Japanese companies has developed 10Gbps plastic optical fiber transmission module and cutting tools

Present multi-communication industry has developed the concept of two transmission module section and special cutting tools for 10Gbps high-speed transmission plastic optical fiber (GI type POF). For 2020 television broadcasting as well as "8K Super Fine" medical image uses, wiring between devices and other processes to develop high-quality demand for the GI type POF is expected to expand. GI type POF cable is Keio Keio University, Japan Science and Technology Faculty, Professor Yasuhiro Koike at the core of development. With the completion of this development, in actual use the GI type POF connectors required and on-site cutting tools already available.

GI type POF transmission speed of 10Gbps, the transmission distance of about 50m. Its characteristics are: the metal cable (transmission speed of 3Gbps, sensing distance of about 7m) can be achieved compared to long-distance, high-speed transmission, and bending resistance than quartz fiber (glass fiber) outstanding, easy laying. GI type POF with silica fiber as a two-layer structure, as the core portion of the optical transmission path by a fluorine-based resin, wrapped around the coated portion is made of acrylic resin. In addition to developing a mass production method based on injection molding process outside diameter of the inner core portion is also thicker than the quartz fiber 10μm, reaching 80μm, and therefore has a margin of the optical alignment, compared with the quartz optical fiber, is also expected to reduce the system overall costs, which is a major feature.

When the GI type POF put to practical use, the first encounter is "cutting" questions. Quartz fiber end processing at the factory must, in addition to "cut" the need to implement things, "grind", which to connect. The original use of 200Mbps low-SI POF is a special type of cutting tool, capable of working at the construction site. However, when the SI type POF cutting tool used for GI type POF, it will cause damage to the cross-section, resulting in not high-speed transmission. In addition, GI type POF is a plastic material, and therefore there can not do that as the quartz fiber grinding problems. Therefore, multiple communication industry by adjusting the cutting speed and blade material, established GI type POF cutting technology, has developed a cutting tool can be used for the construction site.

In addition, as the company's main product connector aspect, this also developed a GI type POF of two transmission module. One is between the LC type optical connector of "passive type", with each one receiving channel. The other is inside the connector embodiment electro-optical conversion of "active type", with two each transceiver channel. Both modules will be available in January 2016.
