What does OC1 represent in data transfer?

OC1 is the base optical transmission rate in SONET networks, defined as 51.84 megabits per second and associated with an STS-1 electrical signal.

Why convert OC1 to Virtual Tributary 1 (payload)?

Converting OC1 to the VT1 payload standardizes lower-rate channel transport within SONET/SDH networks, enabling efficient switching and grooming of lower-bit-rate signals.

Can this conversion be used outside SONET/SDH networks?

No, the conversion assumes SONET framing and may not be applicable to other data transport systems.
