PON Series Signal Detect Hysteresis*(note9) Note 7: Measured with a PRBS 223-1 test pattern @1.244Gbps, BER 1X10-10. Note 8: The input power difference between two subsequent high and low burst data. Note 9: LOS Hysteresis(SD signal coincides with the LOS signal inversion) Digital Diagnostic Interface The memory map in the following describes an extension to the memory map defined in SFP-8472. The enhanced interface uses the two wire serial bus address 1010001X (A2h) to provide diagnostic information about the module’s present operating conditions. Eoptolink Technology Inc., Ltd.
