Passive solutions are mainly configured with passive wavelength division and 10G / 25G CWDM/DWDM modules.

The available types of passive wavelength division are: passive coarse wavelength division (CWDM) and passive dense wavelength division (DWDM).
Common channels for passive coarse wavelength division are 6/8/10/12/16, and common channels for passive dense wavelength division are 6/8/10/12/16/32/40.
CWDM Coarse wavelength division does not support optical amplification, and DWDM dense wavelength division supports optical amplification, which can be used in line sections with long fiber loss and long distance.
Colored light module: 10G SFP + optical module and 25G SFP28 optical module, corresponding to coarse wave CWDM optical module and dense wave DWDM optical module,
the specifications of the CWDM and DWDM module supplied by HTF are 10/20/40/80 km To choose from.
The configuration and quantity on both sides of the passive solution are the same, the same number of passive wavelength division + color light modules.
