Abstract:
1. An optoelectronic module for transmitting or receiving optical signals through a fiber-optic link, the module comprising: an electrical I/O port for connecting the module to an external host device, comprising first connection means for providing discrete electrical connections therebetween for a plurality of digital control and status (C&S) signals, said plurality of digital C&S signals comprising digital control signals and digital status signals; an optical port for connecting to the fiber-optic link; functional hardware responsive to the digital control signals, comprising: processing means for processing the plurality of digital control and status signals, the processing means comprising a processor and an FPGA; electrical circuitry for establishing communication paths between the electrical I/O port of the module, the processing means and the functional hardware; wherein the FPGA is disposed in the communication paths between said first connection means on one side, and the functional hardware and the processor on the other side, and programmed with an instruction set for routing each of the digital control and status signals between the first connection means and the processor, and the first connection means and the functional hardware, thereby providing reconfigurability of said routing by downloading a different set of FPGA instructions.
