WAVELENGTH DIVSION MULTIPLEXING (CCWDM)

1. Compact size: The volume of a CCWDM module can be reduced to a fraction of that of a traditional CWDM module or even smaller, making it ideal for space-constrained applications (such as the AAU/RRU side of 5G fronthaul). 2. Lower insertion loss: By avoiding the series loss of TFF (Thin Film Filter), the total insertion loss of CCWDM modules is typically lower than that of traditional CWDM modules with the same number of channels. 3. Exceptional channel uniformity: The optical path of each channel is independent and symmetrical, resulting in very close insertion loss values across all channels and highly consistent performance. This is highly beneficial for the design of system power budgets.

Typical Application Scenarios of CCWDM

Inheriting all application scenarios of CWDM, CCWDM excels in scenarios with higher requirements for size, power consumption, and performance consistency:

• 5G fronthaul networks (Highly Recommended): At the base station antenna side (AAU) and device side (DU), space and power consumption are extremely valuable. CCWDM’s compact size and low-loss characteristics make it an ideal choice for passive wavelength division multiplexing (WDM) solutions in 5G fronthaul.

• Intra-rack interconnections in data centers: Within high-speed, high-density data centers, CCWDM enables higher connection density within limited physical space.

• Optical fiber network capacity expansion: Any scenario that requires CWDM functionality but demands smaller equipment and more flexible deployment.

• Test and measurement equipment: Integrated into portable or highly integrated test instruments.
