CCWDM MUX/DEMUX 4 or 8 Channel 1470 to 1610nm Dense WDM Transceiver
for Fiber Optic Networks Industrial Grade
Low-Profile Design: 1U Rack Space for Multi-Channel Deployment
The 4/8 Channel CCWDM MUX/DEMUX utilizes Thin-Film Filter (TFF)
technology and free-space cascading to multiplex/demultiplex
multiple optical channels. Its compact design allows deployment
within a standard 1U rack space, reducing volume by over 60%
compared to traditional CWDM modules. The plug-and-play modular
design eliminates the need for additional cooling equipment,
significantly simplifying installation.

Data Center Interconnect: Addressing Fiber Shortage under
High-Bandwidth Demands
In data center interconnect scenarios, the 4/8 Channel CCWDM
MUX/DEMUX multiplexes multiple wavelength channels onto a single
fiber, increasing transmission capacity by 4-8 times and
alleviating fiber resource constraints. For example, an 8-channel
model can simultaneously transmit eight 10Gbps signals, achieving a
total bandwidth of 80Gbps—ideal for high-speed data exchange
between server clusters. Its passive design eliminates
optical-electrical conversion losses, making it particularly
suitable for short-distance (≤40km) high-density connections.
Energy-Efficient Design: Over 50% Rack Space Savings
By integrating TFF filters and free-space optical paths, this
module consumes less than 1/10th the power of traditional DWDM
systems. For instance, an 8-channel model consumes only 0.5W per
unit, compared to over 5W for equivalent DWDM equipment with laser
cooling. In fully racked scenarios, space utilization improves by
50%, directly reducing data center cooling and power costs.
Low-Cost CCWDM MUX Solution
Ideal for budget-conscious enterprise network upgrades, with
per-channel costs at 1/3 of DWDM.
High-Density CCWDM Demultiplexer
Supports 16-channel cascading for multi-service isolation in campus
networks.
Passive CCWDM Module
Suited for harsh environments (e.g., industrial IoT) due to zero
electronic failure risks.
Unique Free-Space Technology
The CCWDM Mux adopts Free-Space technology, which uses light
propagating in free space to wirelessly transmit data. Inside the
device, adjacent signal channels are cascaded by parallel beam
instead of the fiber. This saves a lot of space for package box,
and the unique workmanship also helps CCWDM Mux Demux with low
insertion loss.
Comparison between CCWDM and CWDM
Insertion Loss <2.6 dB
The insertion loss of CCWDM Mux is about half of the conventional
CWDM Mux. This reduces the overall loss of the whole link, and
leaves more choices for the design of the solution.
Compact Package Design
CCWDM Mux uses the parallel beam for cascading instead of the
fiber, which saves significant space. The minimum dimension of
CCWDM aluminum box module is less than the 1/4 size of minimum CWDM
ABS pigtailed module.
