That’s also what happened in the telecommunication industry. In the past decades, different transmission technologies had come into being to satisfy the growing [ Continue reading…]
Fiber Optic Transmission Multiplexing Technique
No CommentsMultiplexing of fiber optic communication carrier for optical wave. Fiber optic communication multiplexing technique is mainly divided into three categories: optical multiplexed, optical signal multiplexing and subcarrier multiplexing with (SCM). Optical wave multiplexing wavelength division multiplexing (WDM) and space division multiplexing (SDM), the optical signal multiplexing comprises time-division multiplexing (TDM) and frequency division multiplexing with a [ Continue reading…]
Brief Analysis Optical Network Multiplexing
No CommentsIn fiber optic communication, multiplexing is considered to be the principal means for the expansion of the capacity of existing fiber network engineering. Multiplexing techniques include time division multiplexing TDM (Time Division Multiplexing) technology, MIMOs SDM (Space Division Multiplexing) technology, WDM (Wavelength Division Multiplexing) technology and frequency division multiplexing FDM with [ Continue reading…]
Fiber Optic Splice Closure introduction
No CommentsDefinition Fiber optic splice closure is usually used with outdoor fiber optic cables, provides space for the outdoor fiber optic cables to be spliced together. The fiber optic splice closures and the fiber trays inside will protect the spliced fiber and the joint parts of the outdoor fiber cables. Generally the [ Continue reading…]
Passive Optical Network introduction
No CommentsDefination Passive optical network-PON is a network that brings optical fiber singal to the end of users by the point-to-multipoint(P2MP) fiber to the premises in which optical splitters are used to “broadcast” signals to many users. A PON consists of an optical line terminal (OLT) at the service provider’s central [ Continue reading…]
Types of Network Cable
