Home / Advantages of Fiber Optic Communication PDH
Advantages include high bandwidth usage, low power consumption and lower investment and operating/maintenance costs. general Optical Fiber communication system, advantages of optical fiber communications. Optical fiber wave guides- Introduction, Ray theory t ansmission, Total Interna ERS: Attenuation, Absorption, Scattering and Bending losses, Core and Cladding losses. This article briefly discusses the following stages of optical fiber communication: i) Plesiochronous Digital Hierarchy (PDH) ii) Synchronous Digital Hierarchy (SDH) iii) Wavelength Division Multiplexing (WDM) iv) Elastic Optical Networks (EONs) v) Space Division Multiplexing (SDM). Unlike PDH, SDH is synchronous, meaning that all the network elements operate on a common clock. With PDH technology, there is a possibility that one user's speech reaches another user with delays due to unsynchronized transmission times.
