Product Description

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 µm 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.


  • Single-mode SFP Module, WDM Bi-Directional communication on a single fiber.
  • Work with TL-SM321B-2 as a pair and create a full-duplex gigabit path between your switches, storage devices, and server.
  • Wavelength: Tx 1550nm, Rx 1310nm. Data Rate: 1.25Gbps. Port Type: LC Simplex.
  • Always keep the protective dust plug on the SFP's optical bores until you are ready to make a connection.
  • Compatible with all SFP ports on TP-Link product including JetStream switches, and media converter MC220L.
