Patent number: 6185203Abstract: The Fibre Channel standard was created by the American National Standard for Information Systems (ANSI) X3T11 task group to define a serial I/O channel for interconnecting a number of heterogeneous peripheral devices to computer systems as well as interconnecting the computer systems themselves through optical fiber and copper media at gigabit speeds (i.e., one billion bits per second). Multiple protocols such as SCSI (Small Computer Serial Interface), IP (Internet Protocol), HIPPI, ATM (Asynchronous Transfer Mode) among others can concurrently utilize the same media when mapped over Fibre Channel. A Fibre Channel Fabric is an entity which transmits Fibre Channel frames between connected Node Ports. The Fibre Channel fabric routes the frames based on the destination address as well as other information embedded in the Fibre Channel frame header. Node Ports are attached to the Fibre Channel Fabric through links.Type: GrantFiled: February 18, 1997Date of Patent: February 6, 2001Assignee: Vixel CorporationInventor: Stuart B. Berman

Patent number: 5767999Abstract: A module and module guide is disclosed which facilitates user access to electronic circuits such as serial transceiver circuits without need to remove the host system housing or to power down the system. The module and module guide system permits this easy access while maintaining electromagnetic emissions below standard specifications. The module and module guide system also permits hot pluggablity of the circuit into the host system by providing discharge paths for static electricity that might have built up on the outside of the module during handling. The module has a housing with cooling vents and and an EMI shield. The module has guide grooves in the sides of the housing, and at least two connectors, one being a straddle mount connector on the host side and typically serial connectors on the remote side. The module guide has a frame with window forming members, the window for receiving the module.Type: GrantFiled: May 2, 1996Date of Patent: June 16, 1998Assignee: Vixel CorporationInventor: Andrew H.

Patent number: 5642376Abstract: A vertical-cavity surface-emitting laser is disclosed comprising a laser cavity sandwiched between two distributed Bragg reflectors. The laser cavity comprises a pair of spacer layers surrounding one or more active, optically emitting quantum-well layers having a bandgap in the visible which serve as the active optically emitting material of the device. The thickness of the laser cavity is m .lambda./2n.sub.eff where m is an integer, .lambda. is the free-space wavelength of the laser radiation and n.sub.eff is the effective index of refraction of the cavity. Electrical pumping of the laser is achieved by heavily doping the bottom mirror and substrate to one conductivity-type and heavily doping regions of the upper mirror with the opposite conductivity type to form a diode structure and applying a suitable voltage to the diode structure. For radiation in the yellow to green portion of the spectrum, the laser includes an active layer of GaP or AlGaP quantum wells and AlP/AlGaP mirrors.Type: GrantFiled: March 4, 1993Date of Patent: June 24, 1997Assignee: Vixel CorporationInventors: Gregory R.
