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.
|Transmission band insertion loss||dB||≤1.4||≤1.7||≤2.0||≤2.5|
|Transmission Adjacent Isolation||dB||≥30|
|Transmission Non-adjacent isolation||dB||≥45|
|Fiber type||900um loose tube|
|Connector type||LC/PC(or customize)|
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.
CCWDM Free Space Technology
Normal CWDM Fiber Stage Mode
Compliance with International Standards
The CCWDM module of FOCC conforms to RoHS, Satisfies TelcordiaGR-1209 and GR-1221.
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.
Excellent Performance Parameters (WDM systems with low loss and high isolation)
Lower Insertion Loss
Lower insertion loss makes CCWDM module have lower signal
