Q. Why is the new 50μm multimode fiber superior to 62.5 fiber for 10 Gig applications?
A. Compared to 62.5μm fibers, 50μm fibers have a smaller fiber core, which results in less modal dispersion. Less modal dispersion results in higher bandwidth, enabling the transmission of faster data rates over longer distances.
Q. How much additional bandwidth does 50μm optical fiber provide?
A. Compared to 62.5μm fibers, 50μm fibers can provide nearly ten times more bandwidth. Effective modal bandwidth at 850nm for Corning InfiniCor 300 62.5μm fiber is 220 MHz/km vs. 2000 MHz/km for InfiniCor SX+ laser optimized 50μm fiber for 10 Gig applications.
