¾ Ten 100Base-BX WDM Bi-Directional SFP Modules ¾ Ten Static Shielding Bags ¾ This User Guide ) Note: Make sure that the package contains the above items. If any of the listed items are damaged or missing, please contact with your distributor. 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:

Chapter 2. Features of the product ¾ Single-mode WDM Bi-Directional SFP Module operate at 1550nm/1310nm ¾ Bi-Directional transmit with one fiber which can save cost ¾ Single LC receptacle optical interface compliant ¾ The maximal transmission distance of Single-mode WDM Bi-Directional SFP Module is 15km ¾ Hot-pluggable ¾ RoHS Compliant ¾ International Class 1 laser safety certified

The following will take the installation procedure in the switch for example. ¾ Push the SFP Module into Switch along the track smoothly ¾ Plug fiber into the module, without any configuration manually, the SFP Module can work. Warning: 1. In order to avoid ESD (ElectroStatic Discharge), do not touch the output pins on the module with your hand. 2. 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.
