As I understand it, Cisco is planning on dropping the Linksys name and
calling everything Cisco.  The gear I'm most familiar with is made by
Adtran.  That link is for a switch that's similar to the Adtran 1224,
though it may be closer to the replacement for the 1224, however, I've
forgotten that model number.  With the Adtran gear, you can use a
browser with HTTP or HTTPS or CLI via telnet, SSH or serial port. 
Adtran's AOS is similar to Cisco's IOS.  I have used SFP modules on jobs
where fibre is necessary due to distance.
