(a) Actual circuit; (b) AC equivalent circuit; (c) High-frequency equivalent circuit
Similar to the analysis of the capacitive feedback oscillator, the oscillation frequency of the oscillator can be approximated by the resonance frequency of the loop, namely 
Where L is the total inductance of the loop, as shown in Figure 4-9 
In fact, from the analysis of phase balance conditions, the oscillation frequency of the oscillator is expressed as 
Vibration conditions Engineering does not consider the influence of gie when calculating the feedback coefficient, the size of the feedback coefficient is 
According to the analysis of the vibration conditions, it can also be obtained that the gm at the time of vibration should meet
In daily life, iron-shell ONU is one of the common passive optical network equipment.
Generally speaking, the shell material of the ONU is plastic, which makes the overall body lighter and more resistant to corrosion.
However, in some cases we need to use iron to make the ONU shell. Why is it necessary to use iron, a heavy and non-corrosive material, to make the ONU shell? The answer is that in outdoor situations, the high temperature makes the whole body hot, and the plastic shell has poor heat dissipation, which often makes the whole body temperature too high. However, the normal operating temperature of the ONU must not be higher than 80 degrees. Under circumstances, iron as a material with very good thermal conductivity and heat dissipation is very suitable for use as an ONU shell. This is the advantage of iron-shell ONUs-suitable for outdoor installation, high temperature resistance, and protection of the body from high temperature damage .
But don`t choke food because of poor plastic heat dissipation. In most indoor situations or when the temperature is not high, ONUs with plastic shells are still the best choice. Based on their good corrosion resistance and lightweight body, people still often choose ONU in plastic case.
