Polarization Maintaining (PM) Fibers

With the continuous development of communication technology, as well as the application of the environment, special fiber is increasingly favored by the market, and related research and development has also entered the “high temperature” mode.

The Polarization Maintaining Fiber is one of the most representative. As a representative special fiber, the Polarization Maintaining Fiber is mainly used in fiber optic gyro, fiber optic hydrophone and other sensors and DWDM, EDFA and other fiber optic communication systems. Its application spree is also very wide, including aerospace, aviation, navigation, industrial manufacturing technology and communications.

Applications in sensors such as fiber-optic gyro and fiber-optic hydrophone make the name of the oblique fiber more interesting. Fiber-optic gyro, fiber optic hydrophonome can be used for military inertial conductivity and sonar, belongs to high-tech products. Fiber gyro is a fiber optic sensor gyro for inertial navigation, compared with other types of gyro, fiber optic gyro has a short start time, simple structure, light weight, no active elements, strong environmental adaptability and many other advantages. In the military aspect is mainly used in missiles, aircraft, ships and other weapons and equipment positioning navigation and navigation design, correction, in the civilian aspect, can be used in rail transportation, petroleum and petrochemical, mine exploration, port terminals, vehicle navigation and positioning and urban mapping. Fiber optic hydrophone is mainly used for acoustic propagation, noise, reverb, submarine acoustic characteristics, target acoustic characteristics and other detection in marine acoustic environment, and is an advanced detection method of modern naval anti-submarine warfare, underwater weapon test, marine oil exploration and marine geological survey.

Polarization Maintaining Fiber Components

Huihongfiber offers a variety of polarization-maintaining isolators that meet the needs of different applications. For example: single-polarization polarization-maintaining, dual-polarization polarization-maintaining. Online isolators with polarization-maintaining fiber outputs at both ends, or directly connected to the light source Pigtail type optical isolator and so on.

The polarization-maintaining circulator adopts the polarization-maintaining fiber input and output, has high extinction ratio, high isolation characteristics, excellent product performance, and can be used as an ideal device for polarization-maintaining optical path system.

We offer a full line of PM fiber-optic collimators. The standard product is a pigtailed polarization-maintaining collimator. The lens is a 1.8mm Grin lens, which is available in other lens types. The product has low back reflection and is used to collimate the fiber beam to achieve the desired beam diameter. It is widely used in laser diodes, photodiode detectors, acousto-optic modulators and other optical devices. Fiber Collimator Can be used in pairs to couple light into and out of other optics. Therefore, they are ideal for fiber-coupled packages in other devices.

The melted taper type polarization-maintaining fiber coupler is fabricated using leading fusion taper technology and process. The product has high extinction ratio and low added loss. Usually, it is made of Panda type polarization-maintaining fiber.

Polarization-maintaining optical wavelength division multiplexers (PM-WDM) are usually produced in two technologies, fusion taper technology (FBT) and micro-optical technology.

Polarization Maintaining (PM) Fiber Cables

Compared with traditional fiber jumpers, the polarization-maintaining fiber jumper uses a higher-precision connector and adapter for alignment to ensure the direction of the polarization-maintaining optical axis. The polarization-maintaining fiber connector and adapter have smaller Deviation, the keyway size used on the adapter to match the connector positioning keys is also narrower than the traditional adapter keyway to ensure good polarization elimination repeatability and low insertion loss.

Material optimization of polarization-maintaining (PM) fiber patch cords is key to determining the stability, consistency, and reliability of their applications. The optimization program of the polarization-maintaining (PM) fiber jumper in operation mainly includes winding, melting taper, mechanical grinding and polishing, etc. For various processing methods and application methods, the polarization-maintaining (PM) fiber jumper is required to be excellent. Compatibility, that is, the polarization-maintaining (PM) fiber jumper coating layer is required to have softness, friction resistance, tight adhesion to the glass fiber cladding, and small temperature deviation, and the optical fiber glass material portion is required to be easily ground. It is characterized by polishing, not easy to collapse, and not easy to crack. At the same time, it requires the polarization-maintaining (PM) fiber jumper to maintain adiabatic change during the high-temperature taper process, with small loss and low crosstalk degradation.

The application prospects of polarization-maintaining (PM) fiber patch cords are very impressive: in order to meet the needs of space or other high-radiation environments, it is necessary to explore the research of anti-radiation polarization-maintaining (PM) fiber patch cord products.
