Q1: What's the function of OADM?
The main function of an OADM site is to add or drop one or more wavelengths from a multi-wavelength channel during transmission.
Q2: What is ROADM and FOADM?
(1) ROADM is reconfigurable OADM,
A ROADM site adds or drops single-wavelength or multi-wavelength signals to achieve dynamic wavelength grooming in multiple directions. It can also perform the reverse process.
ROADM is the mainstream OADM site type. A ROADM site can add or drop any wavelength, and wavelength pass-through at a ROADM site does not require manual fiber connections.
(2) FOADM is fixed OADM.
A FOADM site drops optical signals with a specific wavelength from multiplexed signals. It transmits the signals to an OTU or line board, and multiplexes the optical signals over an ITU-T-compliant WDM wavelength transmitted by the OTU or line board into the multiplexed signals.
Q3: ROADM vs FOADM, Which one is better?
ROADM is expensive with better function.
FOADM is cost effective.
You can choose it according to your project.
Q4. Do you have ROADM?
Sorry, at least now only have OADM.
