What Is This Tool?
This converter allows users to translate data transfer rates from Virtual Tributary 2 (VT2) payload units, used in legacy SONET/SDH networks, into Ethernet (fast) units, which are part of modern 100 Mbps Ethernet networking standards. It helps assess and plan network capacity across these technologies.
How to Use This Tool?
-
Enter the value in Virtual Tributary 2 (payload) units you want to convert
-
Select the 'Virtual Tributary 2 (payload)' as the source unit

Common Use Cases
-
Translating data rates from legacy SONET/SDH TDM circuits to Ethernet for network integration
-
Planning network capacity when migrating between SONET/SDH infrastructure and Ethernet LAN/WAN
-
Engineering telecommunication networks that combine optical fibre transport with Ethernet systems
Tips & Best Practices
-
Understand the fixed payload rate of Virtual Tributary 2 at 2.048 Mb/s when converting
-
Use this conversion as part of broader network planning and integration efforts
-
Remember that protocol adaptation is needed beyond rate conversion for interoperability
Limitations
-
Virtual Tributary 2 payload has a fixed rate of 2.048 Mb/s limiting granularity compared to Ethernet’s 100 Mbps
-
Conversion only reflects data rate differences, not protocol compatibility or overhead
-
Additional encapsulation or adaptation is required for practical use between these technologies
Frequently Asked Questions
-
What is Virtual Tributary 2 (payload)?
-
It is a SONET/SDH virtual tributary container sized to carry a 2.048 Mb/s PDH/E1 channel used to transport lower-rate TDM signals over optical networks.
-
What does Ethernet (fast) mean?
-
Fast Ethernet refers to IEEE 802.3 standards supporting a nominal data rate of 100 Mbps commonly used for local-area networking.
-
Does this conversion imply protocol compatibility?
-
No, the conversion only translates data rates; additional protocol adaptation or encapsulation is needed for actual interoperability.
