What is Fast Ethernet?

Fast Ethernet is a family of IEEE 802.3 standards delivering nominal data rates of 100 megabits per second typically over twisted-pair copper or fiber.

What does STS3c (payload) represent?

STS3c (payload) is a concatenated SONET payload container providing a single contiguous transport channel with a gross line rate of 155.52 Mbps, used for carrying high-bandwidth client signals.

Why convert Ethernet (fast) to STS3c (payload)?

To map 100 Mbps Fast Ethernet traffic into higher-bandwidth SONET containers, enabling backbone optical transport and leased-line services.

Common Use Cases

Mapping 100 Mbps Fast Ethernet signals into high-bandwidth SONET payloads for optical transport.
Integrating local-area network traffic into backbone optical links such as OC-3.
Supporting leased-line enterprise services requiring approximately 155 Mbps circuits.
Transporting client signals like ATM or frame relay within a single contiguous SONET payload.

Tips & Best Practices

Use this tool for telecommunications and network engineering scenarios involving SONET.
Ensure proper protocol adaptation when converting due to differences in Ethernet and SONET framing.
Consider the overhead bytes in STS3c payload as it slightly reduces usable capacity.
Verify network requirements for integrating LAN data into wide-area or backbone networks.

Limitations

STS3c payload rate includes overhead, so actual data throughput is slightly less than 155.52 Mbps.
Fast Ethernet is limited to 100 Mbps and this tool does not increase that physical rate.
Physical and framing differences between Ethernet and SONET require separate protocol adaptation.
