Notes:

1.

Connected directly to TX data input pins. AC coupling from pins into laser driver IC.

2.

Voltage swing for 1G operation is equivalent to voltage swing in 10G operation (SFF-8431 Rev

4.1).

3.

Into 100

Ω differential termination. Voltage swing for 1G operation is equivalent to voltage swing

in 10G operation (SFF-8431 Rev 4.1).

4.

20 – 80 % . Measured with Module Compliance Test Board and OMA test pattern. Use of four 1’s

and four 0’s in sequence in the PRBS^9 is an acceptable alternative. SFF-8431 Rev 4.1

5.

LOS is an open collector output. Should be pulled up with 4.7k

Ω – 10kΩ on the host board.

Normal operation is logic 0; loss of signal is logic 1. Maximum pull-up voltage is 5.5V.
