TP-LINK Omada ISM321B-20 - SFP Module, Gray

The TP-Link Omada ISM321B-20 1000Base-BX WDM bi-directional industrial SFP module provides wired network connections for industrial infrastructure. Designed for industrial network switches, this transceiver acts as a direct hardware interface for single-mode fiber (SMF) setups. It supports data transfer rates up to 1250 Mbit/s. By using Wavelength Division Multiplexing (WDM) on a single fiber strand, the module reduces the amount of physical cabling required, ensuring consistent transmission across large-scale facility deployments.

The module uses a standard pluggable form factor and connects via an LC Simplex port. It is compatible with Omada network equipment featuring an available optical slot. The hardware supports hot-swapping, allowing administrators to insert or remove the unit without powering down the host device. Integrated Digital Diagnostics Monitoring (DDM) provides real-time data on link health, enabling technicians to verify optical signal quality during active operation.
