Product Details

General:

The products are compliant with the Small Form- Factor Pluggable (SFP) Multi-Source Agreement (MSA) and

SFF-8472. The Digital Diagnostic Monitoring functions as described in SFF-8472 are provided via an I2C serial

interface. The transceiver block diagram is shown as below Fig 1.

The module provides digital diagnostic information of its operating conditions and status, including

transmitting power, laser bias, receiver input optical power, module temperature, and supply voltage.

Calibration and alarm/warning threshold data are written and stored in internal memory (EEPROM).

The memory map is compatible with SFF-8472, as shown in Fig. 2. The diagnostic data are raw A/D

values and must be converted to real world units using calibration constants stored in EEPROM

locations 56 – 95 in A2h.
