Some users are easily confused about the transmission distances of all kinds of network cables we use in daily life while knowing that information is important for selecting the proper cable, so an overall conclusion following will be necessary and greatly helpful.1. The network cableCat5, Cat6 are

Common fiber nouns1) AttenuationAttenuation: light’s energy loss transmitting in single-mode fiber 1310nm 0.4~0.6dB/km 1550nm 0.2~0.3dB/km plastic multi-mode fiber 300dB/km. 2) DispersionDispersion: light pulse’s march for a distance along the fiber causes the wider bandwidth. It is the main factor

We know that optical cable owns advantages of high bandwidth, low loss, and other advantages, and its price is getting lower and lower, which is now widely used in a variety of distributions. However, since most of the fibers are made of quartz glass, they are very fragile with poor bending resistan

In the PDS system, optical cable in the trunk (vertical) wiring usually contains 2-144 fibers or even more to transmit the data to multiple users. Tight-buffered trunk optical cable with characteristics of durability and easy termination is the common cable type for trunk (vertical) wiring, which is

Tight-buffered trunk optical cable is composed of multiple sets of fibers, usually used in the trunk (vertical) wiring subsystem to connect devices and telecommunications. Now there are a variety of optional tight-buffered trunk optical cables on the market, applicable to different application envir

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

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
