New Seikoh Giken Developments

Seikoh Giken have been developing new fibre optic technologies and products for decades. Through collaboration with fusion splicer manufacturers, the Splice-on-Connector was developed. The Optical Electric Field Sensors resulted from work with NHK, Japan.

Splice on Connector

Splice-On-Connector enables field termination of optical patch cords and trunk cables with no epoxy or polishing required

Utilizes a high-grade, factory pre-polished zirconia ferrule/fibre and offers a compact body designed to fit existing patch panels

Fusion splicing technology combined with Seikoh Giken connector design technology achieves reliable, repeatable results

Meets all requirements of Telcordia GR-326-CORE Service Life Test
   
Optical Electric Field Sensors (OEFS)

Optical Remote Antenna

The receiver sensor is an optical waveguide using Lithium Niobate crystals and provides high sensitivity and broad bandwidth with only passive components.

Optical fibres eliminate receiving sensor power supplies and electrically isolate receiving sensor and hence antenna from the receiver electronics.
