As the fiber is fragile, the fiber used in various environments must be processed into the fiber with the corresponding mechanical properties in order to prevent the fiber from external damage in the laying, installation, use, maintenance to ensure the smooth network. And now extensive use of outdoo

Single-mode fiber specifications are divided into two categories, one for ITU-T G.65X series and the other IEC60793-2-50. The communication industry requires a variety of single-mode fiber jumpers, and jumper types are often determined by the diversity of single-mode fiber. In general, there are 19

For a long time, fiber network system uses two fibers to complete duplex communication, one for transmitting signals and the other for receiving signals. However, single-fiber bidirectional technology breaks the traditional pattern. For network managers, this technology is an ideal solution to addre

1. Optical modem must be placed firmly, pay attention to ventilation, moisture, do not fall.2. In order to ensure the normal use, do not close the Optical modem power.3. Do not arbitrarily plug the power cable on the Optical modem, do not bend twisted fiber.4. In case of failure please try to turn o

The overhead cable is a cable used to hang on the poles and is usually used in conjunction with hanging wires. We know that the transmission performance of the cable is highly susceptible to tension, bending radius and side pressure, so the need for extra attention when laying overhead cable. This t

IntroductionThe fiber amplifier is an essential component of transmission applications such as metropolitan area networks. Its biggest feature is that it can directly amplify the optical signal without going through the process of optical-electrical-optical conversion. It is often used in wavelength

IntroductionThe SONET / SDH transport network defines a set of rates and formats for transmitting optical signals over optical fibers, often referred to as optical synchronous digital transmission networks, often used as backbone networks for telecommunication networks. With the development of optic

Optical attenuator is a passive optical device, mainly used to reduce the optical power of the optical signal to prevent the optical receiver from reaching the optical power beyond the load range caused by signal distortion; there is a situation in the multi-wavelength channel fiber System, the need

Fiber to the home (FTTH) to the home access network based on passive optical network technology (PON, passive optical network) is a point to multipoint network structure, that is, the use of optical splitter center signal to multiple end users. Optical splitter has two different distributions in the
