FIBER OPTIC EXTENSIONS FOR PCI EXPRESS AND USB BASED SYSTEMS

Fiber optic extension systems allow standard computer peripherals to be installed remotely and operated as though they are connected locally. This ability permits system integrators to use extension systems in applications where PCI and PCI Express cards and USB devices must operate under harsh environmental conditions and a standard computer cannot be used, or where the equipment must be isolated or operated remotely from the computer.

Extension systems are transparent to software applications and drivers, so desktop computers and servers can communicate with the remote equipment with no additional programming. The use of fiber optics provides electrical isolation and the ability to use long cables without compromising performance.

The systems can operate with standard pluggable multi-mode or single-mode SFP transceivers and LC-LC fiber optic cables. Multi-mode transceivers and cables are intended for applications requiring cable lengths up to 500 meters. Single-mode transceivers and cables can extend the operating distance up to several kilometers.

Remote units with appropriate transceivers can operate in the industrial temperature range from -40° to +85° C.

PCI Express over fiber optic extension systems allow PCI and PCI Express cards to operate remotely at distances from a few meters to several kilometers from the host computer, depending on the type of cables and transceivers. Any type of PCI and PCI Express peripherals can be used, including audio, video, graphics, USB, FireWire, SATA, data-acquisition, and network cards. No additional programming and drivers are required. Fiber optic cable provides electrical isolation from the host computer.

USB over fiber optic extension systems allow extend the operating distance of an USB link to several kilometers and provide optical isolation from the host computer. The unique feature of this USB extension is the use of the PCI Express over fiber optic technology. The computer PCI Express bus is extended over a fiber optic cable and a standard USB 3.0 host controller is used in the remote unit. No other solution exists on the market that is fully compliant with the USB 3.0 specification, supports Super-Speed (5.0 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) on each port and provides fiber optic isolation.

Small form factor remote interface modules are designed to easily integrate fiber optic extension solutions into custom embedded systems. The modules provide the same PCI Express and USB extension functionality, can use the same transceivers and fiber optic cables and interface to the same host adapters as full size extension systems.

JCAT USB Card is the ultimate solution for computer audiophiles who want to achieve the best sound quality from their USB DACs and USB-to-S/PDIF converters. The card is designed specifically for low noise high performance audio applications like hi-end audio playback. It uses low noise linear regulators and high quality filters that eliminate noise interference from the host PC. The ultra-low jitter Crystek oscillator and NEC host controller provide the highest audio playback quality.
