This converter allows you to transform data transfer values measured in FireWire (IEEE-1394) units into STS3c (payload) units, facilitating mapping of device data streams to optical transport network capacities.
How to Use This Tool?
-
Enter the value in FireWire (IEEE-1394) units you wish to convert.
-
Select FireWire (IEEE-1394) as the source unit and STS3c (payload) as the target unit.
-
Click convert to see the equivalent STS3c (payload) value based on the standardized rate.
Key Features
-
Converts data transfer rates between FireWire (IEEE-1394) and STS3c (payload) units.
-
Supports high-speed data rate conversions for telecommunications and media applications.
-
Browser-based and straightforward interface for rapid unit conversions.
Examples
-
1 FireWire (IEEE-1394) is approximately 2.6607 STS3c (payload).
-
5 FireWire (IEEE-1394) units convert to about 13.3035 STS3c (payload).
Common Use Cases
-
Mapping high-speed FireWire data streams to SONET STS-3c payload channels for network integration.
-
Linking digital camcorder data transfers to backbone optical links.
-
Facilitating leased-line services with ~155 Mbps circuits in enterprise networks.
Tips & Best Practices
-
Verify device generation to confirm exact FireWire transfer speeds before converting.
-
Consider overhead and framing bytes impacting usable payload in STS3c units.
-
Use conversions to plan integration of device-level transfers into optical networks accurately.
Limitations
-
Actual usable STS3c payload is slightly less than calculated due to SONET framing and overhead.
-
FireWire speeds vary between device versions; the tool assumes nominal maximum rates.
-
STS3c reflects physical layer capacity and may not encompass all protocol overheads.
Frequently Asked Questions
-
What is FireWire (IEEE-1394)?
-
FireWire (IEEE-1394) is an IEEE-standardized serial bus interface designed for high-speed data transfer, supporting both isochronous and asynchronous streams with minimal host intervention.
-
What does STS3c (payload) represent?
-
STS3c (payload) is a contiguous transport channel in SONET with a gross line rate of 155.52 Mbps used for carrying high-bandwidth signals over optical networks.
-
Why convert FireWire data rates to STS3c payload units?
-
Converting allows mapping of device-based data transfer rates into standardized optical transport payloads, aiding integration of FireWire streams into backbone or leased-line optical networks.
