Optimization of optical modulation formats for high-speed short-reach connection
Jianjun Yu
Fudan University, China
With the popularization of data centre and other bandwidth hungry inter-connect applications, the desired capacity of short
reach optical network has exponentially increased to 400 Gbit/s or even more. Recent standardization efforts for 400 G intra-
data center connections specify link lengths of up to 2 km. 8×56 Gb/s or 4x100 Gb/s could enable such 400 G networks. Relative to
coherent detection. Intensity modulation/direct detection (IM/DD) is a good candidate in inter-connect due to its low cost. For 56 and
up to 100 Gb/s signal generation, a fewmodulation formats or schemes, such as pulse-amplitude-modulation (PAM4), discrete multi-
tone (DMT), duobinary and chirp-managed laser (CML) are proposed and experimentally demonstrated. However, considering cost,
size and power comsuption, the modulation format should be optimized for different networks to meet different requirements. In this
talk, we will discuss this issue how to optimize the modulation formats for different optical networks?
