The Ericsson ROJ2081301/10, known as the MMU2B, is a modem unit used within the Ericsson MINI-LINK family of point-to-point microwave transmission systems. Fitted in the indoor/subrack side of a MINI-LINK node, the MMU2B performs modulation and demodulation of the radio traffic carried over the microwave hop, working with the paired radio unit to keep the link’s payload synchronised across the connection. As the B hardware variant of the MMU2 modem unit line, it is supplied as a maintenance replacement for existing MINI-LINK installations rather than new-build hardware, and continues to be sourced by operators supporting legacy microwave backhaul networks. Tech-Star (UK-based, shipped worldwide) stocks tested Ericsson MINI-LINK modem units including the MMU2B; get in touch to confirm it matches your specific MINI-LINK configuration before ordering.
