7.7. Fibre Channel Optical Link Extender
The Fibre Channel Optical Link Extender will not be included in the Escala offering as of 31/01/2001.
7.7.1. Highlights
The FLX-2000 extends the distance of high-speed optical fibers well beyond the 500 m limit of
multimode optical fibers. Finisar’s Optical Link Extenders facilitate new applications such as remote
storage and disaster recovery.
A pair of FLX-2000s extends a link by converting the short-haul copper or multi-mode optical signal
to a long-haul, single-mode signal, and vice versa. Its internal Digital Signal Conditioner re-times the
signal over the long-served over long distances with a bit error rate of 10
-12
or better.
Simple to install, FLX-2000 link extenders include comprehensive system status monitoring and link
diagnostics. The link monitoring and diagnostics provide quick fault detection and isolation.
Integration with network management is provided via an RS232 serial port attached to a local terminal
or modem to allow remote access.
7.7.2. SAN Topologies & Interoperability
Long distance links have been qualified only with one Optical link extender at both ends of the fiber.
Interoperability with other devices on the long-haul optical fiber has not been qualified.
The Optical link extender has been qualified with links up to 10 km. Longer distances can be obtained
in SFR (up to 120 km).
The short-haul connection has been qualified with DAS RAID subsystems, AIX PCI servers, and the
Gadzoox Bitstrip fibre channel hub.
7.7.3. Packaging
The Optical Link Extender is tabletop (and stackable) equipment. Flat mounting on a wall is possible.
Rack mounting kit is not available.
