The Fujitsu FC9565W8C1 is an 88-channel Wavelength Selectable Switch (WSS) module for the FLASHWAVE 9500 platform, part of its reconfigurable optical add/drop multiplexer (ROADM) architecture.
It’s used to route individual DWDM wavelengths through the ROADM without manual patching, supporting the platform’s colorless, directionless, contentionless (CDC) add/drop capability. Available through TelecomLeasing for purchase or lease.
