Interface.
1.1 Description
Ampex provides three models of the ATM 300 Series Tape Recorder Interface:
•
ATM 300 - Multimode fiber physical layer interface
•
ATM 300S - Singlemode fiber physical layer interface with SyncStart
•
ATM 300M - Multimode fiber physical layer interface with SyncStart
These three units convert OC-3 (Optical Carrier) data to HOTLink™ serial data for recording
to an Ampex DIS tape drive. During playback, the units convert HOTLink serial data from the
DIS tape drive to OC-3 optical data at a continuous 19.44 megabytes (MB) per second.
Figure 1 shows a typical single unit configuration.
