3.14.4 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 connected with the
laser, in case of the injury that may cause to your eyes.
Caution:
z
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.
z
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.
Note:
These cables are optional. Please order them when purchasing
MIM-1AMM/MIM-1ASM/MIM-1ASL modules; by default, they are not provided.
3.15 MIM-1AE3 Module
3.15.1 Introduction
1-port 34.368 Mbps ATM-E3 interface module (MIM-1AE3) supports:
z
Two ATM cell mapping modes: ATM Direct Mapping (ADM) and Physical Layer
Convergence Protocol (PLCP);
z
Scrambling in data transmission;
z
Both line clock (when working as DTE interface) and internal clock (when working
as DCE interface);
