一种光纤通讯用IEEE1394b-PCI光纤接口卡
摘要：
本实用新型公开了一种光纤通讯用IEEE1394b-PCI光纤接口卡，包括链路层芯片、物理层芯片、第一、第二、第三光模块和电源监控芯片。本实用新型通过IEEE 1394b链路层芯片TSB82AA2初始化有关的PCI配置空间，通过内部的主机接口、先进先出存储器和物理/链路层接口来实现IEEE 1394b数据包的传输和接收。物理层芯片TSB81BA3实现仲裁机制，对收发信号进行编码和解码，完成信号转发，与其连接的3个FTLF8519P2BTL光模块负责IEEE 1394b电信号与光信号的相互转换功能，从而实现搭建光总线系统，为电力通信系统提供一种方便、可靠的连接装置。
摘要（英）：

The utility model discloses a IEEE1394b for the optical fiber communication PCI optical fiber interface card, including link layer chip, physical layer chip, first, second, third optical module and power monitoring chip. The utility model discloses a transmission and the receipt of IEEE 1394b packet are realized to the relevant PCI configuration space of IEEE1394b link layer chip TSB82AA2 initialization through host interface, first -in first -out memory and physics / the link layer interface of inside. Physical layer chip TSB81BA3 realizes the arbitration mechanism, to send and receive signals encode with decode, accomplish the signal and transmit, the mutual conversion functions of the IEEE 1394b signal of telecommunication and light signal is responsible for to 3 connected FTLF8519P2BTL optical modules to light bus system is built in the realization, provides a convenience, reliable connecting device for electric power communication system.
