[Installation process]
1 Download the sofa butler installation file to U disk â†’ 2 TV installation applet â†’ 3 applet to open U disk file â†’ 4 Complete the installation

ã€Stepsã€‘

1. Baidu search for "sofa manager" into the sofa network, download the sofa butler package; or directly click the link (http://app.shafa.com/shafa.apk) to download the sofa butler package.

Copy the downloaded apk installation package to the U disk.

Method one: install through the cool open application circle applet

1, open Skyworth 55S9D TV to find - cool open application circle - click to enter.

2, in the cool open application circle - open the search.

3, in the search box, enter "XCX" - find the [small program] application, and install

4, open the applet application after the installation is complete.

5, enter the password - the password is "111111".

6, After the password is input correctly, the sofa butler package can be automatically identified in the U disk.

After installing the sofa butler, massive applications for you to download

If the above three types are installed via a USB flash drive, if you cannot read the USB flash drive, you are advised to format the USB flash drive in FAT32 format first (if there are other contents in the USB flash drive, export it and format it first) or try another U disk.

OTDR

Optical time-domain reflectometer (English name: optical time-domain reflectometer, OTDR) is an instrument that understands the uniformity, defect, fracture, and coupling of the optical fiber through the analysis of the measurement curve. It is made according to the principle of light backscattering and Fresnel reverse. It uses the backscattered light generated when light propagates in the optical fiber to obtain attenuation information. It can be used to measure optical fiber attenuation, connector loss, fiber fault location and understanding The loss distribution of the optical fiber along the length, etc., is an indispensable tool in the construction, maintenance and monitoring of the optical cable.

The optical time domain reflectometer will inject a series of optical bursts into the optical fiber for inspection. The method of inspection is to receive the optical signal from the same side of the incident wave, because the incident signal will be scattered and reflected back when it encounters a medium with a different refractive index. The intensity of the reflected light signal will be measured and is a function of time, so it can be converted into the length of the optical fiber.
The optical time domain reflectometer can be used to measure the length and attenuation of the optical fiber, including the fusion splice and transition of the optical fiber. It can also be used to measure the interruption point when the fiber is broken.
