Features
- Compact, lightweight, and non-insulating
The sensing element used is optical fiber which makes the OCS compact, lightweight, and non-insulating. - Easy to install
Installation to existing electric equipment is easy. The OCS does not require the need to cut electric wire because it consists of a reflective type optical circuit and the measurement location point can easily be changed. - Immunity from electromagnetic
OCS is immune to electromagnetic noise, because all parts except for the electronic circuit consist of optical components. - Measurement of large current
Measurement of large current is possible, because the OCS unit does not need the use of iron cores which cause magnetic saturation. - High-speed response
OCS detects and transmits current by using optics and due to this advantage, the response for high-speed sensing is more efficient than conventional current sensors. - Long distance signal transmission
Long distance signal transmission is possible because waveform distortion and transmission loss are low.

1D Fiber Array – Orbray Co. Ltd.
Devices for connection to Optical Waveguide (OWG), Laser, sensors, and others.
Optical Fiber Arrays are devices used for Coherent Optical Communication Systems by connecting and coupling fibers to optical waveguide devices.
The array products position the optical fiber cores with precision and accuracy within the V-Groove Blocks by an ultra precision processing technolo-gy. The process requires accuracy on a submicron level in order to reduce the connection loss.
In addition, we also offer a unique, high density and accurate optical lead frame which is a low loss, high-reliability narrow pitch array which enables direct fiber coupling of high-density array devices of LDs and PD Waveguides.SKU: n/a - Connector, Electronic Components
Ferrules – Orbray Co. Ltd.
Orbray’s ferrule and sleeve products are highly regarded as worldwide international standards.
Fiber breakage during fiber insertion into the back opening of the ferrule can be drastically reduced by our original molding technology.
The zirconia ferrules and sleeves are our main products of fiber optic components, suitable for high end performance and quality for various fibers, connectors and device terminations.
Our zirconia ferrules are divided into 4 categories, single-mode, multi-mode, capillary and custom as well as other custom zirconia products with various shapes not associated with the fiber optic industry.
Orbray’s zirconia ferrules and sleeves are designed at our head offices in Tokyo, Japan and manufactured at our own factories based on a thorough production and quality control systems. All of our ferrules are inspected for outer diameter, inner diameter and concentricity by our proprietary inspection measurement gauges and methods.SKU: n/a
