The compact TP-Link TL-SM321A-2 SFP transceiver is a bidirectional WDM module for the 1000Base-BX standard, providing a stable optical connection over distances up to 2 km on a single-mode 9/125 µm fiber. It features an LC connector, supports DDM (Digital Diagnostic Monitoring), is fully hot-swappable, and complies with the SFP-MSA specification.
The TP-Link TL-SM321A-2 is a reliable bidirectional SFP WDM module designed for gigabit interconnections of devices in small to medium-sized optical networks. Thanks to WDM technology, it uses a single single-mode fiber for both upstream and downstream, saving infrastructure and reducing costs.
Support for DDM per SFF-8472 enables continuous monitoring of key operating parameters such as transmit and receive optical power and operating temperature. The module is SFP-MSA compliant, can be inserted and removed without downtime (hot swap), and is easy to integrate into switches, routers, or servers.
