“…Currently, the interconnections at data center level are managed through electrical backplane with copper connections. However electrical backplanes have now reached their limit in terms of transmission capacity 1 and alternative optical solutions have recently been explored [2][3][4][5][6][7][8] . Besides optical waveguides embedded in standard FR4 boards 2,3 , which yet suffer from relatively high attenuation, external optical circuits, both flexible and frame-based, have been proposed.…”

A new optical backplane solution is proposed for high-capacity ICT apparatus. A modular, scalable and full-mesh bandwidth-upgradable optical interconnection between optoelectronic boards is guaranteed thanks to an optimized layout of standard MM 12-fiber ribbons which divides the overall backplane into several independent optical sub-circuits. The novel automated assembly procedure of fiber ribbons inside sub-circuits with a robotic work-cell is described. System validation of the optical backplane performed with commercially available MM 12-fiber transceivers @10Gb/s proved the feasibility of the proposed solution for future optical interconnections with terabit overall capacity

“…However, electrical transmission becomes increasingly problematic at high data rates and at a high density due to a higher level of loss and crosstalk. Therefore, a compact optical transceiver module and optical backplane for inner rack optical links have been discussed a lot [2][3][4][5]. Because ICT systems have several hundreds of links in a rack, a high density compact optical transceiver module that can be mounted two-dimensionally on a PCB is required for applying optical links into a rack.…”

We propose crosstalk reduction for the compact optical transceiver module. Crosstalk is composed of three elements: crosstalk resulting from electromagnetic coupling between adjacent signal lines, crosstalk resulting from electromagnetic coupling between transmission and reception, and crosstalk resulting from source impedance. Each element was reduced by adding a shield pattern and reducing the impedance of the pattern and that of the source pattern. We fabricated a module and demonstrated error-free transmission with simultaneous operation at 25 Gb/s by using a 2 31 -1 pseudo random bit stream (PRBS).
