Site-specific millimeter-wave propagation prediction requires data of the environment under study, which is usually not available for indoor scenarios.
A differential 70 GSa/s track-and-hold amplifier has been designed and fabricated in a 320 GHz-fT InP double heterojunction bipolar transistor process.
NZDSF link designed for 32 x 10 Gbps CRZ capacity by using a mix of 24 OOK-RZ and 46 RZ-DPSK 10 Gbps channels.
This paper describes briefly the apparatus involved in this type of exchange and the means adopted for dealing with "Local," "Central Office," "Tie Line," "Conference," "Code" and "Fire Service" ca
We transmit 16 WDM channels using 20-Gbd QPSK over 12 spatial and polarization modes of 708-km few-mode fiber at a spectral-efficiency-distance product of 11328 km bit/s/Hz.
A DWDM self-seeded source achieves transmission in the O-band up to 90km SSMF at 2.5Gbps.
