Advantages and disadvantages of SONET

SONET is commonly transmit data at speed between 155 megabits per second and 2.5 gigabits per second. To the build these high bandwidth data streams, SONET multiplexer together channels having bandwidth as low as 64 kilo bits per second into data frames sent at fixed intervals. So now let us check out the advantages and disadvantages of SONET to know more details about SONET.

Advantages of SONET :
  • Reduced cost
  • It offer network survivability features
  • It is compatible with legacy and future network
  • Very high efficiency
  • Allows transportation of all  forms of traffic
  • Standard optical interference
  • De-multiplexing is easy
  • Remote operation capabilities. It is remotely provisioned, tested, inventoried, customized and reconfigured
  • Can we used in SONET networks for fast restoral and protection
  • Out of band management system
Disadvantages of SONET :
  • No interoperable standard
  • Tributary services require SONET mux services
  • Low cost effective for low channel numbers.
  • SONET/SDH network management system not well equipped to handle DWDM and management
  • Bandwidth efficiency is problem at higher capacity
  • More overhead is required
