On May 12th, for technology companies, submarine fiber optic cable is its lifeline. Especially in the era when cloud services are prevalent, it takes a little more time to load the server. Microsoft, which emphasizes action first, certainly understands this, so they just planned to invest heavily in the laying of three submarine fiber-optic cables. According to reports, Microsoft plans to invest in three submarine fiber-optic cables laid out by Aqua Comms, Hibernia and New Cross Pacific Cable...
Optical fiber transmission has the advantages of transmission frequency bandwidth, large communication capacity, low loss, no electromagnetic interference, small optical cable diameter, light weight, and rich source of raw materials. Therefore, it is becoming a new transmission medium. Losses occur when light is transmitted through an optical fiber. This loss is mainly caused by the transmission loss of the optical fiber itself and the splice loss at the fiber joint. Once the optical fiber...
Fiber optic Common fiber types include stepped and gradient multimode fiber and single mode fiber. The following factors must be considered when selecting fiber: (1) Numerical aperture NA of optical fiber From the viewpoint of improving the coupling efficiency between the light source and the optical fiber, a large NA is required, but the larger the NA, the more severe the mode dispersion of the optical fiber and the smaller the capacity for transmitting information. However, for most optical...

With the development of technology, the requirements for fiber loss are becoming more and more strict. The 10G network requires the total fiber link loss to be controlled below 2.6dB, while the 10M and 100M network fiber loss requirements are relatively loose, which is relatively This makes it almost easy to implement a fiber link in the original network. However, if the rate is increased to 1G and 10G, the original minimum loss may not be suitable for new applications. Fiber testing is...

1. The impact of lightning The armor components of the fiber optic cable are all metal conductors. If the power line is short-circuited or the lightning strikes the metal parts, a strong current will be generated to damage the cable line equipment. In serious cases, there may even be casualties. 2. The insulation of the optical cable line is not good. If the communication optical cable line is not insulated, the operation strength of the optical cable will be greatly reduced due to stress...
The choice of fiber optic cable is not simple. Compared with twisted pair cable and coaxial cable, it is not only complicated in structure, but also has a wide variety of materials. In addition to the existing technical parameters, there are many potential factors (materials, production processes, equipment, etc.), slightly Inadvertently, don't say that the service life of the second or third year is difficult to protect, that is, the technical parameters of several years may not be up to...
10-Gbit Ethernet LAN technology is increasingly used in enterprises, which brings new challenges and opportunities to optical transmission network (OTN) suppliers. Similarly, for companies that serve businesses, governments, and other large organizations, the transparent transmission of 10-Gbit Ethernet signals is becoming a key competitive factor. From the perspective of the end customer, the OTN should be a seamless extension of the existing 10-Gbit Ethernet LAN infrastructure without having...

To repair aging infrastructure and monitor existing bridges, dams, and other large buildings, distributed fiber optic sensors require a new type of light source to monitor the stress and temperature changes experienced by the building. However, this common fiber optic sensor, based on the nonlinear optical phenomenon of stimulated Brillouin scattering (SBS), is limited by the insurmountable spatial range and resolution. At present, researchers in Spain and Switzerland have solved these...
