The RB2011 is a low cost multi port device series. Designed for indoor use, and available in many different cases, with a multitude of options. 

The RB2011 is powered by RouterOS, a fully featured routing operating system which has been continuously improved for fifteen years. Dynamic routing, hotspot, firewall, MPLS, VPN, advanced quality of service, load balancing and bonding, real-time configuration and monitoring - just a few of the vast number of features supported by RouterOS.

The Mikrotik RB2011UiAS-RM has an SFP cage for gigabit SFP transceivers and is an ideal solution for FTTH (Fiber To The Home) implementations.
It’s powered by the new Atheros next generation 600MHz 74K MIPS network processor and has 128MB of RAM, and a Level5 RouterOS license. RB2011UAS-RM comes in a rack mount case.

The Mikrotik RB2011UAS-RM has 11 ports: Gigabit SFP cage and five Gigabit Ethernet ports that can be switched together providing affordable wirespeed Fiber-to-Copper converter, and additional five Fast Ethernet ports. Board can be powered by power jack or PoE.

Mikrotik RB2011UAS-RM supports any 1.25G SFP transceivers that is within the SFF Committee specifications for SFP Transceivers. RB2011UAS doesn’t have hardware support for PON (Passive Optical Network) - this hardware support MUST be implemented on SFP transceiver itself. Note that the SFP transceiver is NOT included.

All ethernet ports are fully independent and support 802.1q vlans, and advanced routing protocols including RIPv2, OSPF. and BGP4. Management from GUI or CLI with access through web, telnet, or ssh.
