Composants passifs

Les composants de réseau passifs sont des composants de réseau qui ne nécessitent généralement pas d'alimentation électrique. Les principaux composants passifs sont les coupleurs/séparateurs, les séparateurs sélectifs de longueur d'onde (WDM, CWDM et DWDM), les circulateurs/isolateurs et les commutateurs optiques. Ils sont disponibles pour les applications monomodes (SM) et multimodes (MM). Ces pièces sont essentielles à la construction d'un réseau puissant et sans erreur. L'utilisation de composants passifs inadaptés à des endroits clés d'un réseau peut avoir un effet néfaste rapide et notable sur les performances du système.



A suite of advanced polarization test instruments specially designed for testing the quality of fiber coils ensures the consistent production of high performance coils. GPCs´ PM coils can be wound with different winding patterns such as quadrupole, octupole, or other types to minimize the Shupe effect, which degrades the performance of a fiber gyro under temperature-varying conditions.

Winding a large fiber spool is easy, but making compact, low loss fiber coils requires attention, precision, and skill.

These connectorized couplers are free of fiber pigtails and ready to be inserted in optical systems without the headaches of tinkering with fragile and messy fiber pigtails.

GPC-PMC

The polarization maintaining filter coupler can either split the light from an input PM fiber between 2 output PM fibers, or can combine light signals from 2 PM input fibers into a single PM output fiber.

This device can be used either as a polarization beam combiner to combine light beams from two PM input fibers into a single output fiber, or as a polarization beamsplitter to split light from an input fiber into two output fibers of orthogonal polarization states.

GPC-FRM / NFRM

The Faraday rotator mirror is a fiber optic polarization rotation mirror designed for fiber optic networks and measurement applications. The state of polarization (SOP) of the reflected light is rotated 90 degrees from that of the input light.

GPC-ISO / NISO

These isolators are the smallest in size but the highest in quality in the market. They are ruggedly built to function reliably in a wide variety of environments.

General Photonics’ fiber optic circulators are compact, high-performance light-wave components that separate signals traveling in opposite directions along fibers by transmitting signals from port 1 to port 2 and port 2 to port 3, while blocking signals traveling in the opposite directions.

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.
