Ruggedised optical connector

Volex Group plc has launched a robust IP68 rated optical connector, a multi-fibre optical connector for use in harsh environment applications. The new connector is said to maintain excellent optical performance in a temperature range between 85ºC and –40ºC. The Robust Optical Connector is a fibre-to-the-antenna (FTTA) connector designed for use on mobile telecoms cell-site masts, both for 3G and LTE (4G) networks. It connects into a remote radio head box (RRH) positioned close to the antenna arrays. The product has been created incorporating opto-mechanical design concepts that isolate internally floating optical components from the harsh external environment. This results in maximum optical performance independent of external effects. Dr John Hannigan, engineering director, Volex Europe (part of the Volex Group), comments, “The Robust Optical Connector is particularly suitable for FTTA applications in mobile telephone networks and is available in custom lengths. It is easily installable in the field, whether at the top of a mobile phone tower or down at the radio base station. The versatility of the product also makes it equally suitable for industrial, security and broadcasting applications, or indeed other applications where IP68 protection is required with high optical performance.” The advantages of FTTA technology are both cost and environment-related, up to 50% less power consumption compared to traditional copper solutions, with no feeder loss. Within the install phases, its small size and lightweight properties in comparison to copper or RF cable links mean it can be carried to site and handled easily at height, resulting in a shorter installation time. Optical cable assemblies enable data transmission at high bandwidth over longer distances, Weilly Diamond Industrial from Taiwan has specialised in the production of shaped PCD dies for over 20 years. Using controlled die geometry and excellent polishing techniques, the company has a customer base across the US and Europe. In addition to regular shaped dies, such as square, rectangle, hexagonal, triangle, oval and trapezoid, Weilly Diamond will manufacture irregular custom-shaped PCD from customer drawings, to suit individual requirements.

without the effect of interference or data surges. This is a key factor, particularly in mobile communication. Hannigan continues, “We are seeing typical insertion and return losses of less than 0.15dB and greater than 50dB, respectively, from the Robust Optical Connector when single mode optical fibres are used.” Volex Group plc – UK Website : www.volex.com The new optical connector operates independently ▲ ▲ of external environmental effects Thin rectangular PCD shaped dies are in growing demand for PV ribbon, which is an important component of solar cells. The thinnest PCD flat dies measure 0.1mm x 2mm and smallest square dies measure 0.1mm x 0.1mm. Weilly Diamond Industrial Co Ltd – Taiwan Fax : +886 3470 7162
