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:

)Note:
If any abnormal status occurs when the light modules of the device
are hot-switched between 1000Mbps and 100Mbps, please try to
power on the device again.
Chapter 2. Features of the product
¾Single-mode WDM Bi-Directional SFP Module operate at
1550nm/1310nm
¾Bi-Directional transmit with one fiber which can save cost
¾Single LC receptacle optical interface compliant
¾The maximal transmission distance of Single-mode WDM
Bi-Directional SFP Module is 15km
¾Hot-pluggable
¾RoHS Compliant
¾International Class 1 laser safety certified

Chapter 3. Installation Guide
The following will take the installation procedure in the switch for
example.
¾Push the SFP Module into Switch along the track smoothly
¾Plug 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.
