Synchronous Optical Network (SONET) Transmission
PDF of this tutorial8. When Is a Separate SONET Layer Needed?
When assessing the need for SONET, certain parameters must be acknowledged. If any of the following are required, SONET is necessary:
- reliable transmission
- ultrafast protection mechanisms
- extensive monitoring
- fastest transmission speeds (10 Gbps)
- long-distance transmission (>120 km)
- multiplexing scalability (1.5 Mbps to 10 Gbps)
- global reach (optical amplifiers and regenerators)
- optical layer integration
