Notes:
1. Accuracy of Measured Tx Bias Current is 10% of the actual Bias Current from the laser driver to the
laser.
X. Two-Wire Interface ID: Data Fields – Address A0h
Byte 13 Rate Select Identifier has been assigned to equal 02h which most accurately
reflects functionality for this product where rate select is enabled through the Rx
Rate_Select pin, per SFF-8572 v10.3. Although SFF-8572 v10.3 indicates that setting
Byte 13 as 02h specifies 8G/4G/2G rates, these rates do not apply to this product which
operates at 1G/10G operation. A future revision of SFF-8572 may utilize unallocated
values that better reflects Rx Rate_Select 1G/10G.
