High-Speed Data Transmission in Multimode Fiber

ABSTRACT: Multimode fiber (MMF) is the prevalent cable plant in many mil-aerospace systems. The multimode channel has bandwidth limitations due to modal dispersion. This program will apply channel equalization to the photonic link, leveraging techniques established for copper interconnect. We optimize the fiber launch condition to maximize the effective modal bandwidth (EMB). We will utilized built-in-test methods to measure the link bandwidth insitu and auto-negotiate to the maximum rate available. Lastly, this program will incorporate a ruggedized vertical connector (RVCON) has extremely low-loss optical coupling, offering increased bandwidth through higher power entering the receiver. This connector solves the cable problem in existing low-profile transceivers that have fixed fiber pigtails, prone to breakage during assembly and operation. BENEFIT: Higher data rate (>10 Gbps per fiber) over the installed MMF, including 50/125, 62.5/125 and 100/140 variants. Specific platforms/systems present transition opportunities. F-35 Enhanced video performance. The increased available bandwidth reduces the latency in real-time video systems and offers higher resolution imagery. F-22 - Increase performance of the backbone communication bus by a factor of 25X. B-2 5X increased in available bandwidth for targeting and communications systems
