What Is This Tool?
This converter helps you translate data transfer measurements from Ethernet (fast), which operates at 100 Mbps, to Virtual Tributary 2 (signal), a SONET/SDH sub-rate format carrying a 2.048 Mbps payload. It supports telecommunications and network engineering tasks involving legacy and modern systems.
How to Use This Tool?

Examples
-
Converting 1 Ethernet (fast) equals approximately 43.4 Virtual Tributary 2 (signal).
-
Converting 2 Ethernet (fast) results in around 86.8 Virtual Tributary 2 (signal).
Common Use Cases
-
Enabling interoperation between 100 Mbps Ethernet networks and SONET transport systems.
-
Grooming lower-rate PDH channels within SONET multiplexers or digital cross-connects.
-
Planning telecom network capacity involving E1 and PDH services.
-
Integrating legacy telecom infrastructures with modern LAN technologies.
Tips & Best Practices
-
Use the conversion mainly for capacity planning and provisioning purposes.
-
Be aware that the conversion is conceptual due to differing physical and link-layer mechanisms.
-
Confirm compatibility when integrating Ethernet networks with SONET/SDH systems.
-
Consider that overhead and protocol framing differences are not included in this conversion.
Limitations
-
The conversion is based on nominal data rates without accounting for overhead.
-
It does not reflect protocol-specific framing or physical layer differences.
-
Direct real-time substitution between units is not possible; use for planning only.
Frequently Asked Questions
-
What does Ethernet (fast) refer to?
-
Ethernet (fast) is the family of IEEE 802.3 standards offering 100 Mbps data rates, typically implemented as 100BASE-TX over twisted-pair copper or 100BASE-FX over fiber.
-
What is Virtual Tributary 2 (signal)?
-
Virtual Tributary 2 (VT2) is a SONET/SDH sub-rate signal that carries a 2.048 Mbps payload, allowing the multiplexing of lower-rate PDH circuits into higher-rate containers.
-
Why convert from Ethernet (fast) to Virtual Tributary 2 (signal)?
-
This conversion enables integration and capacity planning between Ethernet LANs and SONET backbone networks transporting E1/PDH channels.
