5Km Range 5mw Fiber Checker Fault Finder High Quality 5mW VFL Optical Fiber Cable Tester, Fiber Optic Visual Fault Finder

The cable core is composed of a plurality of mutually insulated wires or conductors, and the communication line is provided with a sealing sheath on the outside. Some are also equipped with an outer sheath outside the sheath. There are various laying methods such as overhead, direct burial, pipeline and underwater. According to the structure, it is divided into symmetrical, coaxial and integrated cables; according to functions, it is divided into field and permanent cables (underground and submarine cables). The communication cable has a wider transmission frequency band, a larger communication capacity, and less external interference, but it is not easy to repair. It can transmit telephone calls, telegrams, data and images, etc. Mainly used to transmit audio, 150kHZ and below analog signals and 2048kbit/s and below digital signals. Under certain conditions, it can also be used to transmit digital signals above 2048kbit/s. It is suitable for overhead or pipeline laying lines in urban, suburban and local areas, and can also be directly buried. Product name: Communication cable Model: HYA, HYAC, HYAT, HYA53, HYAT53, HYV, HYA23, HYAT23, HYA22, HYAT76. HYA type urban communication cable adopts full chromatographic insulation and aluminum-plastic composite sheath (that is, the longitudinal shielding aluminum tape of the cable is bonded to the sheath to form a sealing sheath), which has the characteristics of superior electrical performance and convenient construction.

2, method of use:

1, from the end of the pen on the pen body rotation, the prepared two No. 5 batteries into thebatteryto thepenpen tail,tail(bottomnote!) A pen seat, negative alignment;

2, the pen pen body and tail connection installed,open thedust cap,according toacontrol switch,aredlightobservationinterface,while indicatinglight;(note the eyes not to the optical interface, so as not to damage the eyes);

3, according to a control switch, a lightpulseisobserved,indicatinga luminous anda light pulse (pulse frequency in 0.5-2HZ);

4, press the switch once, the source is shut off, nolight outputat the same time,the emittingtube is extinguished; (switch mode: continuous pulsed closed cycle modecontinuous)

5, detection of the tested fiber into the optical interface, at the same time according to thecontrol switch, select the output light mode (continuous or pulsed);

6, after use, the dustproof cap, do not use a long time, remove the battery to avoid batterydamage, decay, light.

3, maintenance and matters needing attention:

1, the laser is harmful, especially to protect the eyes, laser, avoid direct eye laser;

2, in general, the higher the temperature is, the shorter life of laser, when used to avoid high temperature working environment;

3, the laser optical fiber head clean;

4, do not use the source, please dust cap to avoid dust falling;

5, do not use the should be removed;
