Average launch/receive power, each lane (min) is informative and not the principal indicator of signal strength. A transmitter with launch/ receive power below this value cannot be compliant; however, a value above this does not ensure compliance 2. Hit Ratio 5 x 10^ -5 hits/sample 3.

ATGBICS® All rights reserved. EOE Ref: ATGBICS_40G-QSFP-4SFP-AOC-1001-C_V1 Page 10 of Product Datasheet Pin Descriptions (SFP28) Notes: 1. Open collector/drain output, which should be pulled up with a 4.7 kΩ to 10 kΩ resistor on the host board if intended for use. Pull up voltage should be between 2.0 V to 3.6 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. 2. Laser output disabled on Tx_Disable >2.0 V or open, enabled on Tx_Disable <0.8 V. 3. LOS is open collector output. Should be pulled up with 4.7 kΩ to 10 kΩ 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. RD-/+: These are the differential receiver outputs. They are internally AC-coupled 100 Ω differential lines which should be terminated with 100 Ω ( differential) at the user SERDES. 5. TD-/+: These are the differential transmitter inputs. They are internally AC-coupled, differential lines with 100 Ω differential termination inside the module. PIN Name Function/Description
