Table 1. Pin-out Table
The pin arrangement and definition of this product meets SFP MSA. Table 1 lists the pin description.
Notes:
1. TX_FAULT is an open collector/drain output which should be pulled up externally with a 4.7 – 10 KW resistor on the host board to a supply <
2. TX disable input is used to shut down the laser output per the state table below (internal 10 KW pull-up resistor).
3. Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7-10 KW resistor on the host board to a supply less
4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7 – 10 KW resistor on the host board to
