AON vs PON Networks: Which One to Choose for FTTH Systems

Fiber to the home (FTTH) is a system which installs optical fiber from a central point directly to individual buildings such as residences and apartments. The deployment of FTTH has come a long way before subscribers adopt optical fibers instead of copper lines to achieve broadband Internet access. There are two basic paths to deploy high-speed FTTH network: active optical network (AON) and passive optical network (PON). Then AON vs PON networks: what's their difference? What Is Passive Optic...

Introduction to Fiber Optic Closure

In order to meet the stringent protection requirements of fiber optic splices, fiber optic splice closures, also called fiber splicing closures, are usually used to provide space for fiber optic cables to be spliced together. The fiber optic closure connects and stores optical fibers safely either in the outside plant or indoor buildings. It can provide protection for the fiber joint and the fiber cables, since they have excellent mechanical strength and strong out shell, which ensures the joint...

Fiber Optic Transmission Multiplexing Techniques

In fiber optic communication, multiplexing is considered to be the principal means for the expansion of existing fiber network engineering. Since optical data can be carried by employing different physical dimensions, such as time, frequency, space, polarity, etc., different multiplexing techniques are possible to be used in increasing the data carrying capacity of a single optical fiber. At present some multiplexing techniques are already used in the progress of optical innovation, and some app...

What Is a Fiber Optic Splitter?

The fiber optic splitter is also referred to as optical splitter, which is an integrated waveguide optical power distribution device. It plays an important role in passive optical network (EPON, GPON, BPON, FTTX, FTTH and so on) by allowing a single PON interface to be shared among many subscribers. To achieve this, it is designed to split an incident light beam into two or more light beams and couple the light beams to the branch distribution as an optical fiber tandem device, which has the fun...

CWDM vs DWDM: What’s the Difference?

When dealing with OTN (Optical Transport Network), there are two main types of Wavelength Division Multiplexing (WDM) systems: Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM). As two modern WDM technologies, they are both used for increasing the bandwidth of fiber by combining optical signals of different wavelengths on one strand of fiber. But CWDM vs DWDM, what are their differences? WDM, CWDM and DWDM Wiki To better understand the differenc...
