What Is This Tool?
This tool allows you to convert data transfer rates from STM-4 (signal), a high-speed optical network unit, to SCSI (LVD Ultra80), a storage interface unit, facilitating comparisons and integration between telecom and storage technologies.
How to Use This Tool?
-
Enter the value in STM-4 (signal) units you wish to convert.
-
Select STM-4 (signal) as the input unit and SCSI (LVD Ultra80) as the output unit.
-
Click the convert button to calculate the equivalent amount in SCSI (LVD Ultra80).
-
Review the result and use it to compare or plan data transfer between network and storage systems.
Key Features
-
Converts STM-4 (signal) data rates to SCSI (LVD Ultra80) values accurately.
-
Browser-based interface for quick and simple use.
-
Supports data transfer unit conversions relevant to telecom and enterprise storage.
-
Includes contextual information for both STM-4 (signal) and SCSI (LVD Ultra80).
-
Provides example conversions to guide users.
Examples
-
5 STM-4 (signal) converts to 4.86 SCSI (LVD Ultra80).
-
10 STM-4 (signal) converts to 9.72 SCSI (LVD Ultra80).
Common Use Cases
-
Regional or inter-city optical backbone link rate comparisons in telecommunications.
-
Integration of high-speed optical data rates with legacy storage interfaces in data centers.
-
Assessing data transfer rates between telecom infrastructure and enterprise storage environments.
Tips & Best Practices
-
Understand the context of the units to apply conversions appropriately in telecom or storage scenarios.
-
Use this tool for nominal data transfer rate conversions, not for real-world throughput analysis.
-
Combine conversion results with knowledge of protocol differences for accurate system planning.
Limitations
-
The conversion represents nominal transfer rates and does not consider protocol or operational overhead.
-
STM-4 is expressed in megabits per second, whereas SCSI (LVD Ultra80) bandwidth is measured in megabytes per second.
-
Interface and protocol differences reduce direct interchangeability despite similar data rates.
Frequently Asked Questions
-
What does STM-4 (signal) represent in data transfer?
-
STM-4 (signal) is a standardized optical transmission frame in the Synchronous Digital Hierarchy used for multiplexing and transporting digital traffic at a rate of 622.08 Mbit/s.
-
What is SCSI (LVD Ultra80) used for?
-
SCSI (LVD Ultra80) is a Low Voltage Differential SCSI interface providing up to 80 megabytes per second transfer rate, commonly used for connecting high-performance storage devices.
-
Why is the conversion between STM-4 and SCSI not always straightforward?
-
Because STM-4 and SCSI measure data rates using different units and protocols, conversion reflects nominal rates without accounting for protocol overhead or practical throughput differences.
Key Terminology
-
STM-4 (signal)
-
A synchronous digital hierarchy optical transmission frame with a nominal rate of 622.08 Mbit/s, used in telecom networks for multiplexing digital traffic.

SCSI (LVD Ultra80)
-
A Low Voltage Differential variant of Ultra2 SCSI providing 80 megabytes per second bandwidth over a 16-bit wide bus commonly used in storage interfaces.
-
Data Transfer Rate
-
The speed at which data is transmitted from one place to another, often measured in bits or bytes per second.
