TP-LINK SM321A - SFP Module

The TP-Link Omada Gigabit Single-Mode WDM Bi-Directional SFP module provides fiber-optic connectivity for enterprise network infrastructure. This component installs directly into compatible SFP ports on routers, switches, and media converters. Operating on 9/125 µm single-mode fiber, the transceiver extends physical network links beyond the limits of copper cabling. It supports data transfer rates of up to 1250 Mbit/s and uses the 1000Base-BX standard for integration with standard networking hardware.

Connections are made via an LC Simplex fiber-optic interface. The unit uses bi-directional technology to manage incoming and outgoing communication over a single fiber strand. As the device is designed exclusively for wired data transport, it does not contain Wi-Fi hardware or support wireless protocols. The housing measures 55.4 mm in width, 14.6 mm in depth, and 12.9 mm in height, ensuring compatibility with standard mounting cages.
