fibre and copper for data transmission network In terms of the physical infrastructure mediums the main choice is between a copper or fibre based system. So, which is the best to install? Like all good, simple questions, the route to the answer is a little more complicated. Historically, fibre was used in the backbone and […]

Benefits of Pre-Terminated Solutions (Pre-terminated assemblies) – 2
Benefits of Pre-Terminated Solutions – 2 Commercial Office Pre-terminated Assemblies The completion of the handover of a project is critical, mainly due to the fact that the lease deadline of the end user client’s existing facilities, have to be met to avoid the costly penalty of having to extend their previous lease by a further […]
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 […]
4G Subscribers reached 497 million by Year end 2004, growth outpaced 3G.
March 11, 2015: GSA, the Global mobile Suppliers Association, has underlined the accelerating pace of development of LTE around the world by confirming that LTE subscriptions are growing faster than any other mobile communications system technology, and by a substantial margin. Referring to newly-released data provided by Ovum Ltd, GSA calculated that 4G LTE subscription […]

DWDM Disadvantages and DWDM Advantages
DWDM Advantages and DWDM Disadvantages Breif introduction about DWDM Fiber with great capacity of bandwidth for long haul back bone data transmission. and DWDM, which is short for Dense Wavelength Division Multiplexing. is one of the dominant technology used to utilize the application of fiber cable. It means multiplex a group of wavelengths into and […]
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 Fusion Splicer
How to choose a fiber optic fusion splicer (welding machine, or splicing machine) Background Since optical fiber start for business application in mid 1980s, its about 30 years now. people right now adequate to the benefits of it. and it is widely used worldwide, no matter in developed country or developing country, however, it is […]
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. […]
