What does USB stand for and what is its primary use?

USB stands for Universal Serial Bus and is used for data communication and power supply between host devices and peripherals such as storage devices and input gadgets.

What is OC768 and where is it commonly used?

OC768 is an optical carrier rate with a high line speed used in fiber-optic backbone links, telecom core transport, and long-haul and metro DWDM systems.

Why is the conversion between USB and OC768 approximate?

Because USB speeds vary by generation and OC768 represents a fixed high-capacity line rate, the conversion is approximate and does not reflect real-world factors like overhead or throughput limitations.

How to Convert from USB to OC768?

Easily convert data transfer rates from USB, the common device interface, to OC768, a high-capacity optical carrier rate used in backbone networks. Understand the relationship between consumer-level data transfer and telecom core transport speeds.
