MIM-1AE3 Module 107Interface Optical Fiber MIM-1AMM uses multi-mode optical cable and MIM-1ASM/MIM-1ASL usessingle-mode optical cable. As all these three modules adopt SC optical fiberconnector, the connector of the connection cable should also be SC connector.The external optical cable suite provides you with optical cables of differentlengths.w WARNING: Laser danger! Do not directly stare at the optical fiber connectorconnected with the laser, in case of the injury that may cause to your eyes.c CAUTION:■ MIM-1ASL module adopts long-haul fiber interface, requiring a transmission atleast longer than 25 km (15.5 in.). If the transmission distance is lower than25km, the interface will be unable to receive signals.■ MIM-1AMM module should be connected with multi-mode optical fiberswhereas MIM-1ASM/MIM-1ASL modules should be connected withsingle-mode optical fibers.n These cables are optional. Please order them when purchasingMIM-1AMM/MIM-1ASM/MIM-1ASL modules; by default, they are not provided.MIM-1AE3 ModuleIntroduction 1-port 34.368 Mbps ATM-E3 interface module (MIM-1AE3) supports:■ Two ATM cell mapping modes: ATM Direct Mapping (ADM) and Physical LayerConvergence Protocol (PLCP);■ Scrambling in data transmission;■ Both line clock (when working as DTE interface) and internal clock (whenworking as DCE interface);■ Four types of test measures, that is, local cell loopback, local payload loopback,remote payload loopback, and remote line loopback.n You are allowed to equip an H3C Series Router with MIM-AE3 modules to its fullcapacity. Yet, you are recommended to install only one MIM-AE3 module on it,whatever its model is, to ensure the performance of some key services.Interface Attributes The interface attributes of MIM-1AE3 are given in the following table:Table 67 Interface attributes of MIM-1AE3Attribute 1AE3 moduleConnector SMBConnector number 2Interface standard G.703, G.751, G.832, G.823Interface rate 34.368 MbpsCable E3/T3 cable (75-ohm coaxial cables)Supported service ATM Traffic CBR, rt_VBR, nrt_VBR, UBR
