Fiber optic media are any network transmission media that generally use glass, or plastic fiber in some special cases, to transmit network data in the form of light pulses. Within the last decade, optical fiber has become an increasingly popular type of network transmission media as the need for higher bandwidth and longer spans continues. […]
Passive Optical Network
Passive Optical Network Overview
A Passive Optical Network (PON) is illustrated schematically in the figure below. A feeder fiber from the Central Office (CO) runs to a Remote Node (RN), which houses a passive optical power splitterkombiner. From there, around 32 fibers branch out to the subscribers. If these fibers extend all the way to the homes (H), as […]
Four Requirements Promote the Development of PLC Passive Devices
The demand of PLC passive optical devices are increasing for information transmission, thus promoting the development of PLC technology, mainly from the four major areas requirements listed below. 1. Pressure From Backbone Network Communication Broadband subscribers are growing with growth rate of 20-30% per year, average traffic growth per user per year up to 20-30%. […]
Optical Passive Categories Introduction
Optical passive devices is an important part of the communication device, but also the other optical components indispensable application areas. There are mainly four categories of Optical Passive. (A) Active Fiber Optic Cable Connector Fiber optic cable connector is connected to two active optical fiber to form a continuous optical path and can be repeated […]
