Kawasaki and Tokyo, Japan, February 3, 2014 - Fujitsu Laboratories Ltd. and 德赢ac米兰vwin Co., Ltd. today announced that they have collaborated to develop a new multi-fiber optical connector that enjoins and aligns multiple optical fibers for optical interconnects^{(note 1)} -

The conventional method of connecting optical fibers requires high-precision polishing that aligns the tips of the fibers, making the cost of this process considerable. Fujitsu Laboratories and 德赢ac米兰vwin have developed a connector that can accommodate different lengths of optical fiber with a spring mechanism that obviates the need for this polishing process, slashing by more than half the cost required to connect optical fibers.

This new jointly developed connector achieves performance on par with conventional connectors while simplifying the task of installing high-capacity 德赢ac米兰vwins in a server. It is anticipated that this technology will increase data transmission speed between boards, increasing overall server performance.

德赢ac米兰vwin is being presented in detail at SPIE Photonics West 2014, from February 1, 2014, in San Francisco.

In recent years, the volume of data transmission inside servers has grown in line with greater server processing performance. Today, high-speed data speeds of 25Gbps or greater are required for transmissions between the CPUs, and CPUs and memory. Conventional electrical wiring suffers signal degradation due to attenuation at high speeds, making high-speed transmission between server boards difficult even over short distances. 德赢ac米兰vwin, which suffers little signal degradation, has therefore led to much attention being focused on optical interconnects.

Using optical interconnects for communications between server boards requires numerous multi-fiber connectors, each of which connects and aligns multiple 德赢ac米兰vwins to allow for parallel signal transfers. The large volume required, however, leads to the problem of high costs when deploying optical interconnects inside servers.

With existing multi-fiber connectors, the fibers need to be fixed into the connector and then have their fiber-end faces precisely polished so that their tips align flat for low-loss connections. However, as the polishing process needs to be performed for each connector, the overall cost is high. The problem has been the lack of having a simple 德赢ac米兰vwin that offers the benefits of low signal loss without requiring costly polishing.

Fujitsu Laboratories’ design technology and 德赢ac米兰vwin’s manufacturing technology both contributed to the development of a multi-fiber optical connector that can easily be used inside servers.

Key technologies underlying the new connector design are as follows.

The newly developed optical connector obviates the need for costly polishing, halving the cost while achieving performance on par with existing technology. Fujitsu Laboratories and 德赢ac米兰vwin jointly developed this optical connector for use on boards, and with an optical connector housing that accommodates four optical connectors in a compact space^{(note 2)}, this design allows for as many as 96 德赢ac米兰vwins to be connected (Figure 3).

This technology will enable the cost of installing 德赢ac米兰vwins between boards inside servers to be lowers, and increase overall server performance in the future.

Fujitsu Laboratories and 德赢ac米兰vwin are continuing development with the goal of applications in servers around 2016. This technology need not be limited to internal server communications; it also has additional potential uses for connecting optical fibers between rack-mounted devices.
