Network cables are provided via spool cartridges remove ably held inside snap-in cassettes that again are slideably inserted and snap arrested in a rack mountable chassis. The network cables are spring loaded spooled such that they autonomously retract upon unplugging and such that they are straightened while plugged in. Each snap-in cassette has a rear connector that is snap connected to the spooled network cable via an externally releasable connector pair inside the snap-in cassette. The network cables are spooled around a continuously rotating contact hub configured for high frequency signal transfer. The rear connectors reach through the chassis for a centralized network connection. The chassis is dimensioned in conjunction with well known computer rack standards for simple integration into server station architectures. The dual level modularity of spool cartridges inside the snap-in cassette inside the chassis provides for maximum system flexibility and maximum network connections.
