TP-LINK SFP MODULE SM

Want to reach farther between buildings or outdoor ranges? Convert your SFP-capable switch to a fiber-optic link. It will deliver gigabit speed over single-mode fiber up to 10 km (or to 20 km in certain configurations). Installation takes just seconds: simply insert the LC/UPC fiber connector. That is it – no additional setup or configuration necessary.
