Connected directly to TX data input pins. AC coupling from pins into laser driver IC.
Or open circuit.
Into 100 ohms differential termination.
Unfiltered, 20 – 80 %
LOS is an open collector output. Should be pulled up with 4.7 k – 10 kohms on the host board. Normal operation is logic 0; loss
of signal is logic 1. Maximum pull-up voltage is 5.5 V.
Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified value applied
through the recommended power supply filtering network.
If measured with TJ-free data input signal. In actual application, output TJ will be given by:
TJOUT = DJIN + ΔDJ + √ (TJIN - DJIN ) 2 + (ΔTJ - ΔDJ ) 2

Class 1 Laser Safety per FDA/CDRH, and EN (IEC) 60825 laser safety standards.
Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average power.
Unfiltered, 20-80%. Complies with FC 1x and 2x eye mask when filtered.
TWDP is calculated with a 1.0 equalizer and a 6,860 MHz Gaussian filter for the fiber simulation. Jitter values at λT and λR are
controlled by TWDP and stress receiver sensitivity.
If measured with TJ-free data input signal. In actual application, output TJ will be given by:
TJOUT = DJIN + ΔDJ + √ (TJIN - DJIN ) 2 + (ΔTJ - ΔDJ ) 2

Circuit ground is internally isolated from chassis ground.
TFAULT is an open collector/drain output, which should be pulled up with a 4.7 k – 10 kohms resistor on the host board if
intended for use. Pull up voltage should be between 2.0 V to Vcc + 0.3 V. A high output indicates a transmitter fault caused
by either the TX bias current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal
operation. In the low state, the output is pulled to < 0.8 V.
Laser output disabled on TDIS > 2.0 V or open, enabled on TDIS < 0.8 V.
Should be pulled up with 4.7 k – 10 kohms on host board to a voltage between 2.0 V and 3.6 V. MOD_ABS pulls line low to
indicate module is plugged in.
Rate select can also be set through the 2-wire bus in accordance with SFF-8472 v. 10.1. Rx Rate Select is set at Bit 3, Byte 110,
Address A2h. Tx Rate Select is set at Bit 3, Byte 118, Address A2h. Note: writing a “1” selects maximum bandwidth operation.
Rate select is the logic OR of the input state of Rate Select Pin and 2-wire bus.
LOS is open collector output. Should be pulled up with 4.7 k – 10 kohms on host board to a voltage between 2.0 V and 3.6 V.
Logic 0 indicates normal operation; logic 1 indicates loss of signal.
