Future Optics provide advanced 800GHz LAN-WDM mux demux solutions with extra low IL, extra compact size, low dispersion and wide passband, by leveraging proprietary thin-film filter fixing process and state-of-the-art optical path length control technique. Custom wavelengths and channel configurations are available upon request.
Future Optics' 4 CH UC LWDM has a 20*10.8*6.5mm small package size and 1.0 dB low insert loss at industrial temperature range. It adopts Free-Space technology. Inside the device, adjacent signal channels are cascaded by parallel beam instead of the routing fiber, thus the reliability is significantly improved. UC LWDM Mux Demux is usually integrated inside LWDM transceiver for its small footprint and also used 5G fronthaul network where wavelengths are packed tightly together over the O-band, up to 16 wavelengths in 800GHz grid.
Features:
● Extremely small footprint: 20*10.8*6.5mm and fiber in and out on the same side
● Extremely low insertion loss: maximum value 1.2dB, totally improve transmission quality and extend transmission distance
● Excellent thermal stability: PDL 0.3dB
● High wavelength accuracy
● Wide operating temperature range
● Excellent channel-to-channel uniformity
Applications:
● LWDM system
● LWDM transceiver
● 5G fronthaul networks
● Telecom networks
● Broadband networks
● Science and lab
