Optični časovni odsevni reflektor (OTDR)

OTDR (optical time-domain reflectometer) 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 backscattering and Fresnel reverse of light. 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 Loss distribution along the length of the fiber, etc. It is an indispensable tool in the construction, maintenance and monitoring of optical cables. OTDR has the advantages of short test time, fast test speed, and high test accuracy.

The working principle of OTDR:

Optical cable testing is an important technical means for the construction, maintenance and repair of optical cables. At present, the most effective method is to use OTDR (Optical Time Domain Reflectometer) to monitor the optical fiber connection and measure and evaluate the connection loss. This method is intuitive, reliable, and it can print the fiber backscatter signal curve. In addition, while monitoring, the actual transmission distance from the office to each joint can be measured relatively accurately. Maintenance is very necessary for accurately detecting faults and effectively handling them. At the same time, maintenance personnel are required to master the performance of the instrument, skilled operation skills and accurate judgment of the signal curve characteristics.

The OTDR test is performed by sending light pulses to the optical fiber, and then receiving the returned information at the OTDR port. When the optical pulses are transmitted in the optical fiber, due to the characteristics of the optical fiber itself, connectors, joints, bending or other similar events, the optical pulses will be scattered and reflected. Part of the scattered and reflected will be returned to the OTDR. The useful information returned is measured by the OTDR detector and they are used as time or curve segments at different locations in the fiber. From sending the signal back to the signal, then determining the glass material, you can calculate the distance in the time required for the speed of light.

Lomoveishiy - Finska

Potrebovali sem jih za povezavo računalnika v tretjem nadstropju, da sem imel dostop do interneta v tej sobi, ponudnik internetnih storitev pa je njihov modem namestil samo v prvem nadstropju. Ko ste spustili optične kable, priključite vse kable v te medijske pretvornike na obeh straneh in povezava je prišla takoj. Bilo je veliko lažje, kot sem mislil!

Raymond - ZDA

Odlične izkušnje - enote so delovale naravnost iz škatle - potrebovali smo le še priključitev kablov in končali smo. Všeč mi je tudi možnost, da omogočim jumbo okvirje, čeprav trenutno nimamo potrebe po tej funkciji, je super, da imamo to možnost.
