		In telecommunications, insertion loss is the decrease in transmitted signal power resulting from the insertion of a device in a transmission line or optical fiber.
		Insertion loss is defined as a ratio of the signal level in a test configuration without the filter installed (V1) to the signal level with the filter installed (V2).
		Common-mode insertion loss is measured by connecting the line and neutral terminals together and using the test configuration of figure 1.

		A: Yes, the two most important parameters that describe the performance of an RF switch are the insertion loss in the closed state and the isolation in the open state.
		Insertion loss is the attenuation between input and output ports of the switch when the switch is on.
		In this application, such an increase in insertion loss is not material, since the principal concern is about the signal levels relative to one another.

	Definition: insertion loss
		The loss resulting from the insertion of a device in a transmission line, expressed as the reciprocal of the ratio of the signal power delivered to that part of the line following the device to the signal power delivered to that same part before insertion.
		Note: Insertion loss is usually expressed in dB.
		In an optical fiber system, the total optical power loss caused by insertion of an optical component, such as a connector, splice, or coupler.

	Testing Splitter's & Directional Couplers
		The procedure for measuring the insertion loss of a directional coupler is illustrated in Figure 53.
		Losses caused by the resistance of the inner conductor vary with the cross sectional area of the conductor.
		Most of the loss, however, is frequency related, a condition called "skin effect." Skin effect describes the condition where, as the frequency of the signal increases, the signal is carried through the conductor further and further away from the center.

		Insertion loss also increases with frequency as the square root of the increase.
		The disadvantages of coax are that it has insertion loss, power limitations and increases system expenditures, Generally speaking, the greater the flexibility and the smaller the diameter of the coax, the higher the insertion loss.
		Finally, when a large diameter low loss coax is used as the main feedline, it is often difficult to connect the coax directly to the antenna.

		One of the fundamental considerations for all coupling applications is the capacitor’s insertion loss at the operating frequency.
		An insertion loss of several tenths of a dB is generally an acceptable criterion for most coupling applications.

	Measuring insertion loss of cavities
		Measuring Insertion Loss with Wattmeters Passband insertion loss is a primary specification of a wide variety of passive RF devices.
		It is not easy to accurately measure low values of insertion loss at high power using ordinary radio transmitters as signal sources and RF wattmeters, such as the Bird model 43 or similar.
		This Tech-aid explains why indirect insertion loss measurements made with a single wattmeter are prone to significant errors and describes a two-wattmeter method that is more likely to be in agreement with measurements made with laboratory-quality instruments.

	RF Splitters - Home tech Solutions
		RF Splitters are rated in two basic ways: The frequency range they are designed to handle, and the insertion loss incurred when a signal passes from the input to any of the outputs.
		This can cause variations of the insertion loss for each output as well as variations of loss at different frequencies, which is very hard to correct.

	Lightwave - Trends in DWDM multiplexers and their impact on network performance
		As was the case for the TFF, the serial process restricts the practical channel count due to size, accumulated insertion losses, and costs of the individual piece parts.
		Insertion loss is perhaps the most important and frequently specified mux parameter, because it impacts the reach of an optical signal.
		Although some vendors define insertion loss at the peak transmission within the passband, it is more meaningful to specify insertion loss at the minimum transmission within the passband, which typically occurs at the passband edges.

	Fibrepulse - Insertion Loss Testing
		Insertion loss refers to the loss of light, not so much in the cable assembly, but that loss caused due to the assembly's introduction.
		There may be very little light lost through the assembly itself, but the majority of losses related to optical cable assemblies relate to how well the fibres align with mating connectors when the assembly is introduced.
		Generally, an insertion loss of 0.50dB per connection is acceptable.

	Managing RF Signals in Test Systems
		Power losses primarily are a function of the resistive and impedance mismatch losses through a circuit path.
		For example, the insertion loss of a directional coupler might be rated at 0.1 dB maximum, but the insertion loss from the coupling of 10 dB of the power theoretically would be 0.46 dB.
		Understanding power losses and how to determine their magnitude are essential for estimating actual circuit performance, factoring the information into the stimulus levels applied to the DUT, and interpreting the results read back by test instrumentation.

		Insertion loss is defined as the difference in sound level at a receiver location with and without the presence of a noise barrier, assuming no change in the sound level of the source.
		For the purpose of determining barrier insertion loss, it is important to remember that microphone locations relative to the sound Source in the BEFORE and AFTER cases must be identical.

	Radome Transmission Loss and Antenna Pattern Degradation
		Radome transmission loss is the sum of the ordinary insertion loss of the antenna (radar) signal passing through the radome wall plus the scattering loss off the radome panel framework blocking (shadowing) the antenna aperture.
		The precise details of where this energy goes is dependent on the shadow length and radome transmission loss, the electronic signature of the framework and the positions and orientations of the framework members shadowing the reflector.
		In summary, the superior transmission loss performance of the symmetric orange peel random over the quasi-random unit is both a property of the shorter shadow length and smaller electronic signature.
