Description:
Juhua’s SFP-B31/55L-F20 Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the 1310nm FP laser and the PIN photo-detector .The module data link up to 20km in 9/125um single mode fiber. 
 
Applications:
Switch to Switch Interface
Fast Ethernet
Switched Backplane Applications
Router/Server Interface
Other Optical Links
 
PIN Description:
1. Circuit ground is internally isolated from chassis ground.
2. Laser output disabled on TDIS >2.0V or open, enabled on TDIS<0.8V
3. 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.
4. This is an optional input used to control the receiver bandwidth for compatibility with multiple data rates (most likely Fiber Channel 1x and 2x Rates).If implemented, the input will be internally pulled down with > 30k鈩 resistor. The input states are:
    Low (0 – 0.8V):           Reduced Bandwidth
    (>0.8, < 2.0V):            Undefined
    High (2.0 – 3.465V):     Full Bandwidth
    Open:                         Reduced Bandwidth
5. LOS is open collector output should be pulled up with 4.7k - 10kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
