The small form-factor pluggable (SFP) and 10 Gbit/s small form-factor pluggable (XFP) modules are supported.
The client side and WDM side of the optical wavelength conversion boards of the OptiX OSN 1800 can use pluggable modules. When you need to adjust the type of accessed services or replace a faulty module, you just need to directly replace the module without replacing the board.
