Abstract: A modular reconfigurable multi-server system with hybrid optical and electrical switching fabrics for high-speed networking within a wavelength-division-multiplexed based photonic burst-switched (PBS) network with variable time slot provisioning. An optical high-speed I/O module within the multi-server system includes an optical switch with the control interface unit. A server module of the multi-server system statistically multiplexes IP packets and/or Ethernet frames to be transmitted over the PBS network, generate control and data bursts and schedule their transmission. Then, the server E-O converts the bursts, and then transmits the optical bursts to the optical I/O module. The optical I/O module then optically transmits the bursts to the next hop in the optical path after processing the optical control burst to configure the optical switch, which then optically switches the optical data burst without performing an O-E-O conversion.

Abstract: The port for a removable module of a set-top box in a cable television system incorporates guide members of a thermally conductive material to provide a new primary heat dissipation path to manage thermal energy generated by operation of the module. The guide members may also be used to guide the module into proper connection with a module connector which electrically connects the circuit on the module with the circuitry of the set-top box. The guide members may be attached to the chassis of the set-top box or integrally formed in the chassis. Thus, heat from the module is provide directly to the chassis of the set-top box from which it is released by convention into the ambient environment.
