected in a linear or ring topology with Layer 2 protection. E-Line and E-LAN type services are supported using IEEE 802.1ad Provider Bridging (Q-in-Q). The card also fully supports Link Aggregation Control Protocol (LACP) using highly customizable and sophisticated load balancing algorithms.

Each trunk interface can be independently configured to LAN or WAN PHY, allowing the card to also act as a 10 Gb/s LAN-to-WAN PHY converter. OTN wrapping can be enabled on each trunk interface using either standard G.709 forward error correction (FEC) or Super FEC, providing reach extension and full OTN trace and tandem connection monitoring capabilities for trunk port connections. All configuration is done remotely via Optelian Network Manager (ONM) or through a local craft interface.

"We are firmly committed to supporting OTN capabilities across our entire portfolio," said Sheldon Walklin, Optelian CTO. "In addition to reach extension and comprehensive path monitoring, OTN's FEC essentially provides an error-free connection between Layer 2 trunk ports under normal variations of power, OSNR and other optical impairments. This cleanly decouples trunk link quality from Layer 2 packet loss mechanisms. Moreover, unlike Layer 2 signal quality monitoring methods, OTN accounts for every bit transmitted."
