8.3. I2C-Bus – LWC Diagnostic
The TPS-1 provides two “I
2
C Interface Lines” for fiber optics diagnostic purposes. The recommended AVAGO transceiver (AFBR-5978Z) features
internal registers that can be read by the I
2
C interface. The transceiver can deliver diagnostic information via the I
2
C interface. If signal quality is
dropping, an alarm indication can be sent to the controller.
