Fibre Connection
FICON. An IBM set of products and services introduced in 1999 that is based on the Fibre
Channel Standard. FICON technology uses fiber-optic cables as the data transmission
medium, and significantly improves I/O performance (including one Gbps bi-directional data
transfer). FICON is designed to coexist with ESCON™ channels, and FICON-to-ESCON
control unit connections are supported.
