The primary differences between OM4 and OM5 cabling include their support for transmission distances and the type of multimode fiber. OM4 fiber supports distances up to 100 meters when using 100 Gbps transceivers (Option A), which is suitable for most data center and enterprise networking applications. OM5, also known as Wide Band Multimode Fiber (WBMMF) (Option C), extends this capability by supporting higher wavelengths in the 850 to 950 nm range, allowing for more efficient multiplexing and potentially longer distances or higher bandwidths under certain conditions. This makes OM5 a more versatile and future-proof option for organizations looking to deploy advanced technologies like shortwave division multiplexing.

Capacity based design with low to mid density - 100,000 ft² / 900 m² building 100,000/10,000 = 10 APsCoverage based design - 100,000 ft² / 900 m² building 100,000/2,500 = 40 APsHigh-capacity design - 100,000 ft² / 900 m² building 100,000/1,500 = 67 APsVery low-density, low coverage - 100,000 ft² / 900 m² building 100,000/500 = 20 APs

The deployment of Access Points (APs) in a wireless network design depends on the required density and coverage needed:

• Capacity based design with low to mid densityis often used in environments like office spaces where there is a moderate amount of users and devices. Fewer APs are required compared to high-density scenarios.
• Coverage based designtypically requires more APs than a low-density capacity design because the goal is to provide a wireless signal to all areas, regardless of the number of users.
• High-capacity designis for environments like stadiums or conference centers where a high number of users are expected to be concentrated in a particular area. Thus, a higher number of APs is needed to accommodate the user load.
• Very low-density, low coverageis suitable for areas that have few users over a large space, such as warehouses or outdoor areas. Fewer APs are required as the focus is on covering space rather than supporting a large number of devices.

The role of the Network Designer/Architect in a large-scale network infrastructure project is to develop a detailed technical design that meets the project's requirements. This involves authoring the low-level design documents, which include detailed network diagrams, device configurations, and implementation guidelines. The Network Designer/Architect must understand the technical specifications and business goals to create a solution that is not only technically sound but also aligned with the organization's objectives. This role is critical inensuring that the network infrastructure is designed to be scalable, reliable, and secure, providing a solid foundation for the organization's operations.
