An Optical Time Domain Reflectometer (OTDR) is an optoelectronic instrument which used to calculate the fiber cable link distance, loss and reflection of each event, in addition to calculating the total link length, total link loss, ORL, fiber attenuation and locate events and trouble shooting.

We are OTDR manufacturer to supply customers all kinds of OTDRs, standard OTDRs or customized OTDRs.  Many options for customers choose, like dynamic range from high to low, multi-wavelength singlemode 1310/1550nm, multimode 850/1300nm, on-line testing 1625nm or 1650nm. Multi functions in one OTDR device are free for customers like built in Optical Light Source (OLS), Optical Power Meter (OPM), Visual Fault Locator (VFL), Insertion Loss Testing, Smart Event Mapper, Head Lamp, RJ45 Cable Testing, Connector End-face Inspection, Touch Screen etc.
