We propose a large core multimode fiber with 100-µm core diameter for short distance communication that is compatible with existing transceivers designed for 50-µm diameter core multimode fibers. The fiber exhibits a bandwidth that is over four times higher than the 50-µm OM4 fiber, low bending loss, and large connector offset tolerance. We have studied the bandwidth capability through both detailed modeling and experiments. A prototype fiber was fabricated, and it achieves 24 GHz km peak modal bandwidth in the 850 nm window, and the wavelength window with bandwidth above 5 GHz km is more than 100 nm. The bending losses of the fiber measured at 850 and 1300 nm with an encircled flux launch condition exceed the requirements for bending insensitive multimode fibers. The fiber has much higher connector offset tolerance compared to conventional 50-µm diameter core fibers as has been exhibited by modeling and experimental study. The additional loss caused by up to 10-µm connector offset is only 0.3 dB. Transmission experiments using 25 G SR and 100 G shortwave wavelength division multiplexing transceivers over such a fiber show error-free performance over 500 and 300 m, respectively. The proposed large core multimode fiber can address versatile needs in short distance communication including the bandwidth for high data rate transmission and a wide wavelength window for wavelength multiplexed transmission. The large connector tolerance and low bending loss can also enable low cost, compact connectivity solutions with passive alignment and ease of handling.

具有高带宽和高连接器容差的大芯多模光纤，适用于宽带短距离通信

我们提出具有100-大芯多模光纤μ米纤芯直径为某一与设计用于50-现有收发器兼容的短距离通信μ米直径芯多模光纤。光纤的带宽是 50- µ 的四倍以上m OM4 光纤，弯曲损耗低，连接器偏移容差大。我们通过详细的建模和实验研究了带宽能力。制作了光纤原型，在850 nm窗口实现了24 GHz km峰值模带宽，5 GHz km以上带宽的波长窗口超过100 nm。在环形通量发射条件下，在 850 和 1300 nm 处测量的光纤弯曲损耗超过了弯曲不敏感多模光纤的要求。建模和实验研究表明，与传统的 50微米直径芯光纤相比，该光纤具有更高的连接器偏移容差。高达 10- µ造成的额外损耗m 连接器偏移仅为 0.3 dB。在这种光纤上使用 25 G SR 和 100 G 短波波分复用收发器的传输实验分别显示了超过 500 和 300 m 的无差错性能。所提出的大芯多模光纤可以满足短距离通信中的多种需求，包括用于高数据速率传输的带宽和用于波长复用传输的宽波长窗口。大连接器容差和低弯曲损耗还可以实现低成本、紧凑的连接解决方​​案，具有被动对齐和易于处理。
