Multiplexer Knowledge

A matrix switcher for WDM signals is larger and more complex than that used for a TDM signal as shown in Figure 1…

Wave Division Multiplexing (WDM) enables multiple data streams of varying wavelengths (“colors”) to become combined right into a single fiber, significantly enhancing the overall capacity from the fiber.

Multiplexing and multiple accessing are similar concepts that provide solutions for complex electronic communication…

what is the difference between SDN and DWDM? See here for the quick answer.

PDH, or Plesiochronous Digital Hierarchy, is a conventional technology used to transport large quantities of data over digital transport media, such as fiber-optic and microwave radio systems…

In a WDM network the commonly used frequency grid is either 50 or 100 GHz, which will have a major effect on which from the above-described approaches can be applied…

The difference between analog TV frequency and digital TV frequency is that the digital signals are compressed into “multiplexes”…

Multiplexing is a form of data transmission in which one communication channel carries several transmissions at the same time…

The range of frequencies is limited, but the number of devices using the system fluctuates. One way to separate the different data streams is each one have its’ own frequency…

Fiber optic modems receive incoming optical signals over fiber optic cables and convert them back to their original electronic form for full duplex transmission…

Fiber optic modems are the ideal when working with large amounts of data. Fiber optics allows data to be transferred quickly and efficiently. There are common types of fiber optic modem introduction. Click here to see if interested.

Fiber optic modems are often used in data communication systems to bridge long distances at high data rates…

Choosing the best fiber-optic modem depends on a few factors, including availability, usability and cost. A modem connects an electronic device such as a computer to a network or the Internet…

High-speed Internet has become somewhat of a necessity these days. For the Internet aficionado the ability to utilize the web at lightning fast speeds is of utmost importance.

Activation is the process of associating a specific modem with a valid cable Internet account to enable it to access the network. Two common activation methods are the self-install kit and manual activation…

CWDM is definitely an optical technology for transmitting as much as 16 channels, each in a separate wavelength or color, within the same fiber strand…

DWDM is core technology in an optical transport network. The concepts of DWDM are similar to those for CWDM. However, DWDM spaces the wavelengths more tightly, yielding up to 160 channels…

In SDH, overhead is the data that is transferred across the interface between a telecommunications system, such as a server and a client or user on a network…

When service is interrupted, you must reset the modem and the wireless router to re-establish the connection. Following is the step…
