Circuit ground is internally isolated from chassis ground. Laser output disabled on TX Disable >2.0V or open, enabled on TX Disable<0.8V. Should be pulled up with 4.7k - 10kohms 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. LOS is LVTTL output. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

Class 1 Laser Safety. Over case temperature of 0 to 70 °C. The Transmitter Center Wavelength “x” is as specified by the customer. The current available wavelengths are: 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average power. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E) and FC 1x eye masks when filtered. Measured with DJ-free data input signal .In actual application, output DJ will be the sum of input DJ and ΔDJ. Measured with conformance signals defined in FC-PI-2 Rev. 10.0 specifications.
