The TL-SM321A-2 from TP-LINK is designed according to the Small Form Pluggable Multi-Source Agreement (SFP-MSA). As a bidirectional optical WDM transceiver, TL-SM321A-2 uses an integrated bidirectional optical LC interface connector and the data link is up to 2 km in 9/125 µm SMF (single-mode fibre).

TL-SM321A-2 also has the Digital Diagnostic Monitoring (DDM) function, which is compatible with SFF-8472. DDM supports real-time monitoring of the transceiver and displays parameters including transceiver current, transmitting/receiving optical power and operating temperature.

TP-Link’s TL-SM321A-2 is widely used for short and medium distance fibre optic networks, providing a fast and stable Gigabit fibre connection for switches, routers, servers, etc.
