Notes:
1. 1000BASE-LX. Tested with a 2
7
– 1 PRBS. (Transceiver data rate selected through the 2-wire bus in accordance with SFF-8472 Rev. 10.3. Soft RS0 is set at Bit3, Byte
110, Address A2h. Soft RS0 default state on power up is ‘0’ LOW, and the state is reset following a power cycle. Writing ‘1’ HIGH selects max. data rate operation. Trans-
ceiver data rate is the logic OR of the input state of the RS0 pin and soft RS0 bit. Thus, if either the RS0 pin OR the soft RS0 bit is HIGH, then the selected data rate will be
9.95 and 10.3 Gb/s. Conversely, to select data rate 1.25 Gb/s, both the RS0 pin and the soft RS0 bit are set LOW.)
2. 10GBASE-LR/LW. Tested with a 2
