The advantages of CCWDM

Press release from: HYC Co., Ltd

CCWDM is a compact CWDM, Compact Coarse Wavelength Division Multiplexer. The CCWDM modules is the perfect means for adding capacity to your fiber optic network without installing additional fiber.

The main difference between CWDM and CCWDM is that the CWDM system uses a low-cost, no-refrigerated distributed feedback (DFB) laser, while the CCWDM collimator and filter are soldered on a common substrate, and the cascade structure is different.

A three-port filter for a particular CWDM wavelength channel consists of two lenses and a TFF of that wavelength channel to pass or reflect the beam based on its wavelength contents. Each filter's reflection port is connected to the subsequent filter's common port. The filters are connected by a fiber connector, which is a CWDM multiplexer.

CCWDM is more compact. Adjacent channels are cascaded, not through a bulky fiber cascade solution but rather in free-space, under collimated beam conditions.

The principle is to use an input lens to focus the optical signals of the wavelengths λ1, λ2...λn on the first filter; the optical signal with the wavelength λ1 passes through the first filter and is coupled to the first output lens. In the first output fiber, the optical signal of wavelength λ1 is separated; the remaining optical signals are reflected by the first slide to the next slide for optical signal separation; and so on, until all signals are separated. The coupling between the wavelength channels is achieved in the form of zigzag lines of light.

Based on the above principles, CCWDM has the following advantages:
1. Small package size
Due to the limitations from the minimum bend radius of a fiber circuit, the dimensions of the packaging cassette cannot be reduced significantly.In fact, most of the space in the box is unused. CCWDM's adjacent channels use parallel beams to cascade in free space instead of using optical fibers. Without the fiber used for cascading, the size of the CCWDM package can be greatly reduced. The standard 4CH CWDM has a size of 80×60×12 mm, and the CCWDM module of HYC Company has a size of 50×27×7.7 mm, which is about 1/4 of the standard CWDM package size. It can be widely used in high density environments.

2. Low insertion loss
Because CWDM and CCWDM adopt different packaging methods, the factors that cause loss is also different. The main factor affecting CWDM insertion loss is the coupling loss and filter loss between the collimator and the collimator. Due to different cascading modes, CWDM uses twice as many collimators as CCWDM, which inevitably leads to a large loss of CWDM, especially when the number of signals is large.

3. Good stability
Compact CWDM devices are less temperature sensitive than CWDM. The main reason is that the construct of CCWDM reduce the tilt of the reflected beam.CCWDM is connected with a rough filter side, the bonding force is much larger than that of CWDM, which effectively reduces the tilt of the reflected beam. The reflected beam tilt is the most important factor in the TDL of the device. For example, HYC Company 4CH CCWDM module has an operating temperature range of -40℃ to 85℃ and can be adapted to various environments.

4. High expandability
The CCWDM is available in 4/8/10 channels with an extended port channels, and can be expanded for more channels.

In addition, CCWDM has the characteristics of good temperature stability and high reliability compared with traditional CWDM. Due to its small package size, ultra-low optical path loss and temperature, CCWDM modules are widely used in wavelength division multiplexing systems, passive optical networks, and broadcast cable TV networks.

What is C band and L band in WDM (Wavelength Division Multiplexing)?
WDM (Wavelength Division Multiplexing) is a transmission technology that uses a single optical fiber to simultaneously transmit multiple optical carriers of different wavelengths in optical fiber communications. When the wavelength of light is different, the transmission loss in the fiber is also different. In order to reduce the fiber loss, it’s important to find the most suitable transmission wavelength. After a long period of exploration and testing, light with a
