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. 4 Datasheet Diagram of Host Board Connector Block Pin Numbers and Names VeeT 1 VeeT TD2 TX_Fault TD+ 3 TX_Disable VeeT 4 SDA VccT 20 19 18 17 16 Towards Bezel 5 SCL VccR 15 6 MOD_ABS VeeR 14 Towards ASIC 7 RS0 RD+ 13 8 RX_LOS RD12 9 RS1 VeeR 11 VeeR 10 Mechanical Dimensions 5 Datasheet Ordering Information Wavelength (nm) Description Max.
