A fiber fused coupler is one of the most popular passive components for wavelength multi/demultiplexing or branching/combining of optical signal. They are used to split optical signals between two fibers, or to combine optical signals from two fibers into one fiber. Fused couplers do suffer from some disadvantage. Multimode fused couplers are mode dependent. Single fused couplers only transmit one mode, so they do not suffer from mode dependency.

It does this by taking power from a power supply and increasing the output to match the (relatively low-power) input signal. This process invariably introduces some noise and distortion into the signal; and the process cannot be 100% efficient at increasing the gain without loss — amplifiers inherently will lose some energy in the form of heat. The ideal amplifier can be described as "a straight wire with gain," as the output would be identical to the input, just greater.

Gastroenterology involves the overall understanding of the normal gastrointestinal organs action. Gastroenterologists have to understand motility - the movement of material through the stomach and intestine, the digestion and absorption of nutrients and the function of the liver.


There are many other diagnosis instruments used for medicine such as EMR and esd instruments, urology instruments equipped with endoscopic equipments like hemostasis clip, endoscopic accessories and so on.

Reducer is a pipe fitting component which reduces the flow size from larger to smaller by reducing size of pipe. Usually there are two types of reducers are available. One is concentric reducer which is like cone shaped with gradual decreasing around the pipe but in this case accumulation of air may possible and it results in cavitation. Other one is eccentric reducer which is having one edge parallel to connecting pipe due to which air accumulation is not possible.

Plumbers often use PEX in home plumbing systems thanks to its many advantages. This type of plastic water pipe is useful for both hot and cold water applications, and is the favorite pipe found carrying freshwater in kitchens and bathrooms. PEX is very flexible, so it fits into most spaces and is inexpensive and easy to work with. It comes in different colors, making it easy for plumbers to identify hot and cold lines for future work. They do need to have support, however, because of their flexibility.

Wear Pipelines Layer is a seamless steel pipe, and the inner layer is alumina ceramics. Ceramic liner layer hardness is up HV1100-1400, which is equivalent to tungsten carbide cobalt. The wear resistance performance is 20 times higher than carbon steel tubes. Alumina Ceramic Sheet Wear-resistant Tube can resist industrial wear problem mainly by a few millimeters thick corundum inner layer, which is much better than alloy steel pipe and cast tube resisting by both composition,organization and thickness.

Many of the hoses in your vehicle, like your radiator hoses which carry coolant to keep your engine at the proper operating temperature, are made of rubber. Overtime, these hoses will crack and can cause leaks. It's important to get these components replaced when excessive cracking occurs, to keep from costly engine repairs. Other hoses in your vehicle connect to fuel lines, air conditioning, power steering and your braking system.

Fire doors are commonly designed to include a closing mechanism. Usually fitted at the top of a door, these spring-loaded or hydraulic mechanisms force the door closed, preventing fire and smoke from passing from one area to another.


Just like fire doors, many Security Doors and Hospital Doors are also uses Wooden Doors or even Steel Doors to ensure better security.

Since the design of these conveyors is simplistic, many advancements have been made to allow roller conveyors to keep up with industry trends. The biggest innovation is the drive or live roller conveyor, where each roller is connected to a motor via a belt/chain/shaft to increase controllability. This equalizes the rate with which materials move down the pathway, and also allows these conveyors to have limited use in reverse, i.e.
