What is CCWDM(Compact Coarse Wavelength Division Multiplexing)

What is CCWDM(Compact Coarse Wavelength
Division Multiplexing)?
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.
