• Fiber optic cables commonly come in multiples of 2 fiber increments, such as 6, 12, 24, 48, 72 and 144 fiber configurations. • Anticipating future growth during cable . MPO pre-terminated fiber optic cables utilize different glass types based on transmission distance and bandwidth requirements: Single Mode Fiber (e. The specific count size chosen for a project depends on several factors, including the intended application, the required data transmission capacity, and. Fiber optic cables use light to transmit data, while traditional cables, such as copper cables, use electrical signals. • Design engineers reserve spare fibers for potential breaks and future upgrades to the system.
