A 32E1 unit is not automatically a safer purchase than a 16E1 unit. The correct capacity depends on active circuits, growth timing, central-site aggregation, Ethernet demand, protection, rack space, power, connector density, and the cost of a later change.
Choosing between single-mode and multimode optical transceivers is not simply a distance decision. The module, fiber plant, wavelength, connector path, host port, data rate, and optical budget must form one compatible link.
