Fiber optic technology

The technology of fiber optic

In 1965 Mr. Kao and Mr. Hockham discovered that they were able to transfer light through glass fiber with an insertion loss lower than 20 dB/km. The manufacturing of this type of fiber glass started four years later in the USA and has since evolved in the speed of light. Many years later in 2009 Charles K Kao was awarded the Nobel prize in Physics for groundbreaking achievements concerning the transmission of light in fibers for optical communication.

Already in the early 70s the founder of Micropol Fiberoptic, Anders Andersson promoted the benefits of fiber optic to the Swedish armed forces. But it wasn’t until 1981 when the Soviet submarine U137 was reported to have run aground in the Karlskrona archipelago, which brought light for the use of fiber optics in the Swedish armed forces and laid the foundation of Micropol Fiberoptic in 1988.

A lot has happened since then and today fiber optics is a cornerstone of modern society, revolutionizing communication, internet services, and data centers. It enables high-speed internet, reliable telephony, and efficient data transfer in various industries. Used in medical imaging, defense systems, and research, fiber optics has become essential for our interconnected world.

What is expanded beam?

The need for accurate and reliable communication have never been more important. The fiber optic technology allows for large amount of data to be transferred with low insertions loss. But the traditional physical fiber optic connector is fragile to dust and particles and are therefore not suitable for harsh environments. The need for a fiber optic connector that could withstand harsh environments was first developed for the defence industry and was the beginning of the expanded beam connector that we see today. But how does the technology work and where can the connectors be used?

MIL-DTL-83526 20/21

All the Micropol expanded beam connectors are according to the military detail specification MIL-DTL-83526 20 & 21 to be reliable in harsh environments and in crucial situations. We have since the start been supplier of choice regarding passive fiber optic to the Swedish Armed Forces, but what does the specification mean and in which application are the standard needed?


MIL-DTL-38999 is a popular and a widely used circular hermetic connector for military and aerospace applications where secure and high reliability are needed. The connectors are designed for cable-to-panel I/O applications and are always male/female connectors. The 38999 have nine different shell sizes and a wide variety of contact arrangements. Read more about the standard, in which applications you should use which connector and advantages of the different connectors.

Why fiber optic?

Fiber optic have a long history and Micropol was early adopters to the technology, and has delivered high quality fiber optic products and solutions for more than 30 years. Read more about the history of fiber optic, the benefits of the technology and how it works.


A fiber optic cable is a type of cable that contains one or more optical fibers, which are thin strands of glass or plastic capable of transmitting data using light signals. These cables are a key component of fiber optic communication systems, providing high-speed data transmission over long distances with minimal signal loss.
