Product Description

Wanglink 1.25Gbps single mode dual fiber 1310nm 20km LC interface sfp module


The SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps

and 20KM transmission distance with SMF.

The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a

trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety

requirements.

The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further

information, please refer to SFP MSA.


Features


 Data-rate of 1.25Gbps operation

 1310nm FP laser and PIN photodetector for 20KM transmission

 Compliant with SFP MSA and SFF-8472 with duplex LC receptacle

 Digital Diagnostic Monitoring:

Internal Calibration or External Calibration

 Compatible with SONET OC-24-LR-1

 Compatible with RoHS

 +3.3V single power supply

 Operating case temperature:

Standard : 0 to +70°C

Extended : -20 to +85°C

Industrial : -40 to +85°


Applications
 Gigabit Ethernet

 Fiber Channel

 Switch to Switch interface

 Switched backplane applications

 Router/Server interface

 Other optical transmission systems

Products Show

1) Connected directly to TX data input pins. AC coupled thereafter.

2) Or open circuit.

3) Into 100 ohms differential termination.

4) 20 – 80 %

5) Loss Of Signal is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.

6) Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified value

applied through the recommended power supply filtering network.



7) With worst-case extinction ratio. Measured with a PRBS 27-1 test pattern, @1.25Gb/s, BER<10-12 .

8) Jitter added by receiver (peak to peak). Measured at –18.0dBm average Rx sensitivity, PRBS 27-1 test pattern.


9) Circuit ground is internally isolated from chassis ground.

10) T

FAULT

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.


11) Laser output disabled on T

DIS>2.0V or open, enabled on T

DIS<0.8V.

12) Should be pulled up with 4.7k - 10kohms on host board to a voltage between 2.0V and 3.6V. MOD_DEF(0) pulls line

low to indicate module is plugged in.Transmitter Disabled
