Passive network components are network components that usually do not require any electrical power input. Key passive components include couplers/splitters, wavelength-selective splitters (WDM, CWDM, and DWDM), circulators/isolators, and optical switches. They are available for both single-mode (SM) and multi-mode (MM) applications. These parts are crucial for building a powerful and error-free network. Using unsuitable passive components at key locations in a network could have a quick and noticeable detrimental effect on system performance.
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.
Winding a large fiber spool is easy, but making compact, low loss fiber coils requires attention, precision, and skill.
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.
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.
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.
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.
