Module Selection:
Optical modules are available in various form factors and data rates. The selection process involves matching the module's capabilities with the network's needs. For shorter distances, modules with lower data rates, such as 1 Gbps or 10 Gbps, might be sufficient, while long-distance connections or high-speed interconnects may necessitate modules with data rates of 40 Gbps, 100 Gbps, or even 400 Gbps.
