Passive Components

The LT900 Series of 1xN (1x3-1x26) optical switches combine world class switching speed with low insertion loss and excellent repeatability.

The 1xN switch LT1000 is electrically controllable and has very good values ​​with regard to insertion loss and repeatability.

GPCs' motorized variable optical delay line provides precision optical path length adjustment of up to 560 ps, single-pass. Driven by a DC motor with an integrated encoder, the MDL-002 has a resolution of less than 0.3μm (1 fs).

General Photonics’ motorized variable optical delay line provides low cost, precision optical path length adjustment and delay scanning functionality. This addition to the MDL product line is specifically designed for OEM applications that require continuous scanning capability and a small footprint.

AOI is a leading manufacturer of optical semiconductors for demanding analog and digital transmission systems. The portfolio includes analog optical components, digital optical components and optical data transceivers.

GPCs alle Festkörperpolarisationsschalter können die SOP des einfallenden Lichts schnell und wiederholbar um einen festen Winkel, entweder 45 oder 90 Grad, drehen. Sowohl Single-Mode- als auch PM-Faser-Pigtailed-Versionen sind verfügbar.

This patented device comes in a package as small as 85 × 60 × 10 mm for lasers with coherence lengths less than 10 meters. Devices for coherence lengths in the kilometer range can be custom made in a larger package, with nominal customization fees.

PMD and PDL are important considerations in many applications, especially high data-rate communications. With the development of high precision test equipment and tighter-tolerance systems, a need has arisen for extremely precise calibration standards.

GPCs’ fixed differential group delay lines eliminate the need for precise measurement of PM fiber lengths to add defined amounts of first order PMD to a system.
