摘要： Proposed is a technique for detecting a damaged VCSEL in a short time and at low cost. It shows the light emission spectrum of a multi-mode VCSEL before an ESD damage, and the light emission spectrum which shows several peaks corresponding to the structure of the active layer (MQW) and the upper and lower reflectors (DBR) is obtained. On the other hand, when the VCSEL which has an ESD damage has a damage in the active layer, the light emission spectrum which shows fewer peaks than the original number of peaks is obtained. Accordingly, the light spectrum analyzer analyzes the light emission spectrum, and it is determined that ESD damage has occurred when the number of peaks is equal to or smaller than a predetermined number, e.g., two peaks.

摘要： A location judgment unit (411) judges whether an installation location of a base station (10) is in a first area corresponding to a service area of a first network operator. A frequency determination unit (412) determines, by using a first procedure, a radio frequency for use in wireless communication between the base station (10) and a mobile station (30) when the installation location of the base station (10) is in the first area, and determines the radio frequency of the base station (10) by using a second procedure different from the first procedure when the installation location of the base station (10) is outside the first area. The second procedure includes: receiving information on a frequency available in the installation location of the base station (10) from a frequency management system (50) that manages a frequency of a second area including the installation location of the base station (10); and determining a radio frequency of the base station (10) based on the frequency information.
