3. Should be pulled up with 4.7k - 10 kohms on host board to a voltage between 2.0V and 3.6V.
MOD_DEF(0) pulls line low to indicate module is plugged in.
4.
For Rate Selectable version only:
In accordance with SFF Committee SFF-8079 Draft, Rev.1.6,
Table 3. Note that rate select can also be set through 2-wire bus in accordance with SFF-8472

at Bit
3, Byte 110, Address A2h (note: writing ‘1’ selects full bandwidth operation). Rate select is the logic
OR of the input state of Rate Select Pin and 2-wire bus. Non Rate Selectable version can operate at 1x,
2x, 4x Fibre Channel independent of rate select pin setting.
5. LOS is open collector output. Should be pulled up with 4.7k – 10 kohms on host board to a voltage
between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

Notes:
1. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
2. High Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
3. Low Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
4. Also specified to meet curves in FC-PI-2 Rev 10.0 Figures 18, 19, and 20, which allow trade-off
between wavelength, spectral width and OMA.
5. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average
power.
6. Unfiltered, 20-80%. Complies with FC 4x eye mask when filtered.
7. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye masks when filtered.
8. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and
Δ
DJ.
9. Applicable for Rate Selectable version only in low bandwidth mode.
