Fiber optic attenuator is a device to reduce the power level of an optical signal, either in free space or in an optical fiber. Things You Should Know About Fiber Optic Attenuators Why Fiber Optic Attenuators Are Needed? Most people believe bigger signal power level is better, right? Beginners in [ Continue reading…]
What Is 25 Gigabit Ethernet & Why Is It in Demand? Though the migration from 10 GbE (Gigabit Ethernet) to 40/100 GbE is widely recognized as the Ethernet speed upgrade path and greatly satisfies the increasing demands for higher bandwidth and speed, people still keep pursuing a better solution to [ Continue reading…]
In most industries, every couple of years, some new technologies and products would come out to replace the old ones to satisfy the growing demands of people. That’s also what happened in the telecommunication industry. In the past decades, different transmission technologies had come into being to satisfy the growing [ Continue reading…]
Multiplexing of fiber optic communication carrier for optical wave. Fiber optic communication multiplexing technique is mainly divided into three categories: optical multiplexed, optical signal multiplexing and subcarrier multiplexing with (SCM). Optical wave multiplexing wavelength division multiplexing (WDM) and space division multiplexing (SDM), the optical signal multiplexing comprises time-division multiplexing (TDM) and frequency division multiplexing with a [ Continue reading…]
In fiber optic communication, multiplexing is considered to be the principal means for the expansion of the capacity of existing fiber network engineering. Multiplexing techniques include time division multiplexing TDM (Time Division Multiplexing) technology, MIMOs SDM (Space Division Multiplexing) technology, WDM (Wavelength Division Multiplexing) technology and frequency division multiplexing FDM with [ Continue reading…]
Definition Fiber optic splice closure is usually used with outdoor fiber optic cables, provides space for the outdoor fiber optic cables to be spliced together. The fiber optic splice closures and the fiber trays inside will protect the spliced fiber and the joint parts of the outdoor fiber cables. Generally the [ Continue reading…]
Defination Passive optical network-PON is a network that brings optical fiber singal to the end of users by the point-to-multipoint(P2MP) fiber to the premises in which optical splitters are used to “broadcast” signals to many users. A PON consists of an optical line terminal (OLT) at the service provider’s central [ Continue reading…]
Network cable is connected from a network device (such as a computer) to another network device, it is the basic component of the network. In our common LAN, network cable is used with a variety of types. Under normal circumstances,generally a typical local area network is not use a variety of different [ Continue reading…]
1) Cat1 Lan/ Network Cable: The highest frequency of this cable is 750 KHZ, used for alarm systerm, or only suit for voice transmission(this kind of standard is mainly used in telephone cable before the eighty’s ). It’s the different from the data transmission. 2) Cat2 Lan/ Network Cable [ Continue reading…]
Optical device module fiber testers automation instrument and system provider recently released PLC integrated automatic fiber tools fiber tester system. Compared with the early release of PLC system, the system is more comprehensive, including both the insertion loss, PDL, channel, uniformity index, at the same time, the system adopts the unique “reception” [ Continue reading…]
