Alps Electric has developed the “FLGPJ Series” Narrow Aspherical Glass Lens suitable for compact, high-density optical transceivers. Mass production will begin in July 2017.
The establishment of broadband communication networks based on fiber optics and other technologies plus the recent spread of such mobile devices as smartphones and tablets have led to the rise of services involving the transmission and receipt of large volumes of data.
Examples are social networking services (SNS), gaming and video distribution. Data traffic over the Internet is increasing all the time as a result and the trend is expected to continue as Internet of Things (IoT) technology is embraced by a wide range of industries.
Infrastructure operators, who run data centers for storing data and the communication lines, are trying to support to high-capacity communication networks by downsizing optical transceivers and other equipment for fiber-optic communication systems to allow installation of multiple devices in the limited space available. Equipment therefore has to be more compact and of higher density, increasing the need for similar downsizing of the electronic
components inside them.
For optical transceivers, Alps Electric has so far carried out mass production of square aspherical glass lenses, with a width and height of 1mm. Now Alps has developed the FLGPJ Series, an aspherical glass lens with a narrow width and a chucking area.
The FLGPJ Series has a narrow width measuring 0.6mm across and the chucking area at the top improves ease of handling when mounting during end product assembly and when making adjustments, contributing to high-density mounting. And despite the compact dimensions, the lens achieves an effective numerical aperture (NA) of 0.5.
Furthermore, the FLGPJ Series employs lead-free glass, achieving compliance with both RoHS 6 and REACH regulations.
Alps Electric will continue contributing to the creation of smaller optical communication equipment with higher density by harnessing technologies in the areas of optical design, mechanical design, mold and die manufacturing, molding and simulation built up over more than 25 years serving the optical communication market, and through stable supply of high-quality products.
