What is OC12 in telecommunications?

OC12 is a SONET optical carrier rate carrying 12 STS-1 channels, used for high-capacity fiber-optic transport with a nominal rate of 622.08 Mbps.

What does T0 (B8ZS payload) represent?

T0 (B8ZS payload) is a raw T-carrier bitstream encoded with Bipolar with 8-Zero Substitution, preserving time-division multiplexed data for transport or analysis.

Why convert from OC12 to T0 (B8ZS payload)?

Conversion enables interfacing between SONET optical links and legacy or packet-based T-carrier systems while preserving B8ZS-encoded payloads.

How to Convert from OC12 to T0 (B8ZS payload)?
