“…Three kinds of QD-WTLs and QD-SOAs were used in the experiments [9]. QD-WTLs #1, #2, and #3 covered 1030-1120 nm, 1115-1177 nm, and 1207-1300 nm, respectively.…”

“…In addition, to realize a 1000-channel class wavelength routing system using the T-band and the adjacent O-band, we have developed T/O-band-specific quantum-dot wavelength tunable lasers (QD-WTLs), quantum-dot semiconductor optical amplifiers (QD-SOAs), and arrayed waveguide gratings (AWGs) [6,7]. We demonstrated 4K ultra-highdefinition (UHD) video transmission in the T-band [8] and 10-Gbit/s transmission using the subset of the 1081-channel AWG router, which covers the broad wavelength range of the T/O-band [9].…”

The wavelength range of 1000-1260 nm, known as T-band, where T denotes "thousand", is one of the promising wavebands suitable for the future moderate-range optical networks. We have developed T-band specific semiconductor devices based on quantum-dot technology. However, the cutoff wavelength of optical fiber cables currently utilized in access networks, i.e., G.652 fibers, is specified to be less than 1260 nm. Therefore, the fibers do not fully support the T-band. This letter presents a demonstration of the feasibility of 10-Gbit/s transmission over G.652 fibers in the T-band by experiments.
