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. 4 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 Datasheet Data Rate (Mbps) Wavelength (nm) Connector Bail Latch Color Max.
