What are the common types of fiber optic cables?

Just like snowflakes, although the basic shapes are similar, there are no two snowflakes with exactly the same shape in the real world. Scientists have discovered tens of thousands of snowflakes, and optical cables of different structures, viewed from the cross section, are also blooming. Beautiful snowflakes, each type of snowflake (section) has a unique aesthetic. According to different structural shapes, optical cables are divided into layered type, skeleton type, bundled tube type and ribbon type.Stranded type: A cable in which loose or tight fibers are twisted around a central strength member. Tight or loose optical fibers refer to optical fibers wearing protective coats. The protective coat materials mainly include polypropylene, nylon-12, polyester elastomer, fluorine-46, fiber-reinforced plastics, directional stretched polymers, […]

Looking at these instructions, are you using the optical module right?

With the development of optical communication technology, the application of optical modules is becoming more and more common. How to use the optical module correctly, let’s take a look at the instructions for using the optical module! See if you use it right? Anti-static measuresWhen installing an optical module, anti-static measures must be taken whether indoors or outdoors, and you must ensure that you touch the optical module with your hands while wearing anti-static gloves or an anti-static wristband. Pick and place operationIt is strictly forbidden to touch the golden finger of the optical module when handling the optical module, and it must be handled with care to prevent the optical module from being pressed and bumped. Disassembly methodWhen removing […]

What is an SFP optical module?

The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic device includes two parts: transmitting and receiving. Optical modules are mainly used in optical communication, data centers and other places. So, what exactly is an optical module? What is the use of the optical module? Next, let’s follow the editor of Feichang Technology to learn more about it! Simply put, the function of the optical module is photoelectric conversion. The transmitting end converts the electrical signal into an optical signal, and after transmission through the optical fiber, the receiving end converts the optical signal into an electrical signal. In addition, optical modules can be classified according to packaging and can be divided into: The XFP […]

Reasons and judgment of the failure of the combiner box to communicate

In the daily operation and maintenance of photovoltaic power plants, the combiner box often fails to communicate normally due to various problems, resulting in the untimely update of the photovoltaic array status, resulting in power generation losses and hidden dangers. Therefore, it is very important to promptly and quickly troubleshoot the communication problems of the combiner box. Communication line short circuit The combiner box of a photovoltaic power station is usually 16~20 combiner boxes as a photovoltaic array. When the communication line is short-circuited, all the combiner boxes in the entire array cannot communicate, and the RS485 communication voltage of the combiner box module is zero. Solution: Disconnect all the communication lines of the combiner boxes in the array and […]

Sensing Cable

Sensing fiber optic cables can be used not only for data transmission, but also to measure temperature, strain rate and acoustic signals in harsh environments. AP Sensing’s Distributed Temperature Sensor (DTS) and Distributed Fiber Optic Sonic/Vibration Sensing (DAS & DVS) solutions enable efficient monitoring of critical infrastructure and buildings such as railway and road tunnels, pipelines, bus ducts and parking lots .Optical cables generally have three components: core, coating, and cladding. The cladding core has a different index of refraction, which is the speed at which light travels through the material. By minimizing the normal critical angle, maximum total internal reflection is achieved, so light can travel for kilometers with minimal attenuation.Our sensor cables (sensing fiber optic cables) are completely […]
