摘要

This paper presents the Bit Error Ratio (BER) performance of 550 meter 850nm laser optimized 50/125 μm "enhanced" OM3 (TIA 492AAAC-A) or OM3+ graded index multimode fibers (MMF) using commercially available Vertical Cavity Surface Emitting Laser (VCSEL) based 802.3ae 10GBASE-SR compliant XFP transceivers. The power penalty at BER of 10~(-12), and its data pattern dependence are measured to characterize the digital transmission performance of the OM3+ MMF links, and the link penalties are compared with the Differential Modal Delay (DMD) of the fibers, encircled flux, and rms spectral widths of the transceivers. Although the pattern dependent transient noise in VCSEL are difficult to characterize, the experiments demonstrate qualitatively that it causes a rapid divergence of the link penalty as the DMD increases. The BER performance data indicate that the accuracy of the DMD measurement becomes crucial for extending the DMD based qualification to the OM3+ modal bandwidth (4700 MHz.km).
