- Easier Setup – Plug and play simplicity. There is no need to tune wavelengths for all the connections.
- Cost-effective Solution – Fewer components & less engineering time. The high-channel density substantially saves on long and short-term expenses.
- Limited Scalability – The DWDM network is restricted to fewer wavelengths on the transport fiber. Thus, more passive components will be adopted when expanding as the network grows. However, the more passive devices, the more difficult it can be to manage.
- Inconvenient Control – If you need to change a wavelength or connection, you’ll have to take the network out of service and disconnect the physical cabling as the wavelength is tied to the specific optical cable.
