HDO570 WDM add/drop filter
HDO570 is a 1-channel wavelength division add-drop filter module for HDO fibre optic CATV link. HDO570 is used when one CWDM wavelength is inserted into a fibre or removed from a fibre. The option for xPON filter (1550/ 1490+1310 nm) is also available.
Fibre connectors can be located either on the front or the rear of the module. The module is passive, requires no power, and is mechanically compatible with HDX002 and HDX003 installation frames.
