MIM-1POS
Introduction
MIM-1POS represents the 1-port SDH/SONET interface module. It supports interface rates up to
155.52 Mbps (STM-1/OC-3).
The MIM-1POS can use the protocols such as PPP, Frame Relay and HDLC at the data link layer and
IP at the network layer. It allows direct transmission of packets over SONET/SDH. It supports:
z
Four SFP types: multi-mode short-haul (1310 nm), single mode medium-haul (1310 nm), single
mode long-haul (1310 nm), and single-mode ultra-long haul (1550 nm).
