Finisar extends Fibre Channel, Ethernet
Finisar`s Network Products Division has begun evaluation shipments of the Opticity 3000, a fiber-optic link extender and multiplexer for Fibre Channel and/or Gigabit Ethernet networks. General availability is scheduled for November.
The Opticity 3000 is a follow-on to Finisar`s FLX link extenders, which support only one channel and point-to-point connections. In contrast, the Opticity 3000 supports point-to-point and ring configurations, aggregating multiple links on a single fiber-optic cable pair, and wave division multiplexing (WDM).
With eight link modules per chassis, up to 128 channels can be multiplexed over a fiber-optic cable ring. Potential applications include campus-wide or metropolitan storage area networks (see diagram).
Unlike traditional WDM products, which employ only optical technology, the eight-channel Opticity 3000 combines optical and digital technologies for protocol-specific functionality. This can result in a number of benefits, including distance buffering, digital jitter reduction, and link statistic reporting.
In a point-to-point configuration, the Opticity 3000 extends link connections up to 40km (compared to 10km for standard Fibre Channel and 5km for Gigabit Ethernet).
In a ring configuration, connections can be extended up to 30km between sites, or a total of 120km.
The extender/multiplexer comes in a 19-inch rack-mountable chassis, and can be managed remotely via SNMP, Telnet or over the Web.
