TP-Link SM-21 - Fiber Module Card


Description
   Fiber Module Cards are introduced for extending transfer distance, attached to our smart switches. It can extend the distance to several kilometers even tens kilometers which can basically satisfied the distance requirement of LAN. Users can choose whether and which items to use the fiber modules according to the demand in order to low the cost.
Specifications
 There are many kinds of fiber modules. Based on port type, the fiber modules can be divided as the following kinds:
Model No. Connector Transfer Distance Transfer Media
TL-SM21CM SC port 2Km 1300nm, 62.5/125, 50/125 multi-mode fiber
TL-SM21TM ST port 2Km 1300nm, 62.5/125, 50/125 multi-mode fiber
TL-SM21CS-A SC port 20Km 1300nm, 9/125µm single-mode fiber
TL-SM21TS-A ST port 20Km 1300nm, 9/125µm single-mode fiber
TL-SM21CS-B SC port 40Km 1300nm, 9/125µm single-mode fiber
TL-SM21TS-B ST port 40Km 1300nm, 9/125µm single-mode fiber
