Frequently Asked Questions
-
What is Ethernet (fast)?
-
Ethernet (fast) refers to the IEEE 802.3 family providing a nominal data rate of 100 megabits per second, commonly used in local area networking with twisted-pair or fiber connections.
-
What does Virtual Tributary 1 (signal) represent?
-
Virtual Tributary 1 (signal) is a logical sub-channel within SONET/SDH networks that carries lower-rate digital signals independently inside a higher-rate synchronous frame.
-
Why would I convert Ethernet (fast) to Virtual Tributary 1 (signal)?
-
Conversion helps map Ethernet streams into SONET/SDH networks, enabling aggregation, grooming, and interfacing with optical transport systems.
-
Are there hardware requirements for this conversion?
-
Yes, practical use requires equipment compatible with both Ethernet (fast) and SONET/SDH protocols to perform accurate signal encapsulation.
