What Is This Tool?
This converter helps you transform data transfer measurements from STS48 (signal), a high-rate SONET transport signal, into STS3c (payload), a concatenated SONET payload container. It facilitates understanding how many smaller payload channels fit within a larger optical signal.
How to Use This Tool?
-
Enter the value in STS48 (signal) you want to convert
-
Select STS48 (signal) as the input unit and STS3c (payload) as the output unit
-
Click convert to see how many STS3c payload containers correspond to the given STS48 signal
Key Features
-
Converts between STS48 (signal) and STS3c (payload) units used in optical networking
-
Browser-based tool for quick and easy calculations
-
Provides clear conversion rates and examples for accurate bandwidth planning
Examples
-
1 STS48 (signal) converts to approximately 16.55 STS3c (payload)
-
2 STS48 (signal) converts to approximately 33.10 STS3c (payload)
Common Use Cases
-
Carrier long-haul and metro backbone transport planning
-
Designing high-capacity interconnects between core routers or data centers
-
Mapping and grooming multiple lower-rate circuits into larger transport channels
Tips & Best Practices
-
Consider SONET framing and overhead which reduce actual payload capacity
-
Verify network equipment compatibility when subdividing or aggregating signals
-
Use conversion results to aid in detailed bandwidth planning and traffic grooming
Limitations
-
Actual payload throughput is slightly less due to SONET framing and overhead bytes
-
Conversion assumes ideal signal conditions without accounting for network impairments
-
Signal integrity and equipment compatibility must be considered in real applications
Frequently Asked Questions
-
What does STS48 (signal) represent?
-
STS48 (signal) is a high-capacity SONET signal level equivalent to OC-48, used for carrying multiplexed digital payloads at a transport rate of about 2.488 Gbit/s over optical fiber.
-
What is STS3c (payload) used for?
-
STS3c (payload) provides a contiguous SONET payload channel with a gross line rate of 155.52 Mbps, commonly carrying Ethernet or IP signals in optical transport networks.
-
Why convert STS48 (signal) to STS3c (payload)?
-
Converting helps understand how many smaller STS3c payload containers can be multiplexed within a larger STS48 signal, aiding in bandwidth planning and client signal mapping.
