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. 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 Distance Range (km) 2.125/4.25/8.5 Gbps SFP+ Transceiver, SM 2125 - 8500 1310 Duplex LC Yes Blue 0 - 10 Model Description Ordering Information SFP-8GD-LR Regulatory and Industry Compliances Class 1 Laser Product, complies with EN 60825-1 and 21 CFR 1040.10 except for deviations pursuant to Laser Notice No. 50. dated June 24, 2007 MSA SFF-8074i; Digital Diagnostic SFF-8472 Certified by one or more of the following agencies: TÜV, UL, CSA RoHS Directive; China RoHS; California RoHS Law, REACH Directive SVHC; WEEE Directive The Quality Management System is certified to ISO 9001 by QMI-SAI Global The Environmental Management System is in compliance with ISO 14001 Warnings Handling Precautions: This device is susceptible to damage as a result of electrostatic descharge (ESD).
