CCWDM 8+1Channel Compact Coarse Wavelength Division Multiplexer G657A1 Fiber Optic for Data Center FTTX
Takfly's compact wavelength division multiplexer/CCWDM module utilizes TFF (thin film filter) based wavelength division multiplexing technology. It operates similarly to CWDM modules, but employs free space technology resulting in a significantly smaller package size, lower insertion loss, and improved consistency.
- Low Insertion Loss
- Compact Size
- Ultra Stable and Highly Reliable
- Extended Operating Temperature Available
Takfly's CCWDM module employs free space technology with an independent sealed space for optical signal transmission. The optical signal is input/output from the COM port, while other ports transmit light signals through TFF (thin film filter).
Widely used in telecommunications, enterprise networks, PON networks, cable TV, and other related fields.
