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.

1.About Us  Â
3.Customized Service Â
1.Design   ( drawing for qute and design files require )Â
Start with your CAD / PDF / 3D / Picture Drawing is the quickest and easiest way for made custom enclosures . let our engineers will according your requirement to design for you . 2Cut holes :
 Our standard cut tolerance is ±0.2 mm but tighter tolerances can be met when required. Extrusion is available as bars or cut-to-length (marked, deburred, and ready for installation).We can drill holes through any of our housings to meet your specific requirements.Our CNC processing center enables us to carry out difficult machining work to tight tolerances. From a nominal dimension (both size and location) our CNC equipment tolerance is ±0.1mm. We are capable of holding ±0.2 mm with high process capability on dimensions of size (hole diameter).  3.Finish treatment Â
