Product Description

1.25Gbps SFP Bi-Directional Transceiver, 20KM Reach

Tx1310nm/Rx1550nm

The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of
1.25Gbps/1.0625Gbps 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

 Dual data-rate of 1.25Gbps/1.063Gbps operation
 1310nm FP laser and PIN hotodetector for 20KM transmission
 Compliant with SFP MSA and SFF-8472 with simplex 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 range:
0 °C to +70 °C (Commercial)
-40 °C to +85 °C (Industrial)


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.


1. TD+/- are internally AC coupled with 100Ω differential termination inside the module.

2. Tx Fault and Rx LOS are open collector outputs, which should be pulled up with 4.7k to 10kΩ resistors on the

host board. Pull up voltage between 2.0V and Vcc+0.3V.

3. RD+/- outputs are internally AC coupled, and should be terminated with 100Ω (differential) at the user SERDES


1. Measured with Light source 1310nm (1550nm), ER=10dB; BER =<10^-12 @PRBS=2^23-1 NRZ.

2. When LOS de-asserted, the RX data+/- output is signal output.


1. When high, this output indicates a laser fault of some kind. Low indicates normal operation. And should be pulled up with a 4.7 – 10KΩ resistor on the host board.

2. TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7 – 10KΩ resistor. Its states are:
Low (0 – 0.8V): Transmitter on (>0.8, < 2.0V): Undefined
High (2.0V~Vcc+0.3V): Transmitter Disabled Open: Transmitter Disabled
