Description
Overview
GAOTek Ultra Compact Hybrid Mux Demux has a device 3 channels in C-band of DWDM are hybridized into 4 channels CWDM network, in consideration of CWDM wavelengths range from 1260 nm to 1625 nm covering all the range of DWDM wavelengths (1470 nm to 1625 nm). and DWDM wavelengths have much smaller channel spaces (0.4 nm or 0.8 nm) in compare with CWDM channel space, therefore, the CWDM wavelengths near DWDM wavelengths can be used to transmit the DWDM wavelengths.
Features
- Extreme small footprint and fiber in and out on the same side, easy to manage.
- Extreme low insertion loss, to improve quality and to extend transmission distance.
- Excellent thermal stability to work at wide operating temperature range.
- Each channel can be adjusted individually, to get high wavelength accuracy
- Extremely compressed optical path
- avoiding dispersion problems caused by optical path
- compensation between channels, excellent channel-to-channel uniformity
- Stainless steel house, laser welding package
- metal tube to protect fiber, suitable for harsh environment
