Definition: Synchronous optical networking (SONET) and Synchronous Digital Hierarchy (SDH), are two closely related multiplexing protocols for transferring multiple digital bit streams using lasers or light-emitting diodes (LEDs) over the same optical fiber.
The method was developed to replace the Plesiochronous Digital Hierarchy (PDH) system for transporting larger amounts of telephone calls and data traffic over the same fiber wire without synchronization problems.
SONET and SDH are based on circuit mode communication, meaning that each connection achieves a constant bit rate and delay.
For example, SDH or SONET may be utilized to allow several Internet Service Providers to share the same optical fiber, without being affected by each other's traffic load, and without being able to temporarily borrow free capacity from each other.
Only certain integer multiples of 64 kbit/s are possible bit rates.
