In this paper we exploit the centre-launching technique to allow single-mode propagation in multi-mode fibres and to guarantee full transparency to the transmitted optical signal for applications in board-to-board and data server interconnects. We show that this technique is robust to mechanical perturbations up to about 1 kHz, demonstrating that vibrations do not affect the transmission performances...
The analysis of the impact of mechanical perturbations on the system performance is an important issue to assure robustness in board-to-board and data server interconnections, as required by ETSI recommendations [1]. This robustness has to be guaranteed also in case of optical solutions [2], normally based on multi-mode fiber (MMF) communications, demonstrating easy handling and flexibility. In this...
The exponential growing of the requested bandwidth capacity for high performance computing systems requires the development of novel backplane solutions within the rack as well as for the rack-to-rack fabric interconnections [1]. The solutions currently used are based on copper interconnections via backplane, driven by a suitable transceivers subsystem. The evolution of the transmitting and receiving...
Optical interconnections and datacom applications will lead up to an increase of the bit rate to 12.5Gb/s in uncooled condition to maintain the low cost requirement. Nowadays, significant progress has been accomplished in the long-wavelength VCSEL technology, leading them to work at 10 Gb/s. We experimentally evaluated the capability of 1.3 mum VCSEL to operate up to 12.5 Gb/s. In particular, error...
We demonstrate 1.55 mum VCSEL to VCSEL injection locking that permits to propagate at 10 Gb/s over 40 km of SSMF with no penalty and without any dispersion compensation.
