TP-Link TL-SM321A-2 1000Base-BX WDM Bi-Directional SFP Module

TP-LINK's TL-SM321A-2 is developed in accordance with the Small Form Pluggable Multi-Source Agreement (SFP-MSA). As a WDM Bi-Directional optical transceiver, TL-SM321A-2 uses an integrated LC Bi-Directional optical interface connector and the data link is up to 2 km in 9/125 ?m SMF (Single-Mode Fiber).

Also, TL-SM321A-2 incorporates the Digital Diagnostic Monitoring (DDM) feature which is compatible with SFF-8472. DDM supports real-time monitoring of the transceiver, and shows parameters including the transceiver current which transmits/receives optical power and operating temperature.

TP-Link's TL-SM321A-2 is used for short-and medium distance fiber network in practice, and it provides fast and stable gigabit fiber connection for switches, routers, servers, etc.
