What Is This Tool?
This tool facilitates the conversion of data transfer rates from terabyte per second (SI definition) to STS3c (payload), helping users translate very high-speed digital throughput into equivalent SONET payload channels.
How to Use This Tool?
-
Enter the data transfer rate value in terabytes per second (SI def.)
-
Select STS3c (payload) as the target unit
-
Initiate the conversion to obtain the equivalent STS3c (payload) rate
Key Features
-
Converts between terabyte/second (SI definition) and STS3c (payload) data transfer units
-
Browser-based and easy to use with no software installation
-
Supports network capacity planning and legacy optical transport network integration
Examples
-
2 Terabytes/second converts to 106428.27 STS3c (payload)
-
0.5 Terabytes/second converts to 26607.07 STS3c (payload)
Common Use Cases
-
Mapping high data rates to SONET payload channels for optical transport planning
-
Specifying backbone optical link capacities carrying Ethernet or IP traffic
-
Provisioning leased-line services and client signal transport over SONET networks
Tips & Best Practices
-
Use the tool for planning and provisioning in telecommunications and data center networks
-
Consider the conversion as an approximate guideline due to SONET overhead variations
-
Apply these conversions when integrating modern digital rates with legacy optical infrastructure
Limitations
-
Converted values are approximate as STS3c (payload) includes framing and overhead affecting usable payload
-
Conversion does not factor in error correction or protocol layer overhead affecting throughput
-
High precision may be reduced due to network framing beyond nominal payload rates
Frequently Asked Questions
-
What does terabyte/second (SI def.) represent?
-
It is a data transfer rate unit representing one terabyte (10^12 bytes) moved each second, equal to 8 terabits per second.
-
What is the STS3c (payload) unit used for?
-
STS3c (payload) represents a SONET payload container used to carry high-bandwidth signals at roughly 155 Mbps over optical transport networks.
-
Why might the conversion values be approximate?
-
Because STS3c (payload) accounts for SONET framing and overhead, actual usable payload is slightly lower and varies with network protocols.
Key Terminology
-
Terabyte/second (SI def.)
-
A unit of data transfer rate equal to 10^12 bytes per second, or 8 terabits per second.
-
STS3c (payload)
-
A concatenated Synchronous Transport Signal level-3 payload container used in SONET delivering about 155.52 Mbps line rate, with usable payload slightly less.
