- Increase in Capacity With Reduced Fibers – Fitting more wavelengths onto a single fiber. This single fiber can carry more bandwidth. Fewer physical fibers will be used between the two sites.
- Flexible in Setups – Dynamically re-tune wavelengths without dropping connections. This may allow more control over the optical network.
- Easier Scalability – Normally, active DWDM can be easier to scale as the network grows.
- Expensive – The overall active DWDM setup fees are much more expensive compared to passive DWDM solutions. However, in the long term, this initial cost has an abundance of benefits.
- Complex in Configuration – There are many more components involved in active networks. Thus, the configuration will be a serious undertaking and require a solid understanding of optical networks.
