• For transporting multiple SD-SDI or HD-SDI video signal over a limited fiber cable capacity
• When reducing infrastructure costs (cabling, electrical power consumption, space, etc.) is required—multiplexed video over fiber gives us an 8:1 ratio on cabling and support equipment
• Fiber is commonly used in any application where HD-SDI signals are found
