In this paper we will discuss avenues to exploit the potential low loss and low linearity of hollow core photonic band gap fibres (HC-PBGF) at 2 microns wavelength. In particular, we will show recent developments in semiconductor devices to enable a 100Gbit/s transmission demonstration.
We demonstrate the use of MCF for power efficient ultra-high capacity long haul transmission. Feasibility of 105.1 Tb/s transmission over 14,350 km is shown using 12-core fiber and power equivalent of a single pump laser.
In this paper, we will demonstrate the possibility of opening a new telecommunications transmission window around the 2 µm wavelength, in order to exploit the potential low loss of hollow-core photonic bandgap fibers, with the benefits of significantly lower non-linearity and latency. We will show recent efforts developing a dense wavelength division multiplexing testbed at this waveband, with 100...
The capacity of optical communication systems can be continuously scaled by utilizing spatial division multiplexing (SDM) technology. However, this scaling has significant impact on the required optical and electrical power as the number of EDFAs increase. This constraint is crucial in long-haul undersea optical systems where electrical power for the entire system is fed from the landing points. Successful...
4×10Gbps WDM transmission over low loss HC-PBGF at 2μm wavelengths is demonstrated using a 2mm long QCSE based InP MZM with Vπ of 6V and ER>20dB. An OSNR of 25dB is required to achieve error free transmission.
Using optimized hybrid Raman-EDFAs and coded modulation with variable spectral efficiency we achieve 54 Tb/s capacity over 9,150 km transmission. We also achieve a capacity-distance product of 534 Pb/s∗km after 10,230 km distance.
This paper presents WDM transmission at 2μm over 1.15km of HC-PBGF with wavelength channels selected to span a 36.3nm waveband. A total capacity of 81Gbit/s was achieved using 4×12.5Gbit/s NRZ-OOK external modulation and 4×7.7Gbit/s 4-ASK Fast-OFDM direct modulation signals.
This paper reviews recent advances in transoceanic distance transmission technology including digital spectral shaping, coded modulation, variable spectral efficiency, and nonlinearity compensation to facilitate higher capacity and higher spectral efficiency.
A dispersion map that meets the conflicting needs of coherent and direct detection transmission is presented. Performance improvements over a conventional map are verified for coherent transmission by experiments and simulations.
