What Is This Tool?
This unit converter allows you to convert data transfer rates from Ethernet (fast), a 100 Mbps Ethernet standard, to Virtual Tributary 2 (VT2) payloads used in SONET/SDH networks for carrying lower-rate PDH/E1 channels.
How to Use This Tool?
-
Enter the data transfer value in Ethernet (fast) units into the input field.
-
Select Ethernet (fast) as the source unit and Virtual Tributary 2 (payload) as the target unit.
-
Click the convert button to get the equivalent VT2 payload value.
-
Use the result to assist in network planning and protocol conversion tasks.
Key Features
-
Converts Ethernet (fast) data rates to Virtual Tributary 2 (payload) units quickly.
-
Supports network engineers and service providers working with hybrid SONET/SDH and Ethernet infrastructures.
-
Browser-based and requires no installation for immediate use.
-
Provides precise conversion based on the standard conversion rate of 1 Ethernet (fast) = 48.828125 VT2 payloads.
Examples
-
1 Ethernet (fast) is equal to 48.828125 Virtual Tributary 2 (payload).
-
2 Ethernet (fast) correspond to 97.65625 Virtual Tributary 2 (payload).
Common Use Cases
-
Integrating 100 Mbps Ethernet LAN traffic into SONET/SDH networks using VT2 containers.
-
Facilitating legacy circuit emulation for PDH/E1 channels over optical backbones.
-
Enabling granular multiplexing and grooming of Ethernet data within high-rate synchronous optical networks.
Tips & Best Practices
-
Verify that your network architecture supports both Ethernet (fast) and SONET/SDH standards before conversion.
-
Use this tool as part of planning when bridging legacy TDM services with modern Ethernet LANs.
-
Consider the physical media and link behavior of Ethernet (fast) in network deployment scenarios.
-
Remember the conversion is based on nominal data rates and does not include overhead or inefficiencies.
Limitations
-
Conversion reflects nominal data rates without accounting for protocol overhead or inefficiencies.
-
Multiple VT2 payload units are required to match the throughput of one Ethernet (fast) signal.
-
Primarily applicable for hybrid networks combining legacy TDM and modern Ethernet technologies.
