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 have
continued to widely deploy high-speed DWDM (Dense Wavelength Division Multiplexing) systems. DWDM's tighter
wavelength spacing fit more channels onto a single fiber, but cost more to implement and operate. This is why DWDM are
not 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. DWDM
Mux/Demux, DWDM SFP+ optics, EDFA (Erbium-Doped Fiber Amplifier) as well as other optical components used in
DWDM system are available in Fiberstore with very competitive prices and absolute high performance.

Related Components in This Solution
Icon Instructions Role
Transmitter
Transmitters take an electrical input and converts it to an optical output from a
laser diode or LED.
Receiver
Receivers use semiconductor detectors (photodiodes or photodetectors) to convert
optical signals to electrical signals.
Isolator
Fiber optic isolator can transmit light in a certain direction while blocking light in
the opposite direction.
Dense Wavelength
Division Multiplexing
DWDM networks need multiplexer/demultiplexer (MUX/DEMUX) modules to
combine and split wavelength channels at standard ITU grid.Dense Wavelength
Division De-
Multiplexing
Coupler/Splitter
Coupler/Splitters are branching devices used to combine or distribute optical
signals to single or multiple locations for processing.
Tunable Bandpass Filter
Tunable filter can be used as a much smaller alternative to physically large
switched 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 Switch
Optical switch is a switch that enables signals in optical fibers or integrated optical
circuits (IOCs) to be selectively switched from one circuit to another.
EDFA (Erbium-Doped
Fiber Amplifier)
EDFA is an optical repeater device that is used to boost the intensity of optical
signals being carried through a fiber optic communications system.
FBG (Fiber Bragg
Grating)
Fiber Bragg grating can therefore be used as an inline optical filter to block certain
wavelengths, or as a wavelength-specific reflector.

DWDM
Transceivers
DWDM Transceivers are self-contained components that can both transmit
and receive. Fiberstore highly recommends you the fixed channel DWDM
SFP+ modules for C-band (ready stock), as well as the tunable XFPs.
Optical Isolators
Fiberstore offers a range of in-line type and beam expanded isolator,
narrowband and broadband free-space optical isolators (Faraday isolators)
including 1310/1550nm/1064nm high power polarization maintaining isolator
and high power Polarization insensitive circulator. We also can supply a
custom isolator service that can combine the best features of our entire
isolator products.
DWDM
MUX/DEMUX
Fiberstore provides a series of DWDM MUX/DEMUX modules with as more
as 96 channels (50GHz, 100GHz, or 200GHz spaced) in simplex or duplex
configurations. All the DWDM modules are available with three types of
packaging: ABS Pigtailed Box, Rack Chassis and LGX Cassette.
Couplers/Splitters
Fiberstore provides both PLC splitters and FBT couplers with a variety of
specification options.
Fiber Bandpass
Filters
Fiberstore offers Fiber Bandpass Filter (BPF) based on the Thin Film Filter
(TFF) technology with low insertion loss, low polarization dependence, high
isolation and excellent environmental stability.
Optical
Circulators
Fiberstore provides both polarization insensitive and polarization maintaining
circulators. These circulators feature with high isolation, low insertion loss,
and excellent environmental stability etc. Additionally, customized orders are
available.
Optical Switches
Fiberstore provides four series of optical switches, including opto-mechanical
optical switch, MEMS optical switch, solid-state optical switch, rackmount &
benchtop optical switch. Switch type includes 1x1, 1x2, 1x4, 1x8, 2x2 as well
as dual 1x2 and 2x2 bypass for single mode fibers, multi-mode fibers, non-
latching and latching are available. And 1xN rackmount and benchtop optical
switches are also available which are ideal for high-volume manufacturing
production testing.
DWDM EDFA
Fiberstore DWDM EDFA is an easy-to-use and cost-efficient solution for
DWMD fiber optic link amplification which operates at the transmission side
of the link. It is designed to amplify aggregated optic input power for reach
extension. Using dual-stage pump laser design and internal Gain Flattening
Filter (GFF) to compensate the erbium fiber gain variation, it features high
input power, low noise.
