- 不能， 光纖需要用紅光筆(或紅光光源)，大紅300至1000元不等 。 使用時(shí)將光纖接入紅光筆(或紅光光源).斷點(diǎn)處會(huì)用紅色光溢出. 另外比較專業(yè)的人士可以使用OTDR(光時(shí)域反射儀).這個(gè)是專業(yè)儀器，不適用于個(gè)人. 是通光斷點(diǎn)處的反射信息進(jìn)行反饋信息，然后計(jì)算斷點(diǎn)位置.

- 尋線器不能尋光纖。只能尋找能感應(yīng)導(dǎo)電的介質(zhì)，如銅，鐵等，光纖是玻璃纖維，不導(dǎo)電，所以不能用尋線器尋找。 工作原理: 尋信號(hào)震蕩發(fā)聲器發(fā)出的聲音信號(hào)通過(guò)RJ45/RJ11通用接口接入目標(biāo)線纜的端口上，至使目標(biāo)線纜回路周圍產(chǎn)生一環(huán)繞的聲音信號(hào)場(chǎng)，用高靈敏度感應(yīng)式尋線器很快在回路沿途和未端識(shí)別它發(fā)出信號(hào)場(chǎng)，從而找到這條目的線纜。 尋線器利用了感應(yīng)尋線原理來(lái)尋找線纜，所以它不需打開(kāi)線纜的絕緣層，在線纜外皮上的不同部位找到信號(hào)?？梢栽诰€纜群束中，地毯下、裝飾墻內(nèi)、天花上迅速找到所需電纜以及它的斷點(diǎn)的大概位置。

- 1.OpticalGasDetectionOpenPath(line-of–sight)GasDetectionemployingelectro-optical"spectralfinger-print"analysisoftheatmosphereusestheDifferentialOpticalAbsorptionSpectros... 1. Optical Gas Detection Open Path (line-of –sight) Gas Detection employing electro-optical "spectral finger-print" analysis of the atmosphere uses the Differential Optical Absorption Spectroscopy (DOAS) technique in a unique (patented) method. The use of discriminative UV and IR narrow band filtered sensors enables the detection， identification and concentration determination of Flammable & Explosive gases migrating in the atmosphere， at concentrations well below their explosive levels. The specific systems developed for detection of flammable or toxic gases employ a flash or filament light source， which is in communication with a detector that responds to the attenuation in the light intensity caused by the presence of the gas. This line of Optical Gas Detection Systems known as SafEye has been successfully introduced into the High Risk/High Value markets. 2. Optical Flame Detection Flame Detection employing electro-optical analysis of the electromagnetic radiation emitted by flames in the Ultraviolet and Infrared spectral bands. The patented spectral analysis of the Flames radiation signals includes frequency and time domain analysis， cross correlations and ratios between the various sensor inputs. Unique background radiation analysis enhances the flame detection accuracy in a cluttered environment that contains various emitting sources like: direct solar radiation， heaters and burners， light projectors， high voltage sparks and welding radiation， extreme temperature conditions. This line of Optical Flame Detectors named SharpEye was developed and introduced into the safety and high risk/high value fire protection markets. The SharpEye series includes UV， UV/IR， Triple IR (IR3) and CCTV Optical Flame Detectors. 3. Explosion & Fire conditions Detection Explosion & Fire conditions can be detected very early by monitoring their environmental characteristics such as: changes in temperature and pressure caused by gaseous decomposition processes， radiation emitted during such processes， decomposition by-products that can be monitored at very low concentrations in air. Monitoring combustion products such as: CO2， CO， NOx， HC (unburned hydrocarbons)， etc.， at very low concentrations in air (at PPM levels) enables very early and reliable detection of these conditions. The SafEye line of Optical Gas Analysis Systems includes UV and IR specific models. 4. Military Explosion Detection and Suppression Systems SAFE line of military vehicle fire and explosion detection and suppression systems was developed by Spectrex Inc. in order to protect personnel from skin burns and pressure shock. The systems suppress gas or vapor explosions in less than 150 milliseconds， with a speed of response of less than 3 milliseconds. Suppression is activated in less than 5 milliseconds to discharge and disperse the agent， thus providing a uniform extinguishing concentration. The systems have been incorporated successfully in thousands of military vehicles worldwide 展開(kāi)
