Notes: 1. Circuit ground is internally isolated from chassis ground. 2. Open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. 3. 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. 4. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V. 5. Internally pulled down per SFF-8431 Rev 4.1.
- LOS is open collector output. Should be pulled up with 4.7k – 10k on host board to a voltage between
2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal. Figure 2. Diagram of Host Board Connector Block Pin Numbers and Names on the SFP28 ends. Data Rate Specifications Symbol Min Typ Max Units Ref.
- Supports 25/100 Gigabit Ethernet applications.
- Pre-FEC, tested with a PRBS 231-1 test pattern.
- Assumes FEC provided by host system.
- Better BER spec may be available through customization, as a premium product.
