Los componentes de red pasivos son componentes de red que normalmente no requieren alimentación eléctrica. Algunos de estos componentes pasivos principales incluyen acopladores/splitters, splitters selectivos de longitud de onda (WDM, CWDM, y DWDM), circuladores/aisladores, e interruptores ópticos. Están disponibles tanto para aplicaciones en modo individual (single mode - SM) como para multimodo (MM). Estas partes son fundamentales para la construcción de una red potente y sin errores. La utilización de componentes pasivos inadecuados en puntos clave de una red pueden tener un efecto negativo rápido y evidente sobre el rendimiento del sistema.
The VDL-002 is a miniaturized variable optical delay line designed specifically for OEM applications. With a delay range of up to 250 ps, this device is a superior replacement for the variable RF phase shifters inadequately adapted from the RF/wireless field for fiber optic communications.
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 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.
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...
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.
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.
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.
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.
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.
