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.
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.
