What is CCWDM(Compact Coarse Wavelength

Division Multiplexing)?

CCWDM is Compact CWDM (Compact Coarse Wavelength Division

Multiplexing), which is a wavelength division multiplexing technology based

on TFF (Thin Film Filter). It works in the same way as CWDM modules, except

that CCWDM uses free space technology (As shown in Figure 1), compared

with the common CWDM fiber cascading method (as shown in Figure 2). The

package size of CCWDM is smaller than CWDM and with lower insertion loss

and better consistency. CCWDM can be used to replace the CWDM products

in telecommunications, corporate networks, PON networks, cable TV and

other fields. The lower insertion loss makes the CCWDM module have lower

signal attenuation when used, thereby reducing the power requirements of

the signal transmitter.

HYC's CCWDM module uses free space technology to transmit optical signals

by using an independent sealed space. The working mode is the same as

CWDM, first input(output) signal from the COM terminal, and then output

(input) optical signal through TFF (film filter) for other port transmission.

CCWDM module can save more space by using parallel optical path cascading

of free space technology different from CWDM optical fiber cascading

method. HYC’s CCWDM module has mature production technology and

stable and reliable performance. It supports an ambient temperature of -40 ~

+ 85 ° C to ensure stable transmission of signals.
