The TP-LINK TL-SM321A enables WDM technology to transfer data over one optical fiber bidirectionally. It lets you communicate up to a distance of 10 kilometers with a great bit rate of up to 1.25 Gbps.

TP-LINK TL-SM321A is enough to insert a swtiche into the SFP slot or a media converter (such as MC220L). Power is directly from these devices. It is also equipped with a holder to easily eject the SFP card from the slot. On the other hand, you need to use the TL-SM321B module, which you can find in the related products.
