Single-channel fiber rotator makes the fiber coupling losses – Merfilong
Do you know what a single-channel fiber rotator does? This device is mainly to improve the coupling efficiency of the signal, greatly reduce the coupling loss of fibers, and have the advantages of small size and low cost. If you are interested, you will use Merfilong. Xiaobian will learn about it!
Fiber rotary connector
The fiber-optic rotary connector is required to reduce the light signal loss and the amount of rotation of the optical signal, the signal coupling efficiency is the ratio of the output power and the input power during the coupling process, and the signal coupling efficiency is a standard, and the signal is measured. Coupling efficiency is determined by the coupling loss of two fibers in the fiber rotary connector. To make the signal have a high coupling efficiency, the coupling loss of the fiber is smaller.
The fiber skull ring can be divided into single-channel fiber slip ring and multi-channel fiber slip ring, wherein the fiber pulley of single-channel is small, the cost is low, and the application is the largest device.

Fiber slide initial connection method
The initial connection method is the two fiber direct coupling, and the easiest way is the initial product of the fiber optic connector to the fiber optic rotary connector upgrade. Since the fiber core diameter is very small (single mode fiber is 9UM, multimode fiber is 50 um or 62.5 um), the two fibers are difficult to align, and it is necessary to ensure that the superficial mechanical structure is required. If the fiber optic connector function is simply implemented, the axial precision is less than 1 um can be achieved by the ceramic ferrule and the ceramic sleeve, and the axial precision can be achieved, but since the fiber rotary connector requires high speed rotation, it is necessary to join the bearing and other mechanical parts and mechanical structures. It is much more complicated than fiber optic connectors, so it is difficult to achieve fiber rotation alignment. To solve the difficulties of direct coupling between fibers, it is necessary to reduce the corresponding machining accuracy, generally to add optical signals between the two fibers between the optical fibers. Common lenses are microlenses, self-focus lenses, and fiber bundles, most common and optimal methods are to form fiber collimators as coupled devices with self-focus lens. The optical fiber collimator is placed at a collimated lens focus, so that the light beam emitted by the fiber is collimated, or parallel light is focused on the focus of the lens, so that the optical coupling into the fiber, continuing transmission .

The above is the related introduction of the single-channel fiber rotor, the device is connected very simple, just directly coupling two fibers, if you need to rotate at high speed, you can join the bearing machinery, but also want to know more information. Pay attention to the Meilong website!
