The compact and efficient fiber laser replaces the industrial application of Nd:YAG lasers and has new applications in telecommunications. Lasers that use fiber optics as resonant cavities have entered the industrial arena and are beginning to replace larger, more cumbersome devices. In a typical fiber laser, the core of a single mode fiber incorporates erbium or ytterbium. A group of laser diodes, usually arranged in a tree-like shape, as a pump into the fiber, through which the laser of the...
Recently, a joint research team of several organizations has developed an innovative method that can print very 3D on the top of a fiber with a diameter of only 125 microns (about the width of a human hair). Subtle but highly complex structure. It is reported that this new technology is not only considered to be one of the most accurate methods for printing complex 3D structures on optical fibers, but also much cheaper than traditional methods, resulting in a large number of biosensors, optical...
Although current seismographs can accurately pick up slight tremors, their distance is relatively short. However, now, Stanford University research shows that a wide range of seismic detection networks can already exist at our feet: fiber-optic cables that carry high-speed Internet. Since the fiber acts by bounces the optical signal on a cable that is transparent like a glass plate, it is possible to measure the small interference of the signal. This technology, called Distributed Acoustic...
Media information: Raid5 server consisting of 16 fiber optic disks Fault description: In the customer raid server, two hard disks are dropped, causing the server to crash and the raid server data cannot be read. Data recovery process: After testing by Dash's senior raid data recovery engineer, it was found that both hard drives dropped bad sectors, causing the raid to crash. After that, the bad track hard disk is mirrored, and then analyzed and calculated under the RAID data recovery...
What is a fiber optic transceiver? A fiber optic transceiver is an Ethernet transmission medium conversion unit that interchanges short-distance twisted pair electrical signals with long-distance optical signals, and is also referred to as a photoelectric converter in many places. Optical transceivers are typically used in real-world network environments where Ethernet cables cannot be covered and must use fiber to extend the transmission distance, and are typically located in the access layer...

A 23-page new application guide published by Cisco and Corning Cable Systems covers best practices for deploying fiber optic infrastructure to Cisco's Nexus 6000 series data center switches. "As the speed of data centers now increases from 10 Gbps to 40 Gbps, and gradually increases to 100 Gbps, different optical technologies and cabling infrastructure are required." The guide noted in the introduction. "When designing a network system, it is important to plan the wiring...

OVUM's latest forecast report * stated that the optical fiber network market in Asia Pacific in 2016 was only $ 6.4 billion, because this overheated market is going through a cooling period. However, independent telecommunications analysts warned that although the Asia-Pacific market had a 4% compound annual growth rate (CAGR) between 2010 and 2016, this could not be compared with the astonishing 25% growth rate reached between 2005 and 2010. OVUM data shows that the Asia-Pacific market...
At present, outdoor optical cables for core networks and access networks for communications have a relatively mature structure and a laying method suitable for China's national conditions. At the same time, after the development in recent years, the indoor optical cable also has a relatively mature structure and has sufficient production capacity. However, this section of the optical cable line entering the home of the communication network is partly outdoors and partly indoors, which puts...

The basic working principle of fiber optic gyroscope The resonant interference gyro uses a coherent light source, but the requirements for the coherent characteristics of the light source are greatly reduced, so that a general commercial DFB device can be used as a laser light source. The principle of the resonant interference gyro is shown in Figure 1. The transmission ring resonator structure is used in the figure, and the required output is obtained by mutual interference between the...
Fiber optic gyro concept Fiber optic gyro is a very important angular rate sensor. It has the advantages of long life, fast start-up, high accuracy, low power consumption, wide dynamic range, etc. It plays an extremely critical role in the fields of aerospace, weapon navigation, etc. At present, fiber optic gyros mainly use two schemes: interferometric fiber optic gyro (IFOG) and resonant fiber optic gyro (RFOG). Interferometric fiber optic gyros are relatively mature. In order to improve the...
The working principle of fiber optic gyroscope The basic working principle of fiber optic gyro comes from the Sagnac effect. The Sagnac effect is a universal correlation effect that interrupts propagating light with respect to a closed-loop optical path rotating in inertial space, that is, two beams of light with the same characteristics emitted from the same light source in the same closed optical path are transmitted in opposite directions to each other and finally converge To the same...
