The article will then conclude by informing you on where you can find more information on ventilation ducting and spiral ducting.Different types of ducting including air conditioningAs mentioned previously there are many different types ducting out there on the market, it is only after you have a brief understand of the different types of ducting that you can be sure that you have made the right choice.
Some examples of the different types of ducting and their uses include:Slip system, spiral pipe and fittings – the main uses are heating, ventilation ducting, removal of chemicals Dwayne Haskins Jersey , fumes.Clip system, easy to install duct – main uses: dust extracting, saw dust, wood shaving removal, chemicals and fumes.Plastic system Da'Ron Payne Jersey , flat channel duct – main uses: kitchen extraction, bathroom extraction, tumbles dryer ventilation.Square system, rectangular ducting – main uses: heating, ventilation ducting Landon Collins Jersey , air conditioning, air movement.Air conditioning - the conclusionAs you can see there are many different types of ducting systems including ventilation ducting systems which are split into four different categories based on their functions and uses.
If you would still like some more information on any of these different products then this can be found by entering the keywords ‘air conditioning’ into an internet search engine. This search will allow you to scroll through a vast array of products that are currently out there on the market. Be sure to take your time with your search as this is the best way to ensure that you have made a thorough and educated decision on the product that is best suited to you. If you follow of the information above then you will be one step closer to choosing the best ventilation system to match you and your needs.
In a power-splitting PON, an optical power splitter is the passive device in the outside plant that physically connects to the CO with a feeder fiber. It also connects to a number of ONUs via a series of distribution fibers. In the past few years, significant improvements in reliability, cost per port Alex Smith Jersey , insertion loss, and splitting-ratio nonuniformity, have been demonstrated with planar lightwave circuit (PLC)-based splitters. Central to the splitter is a PLC chip comprising of optical waveguides fabricated on a planar substrate, typically made of silicon or quartz, to form a cascade of Y-branches. For a 1 脳 splitter Sean Taylor Jersey , one side of the PLC chip is aligned to a fiber whereas the opposite side is aligned to an array of PON is typically N = 16 and N = 325, but with an increasing demand of up to N = 64, thereby making the alignment of the fiber array to the PLC chip more challenging. Compared to fused biconical-taper-based splitters, PLC technology allows for chip-size devices with the potential of integrating multiple functions, e.g. WDM coupler, onto a single clip. It also enables a more uniform loss over a wide operating range of wavelengths from 1250 nm to 1625 nm Cheap Washington Redskins Hats , and operaton of a wide range of temeratures from -40℃ to + 80℃. Figure 3.2 illustrates the measured insertion losses from samples of 1脳32 optical splitter approved by AT&T Labs for use in the Project Lightspeed FTTH trial, showing uniform loss over a wide wavelength range.
Aside from uniform loss, the insertion loss of PLC splitters is another important parameter in network implementations that will influence system performance and the overall coast per drop. Lower insertion loss PLC slitters will extend the reach and number of customers that can be accommodated within the same PON, yielding higher revenue per PON for service providers. Aside of the theoretical splitting loss attributed to the division of optical power at the input port equally into N output ports, and given by the fromula:
Theoretical splitting loss (dB) = 10 脳 log10(1N)
A PLC splitter suffers from excess insertion loss from fiber array alignment to the PLC chip Cheap Washington Redskins T-Shirts , fiber array uniformity caused by pitch and depth inaccuracies in the v-grooves of fiber array block that holds the fiber array, splitting ratio uniformity caused by imperfections in the PLC chip due to manufacturing, inherent chip material loss, and inherent chip material loss, and connector loss. The targeted areas for improvement of insertion loss in PLC splitters have been in reducing connector losses Cheap Washington Redskins Hoodie , and improving fiber array and splitting ration-nonuniformity. The connector loss can be improved from 0.5 dB trough using high quality ferrules and an excellent polishing method. With advances in manufacturing process of the fiber array block and PLC chip, insertion losses from fiber array nonuniformity and splitting-ratio nouniformity can be reduced from 0.7 dB to 0.4 dB and 1.8 dB to 1.0 dB, respectively. Collectively, the excess insertion losses of PLC splitters are currently 1 – 1.5 dB above the ideal theoretical splitting loss with a nonuniformity within 2 dB over the specified range of operating wavelengths from 1250 nm to 1625 nm.
