Fiberstore Passive Optical Components Solution

Posted on by

Passive optical components market is propelled by the accelerating bandwidth requirements coupled with the growth of passive optical network (PON). Usage of passive optical components to obtain energy efficient network solutions is gaining popularity. This article will introduce some Fiberstore passive optical components.

Optical Attenuators: an optical attenuator is a device that is used to reduce the power level of an optical signal. Optical attenuators are commonly used in fiber optic communications, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels.

Optical Circulator: an optical circulator is a multi-port (minimum three ports) non-reciprocal passive component. The function of an optical circulator is similar to that of a microwave circulator — to transmit a light wave from one port to the next sequential port with a maximum intensity, but at the same time to block any light transmission from one port to the previous port.

Fiber Collimator: a fiber collimator is a device for collimating the light coming from a fiber, or for launching collimated light into the fiber. It is used to expand and collimate the output light at the fiber end, or to couple light beams between two fibers. Both single-mode fiber collimators and multimode fiber collimators are available.

Optical Isolator: an optical isolator is a passive optical component that allows light to propagate in only one direction. Optical isolators are typically used to protect light sources from back reflections or signals that can cause instabilities and damage. The operation of optical isolators depends on the Faraday effect, which is used in the main component, the Faraday rotator.

Fiber Optic Sensor: a fiber optic sensor is a sensor that uses optical fiber either as the sensing element (intrinsic sensors), or as a means of relaying signals from a remote sensor to the electronics that process the signals (extrinsic sensors). Fiber optic sensors are immune to electromagnetic interference, and do not conduct electricity so they can be used in places where there is high voltage electricity or flammable material such as jet fuel.

Pump Combiner: a pump combiner is a passive optical component built based on fused biconical taper (FBT) technique. Pump combiners are widely used in fiber laser, fiber amplifier, high power EDFA, biomedical and sensor system etc. Three types of pump combiners are available: Nx1 Multimode Pump Combiner, (N+1)x1 Multimode Pump and Signal Combiner, PM(N+1)x1 PM Pump and Signal Combiner.

Polarization Components: polarization is the state of the e-vector orientation. Polarization components are used to isolate and transmit a single state of polarized light while absorbing, reflecting, and deviating light with the orthogonal state of polarization. Polarization components can be utilized in high power optical amplifiers and optical transmission system, test and measurement.

Fiber Collimator

If it is your first hear about fiber collimator, you may be very confused with it. What is fiber collimator? What types does it have? What is it used for? And where I can buy it? Today in this blog, I would like to have a detailed introduction about fiber collimator.

What is Fiber Collimator?

Fiber collimator is a passive device. It is a module that combines a fiber and a lens, as well as has a function to produce parallel beams. It is usually made of a curved mirror or lens with the light source placed at its focus, which is used to make divergent light into a parallel beam or coupler the parallel beam into the fiber. Fiber collimator is usually available with different wavelengths (850 nm, 980 nm, 1060 nm, 1310 nm, 1550 nm), which could be adjustable in practice. Here are some fiber collimator samples shown in the following picture.

Types of Fiber Collimators

By different light source placed at its focus, fiber collimator could be generally classified as four types. They are pin hole collimator, parallel hole collimator, convergent collimator and divergent collimator. Every type has its characteristic shown as follows:

  • Pin hole collimatorwhich – which consists of thick conical collimator having a hole in the bottom;
  • parallel hole collimator – which consists of an array of parallel holes that are perpendicular to the crystal surface;
  • Convergent collimator – which consists of an array of tapered holes that focus at a point;
  • Divergent collimator – which is an inverted converging collimator.
What is Fiber Collimator Used For?

Fiber collimator is widely used as a device for testing, calibration and measurement. In one pattern of fiber collimator, called target, is said to be projected to infinity. Placing a target in the focal plane of a collimator makes a uniform target appear to be in the far field. This phenomenon enables the use of collimators in training devices such as flight simulator.

When a surface is illuminated by a small light source, such as the target in a collimator, the illumination of points on the target surface off the light axis will be lower than illumination of the area of the surface on the axis. This phenomenon can be mitigated by interposing a fiber-optic faceplate between the light source and the target.

The use of fiber collimator for calibrating other optical devices allows users to check if all elements are aligned on the optical axis. It can make the setting of elements at proper focus and allow users to align multiple devices such as binocular, which ensures gunsights to be aligned with its respective gun barrels.
