Part Number: TIDA-00928
Hello,
In TIDA-00928, VAGO_AFBR-5803Z is used.
It says Input Optical Power Minimum at Window Edge is -33.9dBm. Signal Detect – Deasserted is -45dBm.
Between -33.9dBm and -45dBm, DP83822 won't de-assert but input power is out of min value.
DP83822 says SD of opto-module is connected to LED_1 as below
"The LED_1 pin is not used in design and that, if the electrical link between the fiber module and the DP83822 is broken, disconnected or otherwise disrupted, the link will recover only by initiating a soft reset through MDIO/MDC interface."
I am wondering if DP83822 becomes to lose re-establishment link between -33.9dBm and -45dBm.
Would you advise us about this?
Best regards,
Toshihiro Watanabe
