Chapter 1. Introduction

TL-SM321 Series 1000Base-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 1.25Gbit/sec. It can

effectively extend the diameter and bandwidth of the

workgroup. TL-SM321 Series SFP Module can be installed

inside the Switch which supplies power directly, it can

cooperate with TP-LINK products as the table below:
