Panasonic's new "Active Optical Connector V series Uni-directional 2 ch" supports high-speed transmission of large data at up to 16 Gbps.
Osaka, Japan - Panasonic Corporation announced today that it has developed "Active Optical Connector  V series Uni-directional 2 ch" suitable for device integration, which is capable of high-speed optical transmission of large data. Panasonic will start accepting orders from October 1, 2016.
The ever-increasing performance of medical devices, measuring instruments, industrial equipment and industrial printers has necessitated high-speed transmission of large data between board units and modules within such devices. This is needed to achieve high-speed data processing, such as handling high-definition images. A promising approach to meeting this requirement is optical data transmission, since it is less susceptible to electromagnetic noise, compared to electrical data transmission, and suffers little signal degradation. In particular, it is an effective means of data transmission in industrial devices and other equipment used in severe environments with high levels of electromagnetic noise. It also allows electrical isolation between boards and modules, which is quite beneficial, for example, in medical equipment that comes in contact with human bodies and sensitive measuring instruments. Future need for high-speed transmission of larger data is particularly expected for medical equipment and printers, which will need to handle 4K and 8K images. While Panasonic already has bi-directional 1-ch active optical connectors, the company will launch a new uni-directional 2-ch product that achieves high-speed transmission of large data at up to 16 Gbps to meet the need for larger data transmission.
Panasonic's "Active Optical Connector V series Uni-directional 2ch" features:
- Achieving high-speed transmission of large data with uni-directional 2-ch type
Broadband transmission rate: 20 Mbps to 16 Gbps (8 Gbps/ch)
Enables transmission at speeds up to 16 Gbps
(Panasonic's conventional products* : 20 Mbps to 6 Gbps)
- Achieving a compact device equipped with a built-in optical/electrical conversion function at the plug sections
Shape: 9.1 (L) × 12.7 (W) × 6.5 mm (H) [plug and receptacle are mated]
(Panasonic's conventional products* : Equivalent)
- Facilitating noise reduction for high-speed signals and electrical isolation
* Panasonic's conventional products* : Optical active connector (bi-directional 1-ch)
Signal connection between units, modules, and boards within equipment such as medical equipment, industrial printers, measuring instruments, security cameras, robots, and industrial devices (e.g.: Connection between main body control board and image processing board).
This product will be exhibited at InterOpto 2016 from September 14 to 16 at PACIFICO Yokohama and at CEATEC JAPAN 2016 from October 4 to 7 at Makuhari Messe in Japan.
1. Achieving high-speed transmission of large data with uni-directional 2ch type
Optical data transmission is capable of high-speed transmission of large data as a wire-saving technique compared to conventional electrical data transmission. Its applications are becoming wider, from communication infrastructure to connections between devices and, even further, to devices' internal connections such as the connection between boards and modules. In particular, medical equipment and printers are expected to handle more high-definition 4K and 8K images in the future, thus requiring high-speed transmission of larger data. Panasonic has commercialized a uni-directional 2-ch connector by adopting a silicon bench structure  that includes optical/electrical conversion circuits and optical fiber mounted on silicon substrates using Panasonic's unique microfabrication technology, thus achieving multi-channel integration. Furthermore, for this new product, we suppressed signal degradation by improving the high-frequency circuit design in the plugs. The product supports broadband optical transmission at 20 Mbps to 8 Gbps per channel, enabling high-speed transmission of large information at up to 16 Gbps. This will contribute to achieving higher definition and higher-speed processing of images handled by medical equipments as well as shorter inspection times by measuring instruments. The addition of this product, which provides higher-speed and larger-sized transmission, to Panasonic's lineup that already includes bi-directional 1-ch products will give customers a wider range of selection.
2. Achieving a compact device equipped with a built-in electrical/optical conversion function at plug sections
Multi-channel transmission has involved a device-size issue: Preventing optical signals from affecting adjacent circuits (i.e. crosstalk) requires that a certain distance and a particular structure be arranged between the channels. This product, which is equipped with a built-in electrical/optical conversion function at the plug sections, has achieved a compact device size by adopting the silicon bench structure that suffers little optical loss in the optical transmission paths and shows little effect on adjacent channels. This has eliminated the need to set up a distance and a structure between multiple channels, allowing integration with small substrates and modules.
3. Facilitating noise reduction for high-speed signals and electrical isolation
Electrical data transmission has become more susceptible to electromagnetic noise with the recent increases in speed, requiring more parts and labor-hours to reduce electromagnetic noise. On the other hand, while optical transmission suffers little noise at its optical fiber section and eliminates the need to reduce electromagnetic noise, its optical/electrical conversion circuit section is susceptible to noise in some cases. This product achieves noise-resistant capabilities, even during 16 Gbps high-speed transmission, by using a metal cover structure at the plug sections that excels in noise suppression. Furthermore, measuring instruments that handle high voltages require devices for electrical isolation between high-voltage circuits and signal-processing circuits to protect the instruments during electrical data transmission. This product, which converts an electrical signal to an optical signal, achieves both isolation and 16 Gbps high-speed transmission, well-suited for the data transmission by medical devices that contact human bodies.
