3Com MSR 50, MSR 30, MSR 20 MIM-1AE3 Module, Interface Optical Fiber, Single-mode optical fibers

	MIM-1AE3 Module 107
Interface Optical Fiber	MIM-1AMM uses multi-mode optical cable and MIM-1ASM/MIM-1ASL uses
	single-mode optical cable. As all these three modules adopt SC optical fiber
	connector, the connector of the connection cable should also be SC connector.
	The external optical cable suite provides you with optical cables of different
	lengths.
	WARNING: Laser danger! Do not directly stare at the optical fiber connector
w connected 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 at
	least longer than 25 km (15.5 in.). If the transmission distance is lower than
	25km, the interface will be unable to receive signals.
	■ MIM-1AMM module should be connected with multi-mode optical fibers
	whereas MIM-1ASM/MIM-1ASL modules should be connected with
	single-mode optical fibers.
n	These cables are optional. Please order them when purchasing
	MIM-1AMM/MIM-1ASM/MIM-1ASL modules; by default, they are not provided.
MIM-1AE3 Module
Introduction	1-port 34.368 Mbps ATM-E3 interface module (MIM-1AE3) supports:
	■ Two ATM cell mapping modes: ATM Direct Mapping (ADM) and Physical Layer
	Convergence Protocol (PLCP);

■ Scrambling in data transmission;

■ Both line clock (when working as DTE interface) and internal clock (when working 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 full capacity. 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.
