TP-Link SM321B-2 1000Base-BX WDM Bi-Directional TX:1310nm/RX:1550nm 2km SFP Module

TP-Link´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.
