High Channel Density
Carry dozens of independent optical channels over the same fiber infrastructure.
Increase fiber capacity by combining multiple closely spaced optical channels over existing single-mode fiber.

A DWDM Mux Demux is a passive wavelength-division multiplexing device that combines multiple closely spaced optical channels onto a common fiber and separates them again at the receiving end.
DWDM channels follow the frequency grid defined by ITU-T G.694.1, allowing significantly more wavelength channels within the C-band than CWDM.

The essential value at a glance, with the complete technical context available below.
Carry dozens of independent optical channels over the same fiber infrastructure.
Expand network capacity without installing additional fiber.
The Mux/Demux itself requires no power supply, software or active management.
The passive device is protocol and data-rate transparent. Actual service rates depend on the DWDM transceivers or coherent interfaces used in the network.
Increase fiber capacity between data centers or network facilities where fiber resources are limited.
Aggregate multiple optical services between POPs, aggregation sites and network facilities.
Build high-capacity point-to-point, ring and multi-site optical transport networks.
Transmit multiple independent services over existing dark-fiber infrastructure instead of deploying additional fibers.
DWDM can be integrated with suitable transceivers, optical amplifiers, dispersion management where required, and other transport equipment for extended-distance applications.

A widely used choice for passive DWDM networks, offering a good balance between channel density, optical performance and system simplicity.
Provides twice the nominal channel density of a 100GHz grid and is suitable when more wavelengths are required within the available optical spectrum.
Important: The DWDM Mux/Demux channel frequency must match the optical transmitter frequency.
Switch between the documented deployment patterns to understand component placement and traffic flow.
The most straightforward DWDM architecture uses separate fibers for each transmission direction.

The same DWDM channels can be used in both directions because transmission and reception use separate fibers.
Save Fiber with Bidirectional Transmission
Single-fiber DWDM carries traffic in both directions over one fiber.

The two ends use complementary wavelength arrangements and must be designed as a matched pair.
Extend Optical Reach When the Link Budget Requires It
For longer or higher-loss links, DWDM can be combined with optical amplifiers.

Amplifier type, location and gain must be designed according to:
Channel power
Number of wavelengths
Fiber attenuation
Mux/Demux loss
Receiver requirements
OSNR
Total system link budget
DWDM with OADM
Selected DWDM channels can be added or dropped at intermediate network locations while other channels continue through the fiber.

This architecture is suitable for metro, access and multi-site optical networks.
Detailed engineering context is preserved without interrupting the main selection journey.
Maximize the Capacity of Existing Fiber
Carry dozens of independent optical channels over the same fiber infrastructure.
Expand network capacity without installing additional fiber.
The Mux/Demux itself requires no power supply, software or active management.
The passive device is protocol and data-rate transparent. Actual service rates depend on the DWDM transceivers or coherent interfaces used in the network.
C-band DWDM systems can be designed with optical amplifiers such as EDFAs when required by the link budget and network architecture.
More Than the Mux/Demux
A complete DWDM network can include:
Fixed or tunable DWDM optical modules matched to the required ITU channels.
Add or drop selected DWDM wavelengths at intermediate network locations.
Optical amplification for suitable C-band DWDM network architectures.
A lower-channel-density alternative for applications that do not require the capacity of DWDM.
Every DWDM Channel Verified Before Shipment
DWDM uses narrow channel spacing, making accurate spectral performance especially important.
