Abstract
The utility model discloses an external interface device from optical fiber communication to PCI-E bus communication. The device is composed of various optical fiber interfaces (1), a connecting line (2), a processing chip (3) for converting an optical signal to a PCI-E digital signal and a PCI-E bus communication interface (4). The device scientifically conducts communication extension on computers and ingeniously carries out effective conversion from the optical signals of each optical fiber of a plurality of interfaces to the digital signals of PCI-E through the processing chip (3) for converting the optical signal to the PCI-E digital signal. The entire device adopts a plurality of optical fibers and protocols for transmission.
Description
Technical field
The utility model relates to a kind of compunication signal conversion equipment, especially a kind of external interface device that optical fiber communication is converted to the PCI-E bus communication.
Background technology
Along with development of computer, digital data transmission becomes the bottleneck that influences computer and the lifting of external equipment communication performance.Though have many can be to its method of expanding, practical is few of.The performance boost of bus is enough to produce revolutionary change far from, and the performance of lifting is limited.
Nowadays the internal interface of computer has developed into PCI, PCI-X, PCI-E, SATA, SCSI etc., and based on suitable perfect of the equipment of PCI structure, technology is also quite outstanding.How optical fiber communication is converted to perfect PCI-E bus communication? become the direction of present effort.
Summary of the invention
The purpose of this utility model provides the external interface device of a kind of optical fiber to the PCI-E bus communication, by the rich experiences of being accumulated for many years, analyses in depth research, can effectively improve existing disappearance, and better ease of use can be provided.
Particular content:
A kind of optical fiber is to be made of light signal conversion PCI-E digital signal processing chip, line, optical fiber interface and PCI-E bus communication interface to the external interface device of PCI-E bus communication.Light signal conversion PCI-E digital signal processing chip is equipped with in device inside, and device is to be connected by optical fiber interface with each fiber port, and device then is to be connected by the PCI-E bus communication interface with computer PCI-E bus.Whole optical fiber is in the external interface device of pci bus communication can be placed on computer or be placed on outside the computer.
The utility model has adopted the mode of light signal and digital signal conversion, and the PCI-E structure of utilizing computer itself to have is carried out the communication expansion to computer.Ingeniously the light signal of each optical fiber of a plurality of interfaces and the digital signal of PCI-E are effectively changed by light signal conversion PCI-E digital signal processing chip, whole device can provide multiple optical fiber communication mode and interface, can adopt polytype optical fiber and agreement to transmit.Not only can determine to improve existing disappearance, and better ease of use can be provided.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
