What does OC24 represent in SONET?

OC24 is an Optical Carrier level 24 rate in SONET networks, equal to 24 times the base OC-1 rate, indicating a high-capacity optical fiber channel.

Why convert OC24 to STS3c (payload)?

Converting OC24 to STS3c (payload) helps in understanding how a large SONET channel maps into multiple smaller payload units for provisioning and traffic management.

Can I use this conversion for newer optical transport technologies?

No, this conversion applies specifically within SONET transport standards and may not be valid for newer technologies like OTN or Ethernet-based transport.

What Is This Tool?

This converter transforms data transfer values from OC24, a high-capacity SONET rate, into multiple STS3c (payload) units, representing contiguous SONET transport channels. It is designed specifically for telecommunications professionals working with SONET optical networks.

How to Use This Tool?

Enter the OC24 value you want to convert.
Select STS3c (payload) as the target unit.
Click the convert button to see the equivalent STS3c (payload) value.
Use the result for provisioning or network design purposes.

Key Features

Converts OC24 values to STS3c (payload) units based on SONET standards.
Supports network planning and traffic management for legacy SONET systems.
Provides a clear way to map aggregate fiber channel capacity into individual transport payloads.
Browser-based and straightforward for quick calculations.

Examples

1 OC24 equals approximately 8.28 STS3c (payload).
3 OC24 converts to about 24.83 STS3c (payload) based on multiplication.
Use these examples to estimate the number of STS3c payload channels from a given OC24 capacity.

Common Use Cases

Backbone trunk links in carrier SONET networks aggregating lower-rate circuits.
High-capacity WAN circuits connecting data centers in legacy SONET deployments.
Traffic grooming or interfacing between SONET equipment and higher-layer networks.
Enterprise leased-line services requiring roughly 155 Mbps circuits.
Transporting client signals like ATM or frame relay within SONET payloads.

Tips & Best Practices

Understand that STS3c (payload) reflects usable payload slightly below the gross line rate.
Use conversion results for SONET network planning and not for unrelated optical technologies.
Check compatibility when integrating with newer network technologies beyond SONET.
Apply this converter to assist in traffic grooming and accurate circuit provisioning.

Limitations

STS3c (payload) capacity is slightly less than gross OC-3 line rate due to framing overhead.
Conversion is specific to SONET and may not match rates in newer optical transport formats like OTN or Ethernet.
Results represent approximate usable payload, not exact gross rates.
