Future Optics’ compact coarse wavelength division multiplexers (CCWDMs) are integrated optical modules using Future Optics’ free-space optical platform to have collimators and filters bonded on a common substrate. In a package less than one-fourth the size of conventional 3-port CWDM modules, these CCWDMs significantly improve optical performance, while reducing manufacturing costs. Custom wavelengths and channel configurations are available.
Future Optics' 6CH UPG one side fiber CCWDM Mux Deumx device has a compact footprint of 6.5*28.8*50 mm and a maximum1.2dB insert loss, This device is specially designed for the purpose to upgrade Three-Port cascaded filters CWDM both in performance and in budget. It adopts Free-Space technology. Inside the device, adjacent signal channels are cascaded by parallel beam instead of the routing fiber, and all the collimators and filters are fixed on the same panel base, channel fibers are arranged at the same side of device.
Features:
● Compact footprint: 6.5*28.8*50mm and fiber in and out on the same side
● Extremely low insertion loss: maximum value 1.2 dB, totally improve transmission quality and extend transmission distance
● Excellent thermal stability: PDL 0.3dB, TDL 0.5dB
● High wavelength accuracy
● Wide operating temperature range
● Excellent channel-to-channel uniformity
Applications:
● CWDM system
● CWDM transceiver
● PON networks
● Telecom networks
● Broadband networks
● Science and lab
