Today, it’s the accelerating bandwidth provisions coupled with the growth of Passive Optical Network that drives the passive optical components market. Also, the usage of passive optical components to gain energy-efficient network solutions is growing in popularity.

What are Passive Optical Components?

They are the foundation stone of optical network systems. You can find most of these components, including optical cables, splitters, amplifiers, filters, circulators, and others used in the current data networks and FTTH applications.

The key market players are continuously focusing on designing, developing, and manufacturing innovative and tailored solutions that comply with international standards and meet the ever-increasing requirements of Passive Optical Networks for the high optical and mechanical specifications.

Let’s take a look at some of the essential passive optical components:

1. Pump Laser Protection

It is a passive component that enables supreme transmission from a discrete fiber-coupled laser diode around the center wavelength of the laser from being reflected into the laser.

You can find SM Pump Laser Protector, PM Pump Laser Protector, MM Pump Laser Protector in the market today. The most suitable pump laser protector for you will depend on the fiber type of laser diode. They can work for 1.0 um fiber laser and 1.5 um fiber laser.

Features:

  • Low insertion loss
  • Low cost
  • High reliability
  • High power handling
  • Excellent temperature stability
2. Optical Circulator

It is a multi-port (minimum three ports) non-reciprocal passive component. Its function is the same as that of a microwave circulator – to transmit a light wave from one port to the next sequential port with maximum intensity. However, it also has to block any light transmission from one port to the former port.

3. Fiber Collimator

It is a device used for collimating the light coming from fiber or for launching collimated light into the fiber. Fiber collimators can expand and collimate the output light at the fiber end or couple the light beams between two fibers. You have the option of both single-mode fiber collimators and multimode fiber collimators.

4. Optical Isolator

It is a passive optical component that enables light to propagate in one direction only. Optical isolators can protect light sources from back reflections or signals that cause instabilities and damage. The function of this component depends on the Faraday effect, which is used in the Faraday rotator.

5. Fiber Sensor(FBG)

It is a sensor that uses optical fiber either as the sensing element or a means of relaying signals from a remote sensor to the electronics that process the signals. Fiber sensors are immune to electromagnetic interference and do not conduct electricity. Thus, it can be used in places with high voltage electricity or flammable material such as jet fuel.

6. Pump Combiner

It is built based on the fused biconical taper technique. Pump combiners are usually used in a fiber laser, fiber amplifier, high power EDFA, biomedical and sensor systems.

A reputable and reliable manufacturer will have all the above passive optical components at high quality and reasonable prices.
