Synchronization, retiming and OTDM of an asynchronous 10 Gigabit Ethernet NRZ packet using a time lens for Terabit Ethernet

Abstract

An asynchronous 10G Ethernet packet is synchronized and retimed to a master clock using a time lens. The NRZ packet is converted into an RZ packet and multiplexed with a serial 1.28 Tb/s signal.

Synchronization, retiming and time-division multiplexing of an asynchronous 10 Gigabit NRZ Ethernet packet to terabit Ethernet

“…The concept of a time lens stems from the time-space duality, which refers to the analogy between the paraxial diffraction of beams through space and the dispersion of narrowband pulses through dielectric media in time [6][7][8][9][10][11][12]. Since a spatial lens can be used to obtain the Fourier transform of a spatial profile at the spatial focus, a time lens can also be used to obtain the Fourier transform of a temporal profile at the temporal focus.…”

100-Gbps RZ Data Reception in 67-GHz Si-Contacted Germanium Waveguide p-i-n Photodetectors

“…In this paper, 80 Gbps and 100 Gbps OOK data reception using the 14 µm long Si-LPIN GePD are characterized, and clear open eye diagrams at 1550 nm wavelength are demonstrated using 80 Gbps and 100 Gbps on-off keying return-to-zero pseudo-random-bit-sequence data patterns generated using an optical time division multiplexing scheme [17], [18]. As the 14 µm long Si-LPIN GePD is still transit-time limited, the potential performance improvement in terms of responsivity using a 20 µm long Si-LPIN GePD is evaluated.…”
