What This Product Does
TP-LinkĀ“s SM321B-2 (TL-SM321B-2) is developed in accordance with the Small Form Pluggable Multi-Source Agreement (SFP-MSA). As a WDM Bi-Directional optical transceiver, SM321B-2 (TL-SM321B-2) uses an integrated LC Bi-Directional optical interface connector and the data link is up to 2 km in 9/125 µm SMF (Single-Mode Fiber).
Also, SM321B-2 (TL-SM321B-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 SM321B-2 (TL-SM321B-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.
