What does SCSI (Fast Ultra Wide) represent?

It is a legacy parallel Small Computer System Interface with a wider data bus and faster signalling, used primarily to connect internal drives and storage devices in older systems.

What is an STM-1 (signal)?

STM-1 is the basic transmission unit of the Synchronous Digital Hierarchy, carrying data at 155.52 Mbit/s, commonly used in telecom fiber backbone links.

Can I directly replace a SCSI (Fast Ultra Wide) connection with an STM-1 signal?

No, the units correspond to different standards—one is a hardware interface and the other a telecom signal—so conversion is for comparison or integration planning rather than direct substitution.

How to Convert from SCSI (Fast Ultra Wide) to STM-1 (signal)?
