zSeries Fiber Cabling Service

The connectivity environment has become much more complex, and proper
planning and installation of fiber cabling is critical to maximize the benefits of high
speed protocols such as FICON, Fibre Channel Protocol, Coupling Facility links and
Gigabit Ethernet. These protocols require planning for different fiber types, new fiber
optic connectors, and current and future data rates to determine optimal
connectivity and cabling options.

problems in the future.
As processor packaging evolves, internal locations for various cable
connections may shift, necessitating longer cables, even though the floor
locations of connected devices have not changed.
