Description

ZK-SFP+-ZR is designed for use in 10-Gigabit Ethernet links up to 80km over single mode fiber. The module consists of 1550 EML Laser, InGaAs APD and Preamplifier in a high-integrated optical sub-assembly. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF8472. The module data link up to 80km in 9/125um single mode fiber.

Absolute Maximum Ratings

Recommended Operating Conditions

Notes: -10 to 60degC with 1.5m/s airflow

Optical Characteristics

Notes：

1. Launched power (avg.) is power coupled into a single mode fiber with master connector.（Before of Life）

2. These are unfiltered 20-80% values.

3. Measured with conformance test signal for BER = 10^–12.@10.3125Gbps, PRBS=2^31-1,NRZ

Electrical Interface Characteristics

Notes: Into 100Ω differential termination.

Pin Description

Notes:

1. Circuit ground is internally isolated from chassis ground.

2. TFAULT is an 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.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.

3. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.

4. Should be pulled up with 4.7kΩ- 10kΩ host board to a voltage between 2.0V and 3.6V. MOD_ABS pulls line low to indicate module is plugged in.

5. Internally pulled down per SFF-8431 Rev 4.1.

6. LOS is open collector output. It should be pulled up with 4.7kΩ – 10kΩ on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
