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.
