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 < 0.8V. 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. 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. 4 Optical Communications Systems™ Datasheet Diagram of Host Board Connector Block Pin Numbers and Names Towards Bezel 1 VeeT 2 TX_Fault 3 TX_Disable 4 SDA 5 SCL 6 MOD_ABS 7 RS0 8 RX_LOS 9 RS1 10 VeeR Mechanical Dimensions 5 VeeT 20 TD- 19 TD+ 18 VeeT 17 VccT 16 VccR 15 VeeR 14 RD+ 13 RD- 12 VeeR 11 Towards ASIC Optical Communications Systems™ Datasheet Data Rate (Mbps) Wavelength (nm) Connector Digital Diagnostics Bail Latch Color Max.
