CCWDM Module Application
1. Telecommunications Applications
*Fiber Optic System Capacity Boost: CCWDM modules in fiber optic
networks multiplex diverse wavelength optical signals into one
fiber. In metro network access, operators use them to combine
users' signals like Ethernet and voice onto different wavelength
carriers in one fiber, enhancing fiber utilization and cutting new
fiber installation costs.
*Long-Distance Transmission Aid: In long-haul links, while DWDM leads in high-capacity, CCWDM serves auxiliary roles. It transmits monitoring, backup data with lower bandwidth needs cost-effectively.

2. CATV Network Use
*Program Transmission Expansion: In CATV headends, CCWDM modules
modulate multiple TV channel signals to different wavelengths for
fiber transmission to sub-headends or users. Operators adding HD
channels can use it to expand capacity by multiplexing new and old
signals.
3. Data Center Interconnection Role
*Connecting Different Data Centers: As data center scale and number
grow, CCWDM modules interconnect them. They multiplex internal
network signals like server data and storage backups via fiber,
improving connection efficiency, bandwidth use, and reducing costs.
In cloud service providers' data center interconnections, it
enables high-speed data transfer.
HJY offers a compact CWDM module that provides bandwidth capacity
expansion for future network growth in one of the small packages.
Its compact size and unique carrier tray set it apart, and can be
installed in a variety of field situations.
The compact CWDM is ultra low loss, super thermal stability, and
excellent reliability, with smaller size compact design to save
much space in the application. Applicable to CWDM system and
optional special service
Compact coarse wavelength division multiplexers (CCWDM Mux) is the
mini version of CWDM Mux. Compared with traditional CWDM
technology, CCWDM technology uses free-space optics platform which
can significantly improve optical performance, in a package less
than 1/4 the size of conventional CWDM modules. Main advantages of
CCWDM Mux are high wavelength accuracy and stability, low insertion
loss, high isolation and low PDL(polarization dependent loss). It's
protocol and rates transparent supporting such applications as the
CWDM system, PON networks, and CATV Links.

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.
