CXF085 DAx Diplex filters
The CXF085 DAx are plug-in diplex filters with a downstream attenuation, covering the frequency ranges 5…85 MHz / 105…1218 MHz.
The CXF085 DAx high-performance plug-in filters are designed to be used at outputs of optical nodes or amplifiers. They have normal upstream behaviour, but there is an extra loss added on the downstream path. This attenuation offers a possibility to fine adjust downstream signal levels of individual RF ports.
These plug-in diplex filters come in three varieties.
- CXF085 DA2, 5…85 / 105…1218 MHz, 2 dB DS attenuation
- CXF085 DA4, 5…85 / 105…1218 MHz, 4 dB DS attenuation
- CXF085 DA6, 5…85 / 105…1218 MHz, 6 dB DS attenuation
