Fiber optic networks

For speed and reliability over long distances, fiber optics is the standard.

since 2004ANRE · IGSU · IGPRISO/IEC 27001
Sudură de fibră optică cu aparat de splice — GreenSoft Constanța

High speeds and stable connections over long distances, immune to interference. We perform fusion splicing, splicing and reflectometric measurements (OTDR) for backbone networks between buildings, halls and work points. Whether you are connecting two building blocks or an entire industrial platform, you get a professional, measured and documented connection.

What we include

  • Fiber optic route design
  • Welding and connectorization
  • Measurements and certification
  • Integration with existing infrastructure

Frequently asked questions

When is it mandatory to use optical fiber instead of classic copper cables (UTP)?

Fiber becomes necessary for distances beyond about 90–100 m (the limit of copper), between buildings, in environments with strong electromagnetic interference, and where you need very high bandwidth. For trunks and critical links, fiber is the standard. For short distances inside the office, copper remains practical and sufficient.

What is the difference between fusion welding and mechanical fiber optic connections?

Fusion splicing fuses the fiber ends into a permanent junction with very low losses and maximum reliability — the professional solution. Mechanical connections align the fibers without melting; they are fast and temporarily useful, but have higher losses. For permanent networks we use fusion splicing.

What are reflectometric measurements (OTDR) and how do they help quickly troubleshoot a broken fiber?

The OTDR sends a light pulse through the fiber and traces the path with losses and junctions along the length. If the fiber is broken or has a problem, the device indicates the exact distance to the defect. This way you can locate the fault within a few meters, without having to dig or check the entire path randomly.

What is Single-Mode vs. Multi-Mode fiber optic and how to choose the right type?

Single-Mode has a very thin core, transmits over long distances (kilometers) and is ideal for trunks and links between locations. Multi-Mode has a thicker core, is more economical over short distances but limited in distance. We choose the type depending on the distances and the future evolution of the network.

Is fiber optic immune to electromagnetic interference in industrial buildings?

Yes. Fiber transmits light, not electrical signals, so it is not affected by motors, frequency converters, welding, or strong electromagnetic fields. That is why it is the preferred solution in industrial environments, where copper would suffer from disturbances and transmission errors.
