Dense Wavelength Division Multiplexing (DWDM)

Solution

The continued emergence of the Internet and the insatiable demand for real-time interaction with multimedia applications

has continued to fuel the demand for increased bandwidth. To satisfy this demands, telecommunication providers havecontinued to widely deploy high-speed DWDM (Dense Wavelength Division Multiplexing) systems. DWDM's tighterwavelength spacing fit more channels onto a single fiber, but cost more to implement and operate. This is why DWDM arenot as popular as we expected over the past few years.

Fiberstore offers a comprehensive solution for DWDM system which helps you slove the problem of high cost. DWDMMux/Demux, DWDM SFP+ optics, EDFA (Erbium-Doped Fiber Amplifier) as well as other optical components used inDWDM system are available in Fiberstore with very competitive prices and absolute high performance.

Transmitter Transmitters take an electrical input and converts it to an optical output from alaser diode or LED.

Receiver Receivers use semiconductor detectors (photodiodes or photodetectors) to convertoptical signals to electrical signals.

Isolator Fiber optic isolator can transmit light in a certain direction while blocking light inthe opposite direction.

Division De-Multiplexing

Coupler/Splitter Coupler/Splitters are branching devices used to combine or distribute opticalsignals to single or multiple locations for processing.

Tunable Bandpass Filter Tunable filter can be used as a much smaller alternative to physically largeswitched filter banks and cavity tuned filters.

Fiber Optic Circulator Fiber optic circulator is a passive optical component that can be used to achieve bi-directional transmission over a single fiber in DWDM networks.

Optical SwitchOptical switch is a switch that enables signals in optical fibers or integrated opticalcircuits (IOCs) to be selectively switched from one circuit to another.

EDFA (Erbium-DopedFiber Amplifier)

EDFA is an optical repeater device that is used to boost the intensity of opticalsignals being carried through a fiber optic communications system.

FBG (Fiber BraggGrating)

Fiber Bragg grating can therefore be used as an inline optical filter to block certainwavelengths, or as a wavelength-specific reflector.
