CCWDM module of FOCC is a wavelength division multiplexing technology based on TFF (thin film filter). It works in the same way as the CWDM module. The difference is that CCWDM adopts free space technology, Compared with the CWDM module, its package size is greatly reduced, and the insertion loss is lower and the consistency is better. It can replace CWDM products and be used in TC, enterprise network, PON network, CATV and other fields.

CCWDM module 11

Free Space Technology

The CCWDM module of FOCC uses free space technology and uses an independent sealed space to transmit optical signals. It works in the same way as CWDM. It inputs (outputs) optical signals from COM, and then outputs (inputs) optical signals through TFF (thin film filter) at other ports.

Compliance with International Standards

The CCWDM module of FOCC conforms to RoHS, Satisfies TelcordiaGR-1209 and GR-1221.

CCWDM module 8

Compact Design

The CCWDM module of FOCC adopts parallel optical path connection stage, which is different from the optical fiber connection stage of CWDM, which saves significant space. The package size of CCWDM module accounts for about 1/4 of CWDM.

The package size of CCWDM module accounts for about 1/4 of CWDM.

CCWDM module 6

Excellent Performance Parameters (WDM systems with low loss and high isolation)

Lower Insertion Loss

Lower insertion loss makes CCWDM module have lower signal
attenuation in operation, thus reducing the power
requirement of signal transmitter.

High Isolation

The higher isolation value enables sufficient signal
isolation during multi-signal transmission in the
CCWDM module, effectively preventing crosstalk between
signals and causing distortion of the transmission signal.

Mature Production Process

The CCWDM module of FOCC has mature production technology,
stable and reliable performance, supports the work in the
harsh environment of - 25~+70 ℃, and ensures the stable
transmission of signals.

Application

The product of CCWDM module of FOCC has the characteristics of low insertion loss, high channel isolation and high environmental stability and reliability. It adopts free space technology and compact package size design. It can replace CWDM products and be used in TC, enterprise network, PON network, CATV and other fields.
