Chapter 1. Introduction  
TL-SM221 Series 100Base-BX WDM Bi-Directional SFP Module is a  
hot pluggable 3.3V SFP (Small-Form-Factor) Bi-Directional  
transceiver module, which adopts WDM (Wavelength Division  
Multiplexing) technology that increases the information carrying  
capacity of fiber via multiplex transmit and receive signals at  
different wavelengths on single strand cable. It’s designed expressly  
for high-speed communication applications that requires rates of up  
to 155Mbit/sec. It can effectively extend the diameter and bandwidth  
of the workgroup. TL-SM221 Series SFP Module can be installed  
inside the Switch which supplies power directly, it also can  
cooperate with TP-LINK products as the table below:

2.  
In order to avoid ESD (ElectroStatic Discharge), do not touch  
the output pins on the module with your hand.  
Avoid directly looking towards the output port of the light  
modules and never locate the working fiber pointing to the  
eyes, otherwise may cause injury to your eyes.
