GOF - future fiber optic cables
A glass fiber is slightly thicker than a human hair and can transmit data using light waves. It offers outstanding speed, volume and range of data transmission in an unprecedented scale.
Glass optic fibers (GOF), also known as light guides, form the basis of fiber optic cables.
A fiber optic cable consists of a bundle of multiple thin glass optic fibers or optic fibers, which are used in telecommunications as a transmission medium for wired communication systems and thus enable the simultaneous transmission of numerous high-speed Internet connections, telephone calls with the highest speech quality, as well as Full HD television programs.
Although fiber optic and copper cables dominate in their respective fields of application, fiber optic cables have much better transmission characteristics, higher bandwidths and ranges compared to copper cables, which is why the GOF technology is considered forward-looking. Moreover, fiber optic cables have a weight advantage over copper ones.
A specially shaped plastic coating provides protection against environmental effects and facilitates the blowing of fiber optic cables into empty conduits.
Copper or glass fiber
The question arises: What is better, copper or glass fiber?
In anticipation of the answer: The perfect solution is a combination of both materials.
While fiber optic cables are ideal for long-distance data transmission, copper cables offer many advantages on short distances. Therefore, they are much cheaper, easy to install and integrate into existing networks, as well as entail lower manufacturing costs.
Practically, fiber optic lines lead to the junction box or building distributor, where a media converter makes the transition to the copper line that extends into the building, apartment or office.
A combination of copper and glass fiber allows to achieve high speeds and save costs at the same time.
Here you will find an overview of all fiber optic cables.
Advantages of glass fiber at a glance
- Fast and high transmission rate (up to 1,000 Mbps upstream and downstream)
- Long range up to multiple hundred kilometers
- High bandwidth (approx. 60 THz)
- Insensitive to interference from electromagnetic fields and adjacent glass fibers
- No crosstalk
- High eavesdropping security
- No damage or fires due to parasitic currents (lightning, short circuit, etc.) possible
- No overvoltage protection required
- Small footprint compared to copper cables
- Easy to install
- Considered future-proof since no other transmission medium enables higher bandwidths
GOF in detail – glass fiber is not just glass fiber
As the name suggests, glass fibers are made of glass. However, this is not universally true as there are also plastic optic fibers. Although plastic optic fibers, which are known under the name GFRP (glass fiber reinforced plastic), have a lower performance compared to those made of glass, they are much less sensitive to installation. Due to the moderate popularity and higher attenuation values of plastic optic fibers, we do not include them in our range.
However, unused fiber optic cables that already run underground are referred to as dark fiber.
In addition, a distinction is made between monomode and multimode fibers, which meet different requirements depending on the field of application. Monomode fibers, which are also referred to as single mode fibers, have extremely low attenuation values and propagation delays, thus making them ideal for high bandwidths and long distances.
On the contrary, multimode fibers have much better transmission characteristics, which make them ideal as short-range connection cables and, for example, suitable for connecting switches in the building or floor area.
At all network levels: Applications of fiber optic cables
Media consumption via the Internet is ever increasing. There is a household automation in the private sector, the phone operates via the Internet, the consumption of online music and online video streaming portals increases, with surfing resulting in ever increasing amounts of data.
On the business side, there is an increase in the demand for high-speed Internet for the connection of locations, the integration and control of machines,complex software solutions up to the use of external data centers. The Internet speed is increasingly reaching its limits, which can be avoided by increasing the bandwidth using the GOF technology.
