Notes:

1. “x” can be specified by the customer. The current available wavelengths are: 1471, 1491, 1511, 1531,

1551, 1571, 1591, 1611nm.

2. The optical power is launched into 9/125 SMF.

3. Measured with a PRBS 2

4. Internally AC-coupled.

5. If Pin 3 (TX Disable) is left open, TX is disabled

6. The 1610nm signal can also be received while the sensitivity is degraded.

7. Worst-case condition, measured with a PRBS 2

8. Worst-case condition, measured with a PRBS 2

9. It is for 80km transmission over G.652 SMF, measured with a PRBS 2

better than or equal to 1×10

10. AC-coupled CML logic family.

EEPROM Information

The SFP MSA defines a 256-byte memory map in EEPROM describing the transceiver’s capabilities,

standard interfaces, manufacturer, and other information, which is accessible over a 2 wire serial interface at

the 8-bit address 1010000X (A0h). The memory contents refer to Table 6.
