Benefits of Pre-Terminated Solutions – 1

Benefits of Pre-Terminated Solutions – 1 Pre-terminated solutions for cabling systems have been around since the beginning of computing, well before the inception of Structured Cabling. Early IBM System 36 and 38 computers used to be connected to its peripherals by way of factory terminated twin-ax assemblies, very similar to the ones still used today […]

WDM-PON

WDM-PON Technology

WDM-PON Technology A typical wavelength division multiplexing PON (WDM-PON) architecture is shown in Figure 4-1. The wavelength division MUX/DEMUX is employed in the ODN. In the example in Figure 4-1, array waveguide gratings (AWGs) are used to MUX and DEMUX wavelengths to or from ONUs. Signal transmission in WDM-PON is similar to that in the […]

Backbone The cabling used to connect entrance facilities, crossconnects, telecommunications closets, and equipment rooms. The backbone may consist of either interbuilding and/or intrabuilding cabling. Backreflection The loosely-used term covers optical return loss (ORL) for spans, reflectance for components, and Fresnel reflectance. Backscatter coefficient The ratio of the optical pulse power (not energy) at the OTDR […]

HOW To choose fiber optic cable

HOW To choose the right fiber optic cable for your fiber optic network? Background of fibe roptic nework The fundamental difference between a fiber optic communication system and other types is that signals are transmitted as light. Conventional electronic communication relies on electrons passing through cables. Microwave communication relies on microwaves travelling through open space. […]

Is it possible to think of something without knowing a word to describe it ? According to some studies, humans understand the concept of numbers and counting before knowing the words for those numbers. Perhaps that means that this month’s blog will be easier for everyone to understand, since I’ve found that it’s hard to […]
