Design of Ethernet to Optical Fiber Bridge IP Core Based on SOPC

Abstract

Based on the technology of system on a programmable chip (SOPC), an Ethernet to fiber bridge IP core is developed and implemented in Xilinx FPGAs. The IP core provides a way to interconnect between Ethernet port and optical port, which can be used to address the needs of remote connection and break the transmission distance restriction of cable. The logic design of IP core is done in Xilinx development tools ISE, and then encapsulated into custom IP core in EDK tools, so that the user-defined IP core can be used in embedded system. Build SOPC system with Micro blaze soft-core processor, and add the IP cores into processor platform through Axi4-Stream bus interface. By testing and validating, the results show that Ethernet to optical fiber bridge IP core fulfills the purpose to transmit Ethernet data on optical fiber.
