The function of OTDR
An OTDR (Optical Time Domain Reflectometer) is used in fiber optics to measure the time and intensity of the light reflected on an optical fiber.
An OTDR can detect such light loss and pinpoint trouble areas, making repairs easy. The more quickly trouble areas are identified and addressed, the less your fiber optic network will suffer from data transfer problems. More to the point, it is used as a troubleshooting device to find faults, splices, and bends in fiber optic cables, with an eye toward identifying light loss. Light loss is especially important in fiber optic cables because it can interfere with the transmission of data.
The OTDR is not perfect, of course. Critics charge that it can produce inaccurate results if two trouble spots are very close together or if the pulse has a long travel length. Experts also urge training in order to interpret the data correctly. Another factor is the relatively high price for a device that might be used only sparingly.
Proponents, however, counter that being able to pinpoint and address light loss points is well worth the price, both for the OTDR device and for the training needed to operate and properly understand the data that that OTDR records.
Sopto provides SPT3302 OTDR with a special price. Competing with JDSU OTDR, SPT3302 with almost the same function but a cheaper price.You can contact to us for more about Optical Time Domain Reflectometer,Price,Product,Description.
The power meter , consists of two parts, the power sensor and the power indicator. The power sensor is also called the power meter probe, which converts the high-frequency signal into the electrical signals that can be detected directly through the power. The power indicator includes the signal amplification, signal transformation, and the displayer. The displayer shows the power value directly. It uses the cable to connect the power sensor and the power indicator. In order to adapt to the different frequencies, different power level and the needs of different transmission line structure, a power meter need a number of power meter probes with different function.

The price of optical cable connectors is related the market. But there are lots of factories whose technology is not mature, so the data will not be stable. Therefore, choosing a good manufacturer is the very important. If we blindly request low price, it will too late to cry in the construction and usage when there is a problem. SOPTO has four type of fiber optical fast connector: SC/UPC, SC/APC, FC/UPC and FC/APC. These products pass strict inspection before shipment and fully meet the industry standards. Welcome industry colleagues inquire the price information by phone.
The price of fiber optic cables depends on the types of fiber, the types of fiber cables, the amount of cable cores and the brands. Generally, in China, the price of the outdoor 4 cores single-mode fiber optic cable is about RMB3 per meter. And the more number of cores, the higher the price. Usually, if the price is below the RMB2 per meter, we do not recommend using it. It is not worth to save such little money as the signal servicer because if the signal attenuation is too strong, it will be useless to invest much more equipment.
