Digital Diagnostics Functions:

  • GAOTek GAO-SFPBD-101 series transceivers support the 2-wire serial communication protocol as defined in the SFP MSA1. It is very closely related to the E2PROM defined in the GBIC standard, with the same electrical specifications.
  • Additionally, GAOTek SFP Transceivers provide a unique enhanced digital diagnostic monitoring interface which allows real-time access to device operating parameters such as transmitter optical power, receiver optical power, transceiver temperature, transceiver supply voltage and laser bias current. It defines an alarm system and warning flags, which alerts the end users when particular operating parameters are outside of a factory set normal range.
  • Standard SFP Serial id provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer and other information.
  • SFP MSA defines a 256-byte memory map in EEPROM that is accessible over a 2 wire serial interface at the 8 bit address 1010000X (A0h). The interface is identical to, and is thus fully backward compatible with both the GBIC Specification and the SFP Multi Source Agreement.
  • The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. The memories are organized as a series of 8-bit data words that can be addressed individually or sequentially.
  • Digital diagnostics for the GAO-SFPBD-101 are internally calibrated by default.

Notes:

  1. Circuit ground is internally isolated from ground.
  2. Laser output disabled when it is open or TDis > 2.0V, enabled on TDis < 0.8V.
  3. Should be pulled up with 4.7kΩ to 10kΩ on host board to a voltage between 2.0V and 3.6V.MOD_DEF (0) pulls the line low to indicate the module is plugged in.
  4. This is an optional input used to control the receiver bandwidth for compatibility with multiple data rates (most likely Fiber Channel 1x and 2x Rates).If implemented, the input will be internally pulled down with > 30kΩ resistor. The input states are:
  • Low (0 – 0.8V) : Reduced Bandwidth
  • (>0.8, < 2.0V) : Undefined
  • High (2.0 – 3.465V) : Full Bandwidth
  1. Open : Reduced Bandwidth
  2. Loss of signal is open collector output.
    • It should be pulled up with 4.7 kΩ to 10 kΩ on host board to a voltage between 2.0V and 3.6V.
    • Logic 0 indicates normal operation.
    • Logic 1 indicates loss of signal.
