For the optical data transmission via POF media converters are used. Electrical data signals are converted into optical signals with an advanced modulation technique. The light spectrum is within the visible light range, currently red light with typ. 650nm. At the receiver side the optical signal is, converted back into an electric data signal. The used transmission protocol, IEEE 802.3.u, is internationally standardized. The modulation and communication technology for Gigabit Ethernet over POF is currently in the standardization process in IEEE WG.

Homefibre offers a wide range of media converters and optical POF switches for the installation of Fast Ethernet and Gigabit Ethernet Network.

An optical network has many key advantages:


Optical data transmission is immune to electromagnetic interference. The optical cable does not cause any electromagnetic radiation (electro-smog).

Low Power Drain

Implementation of electrical signals into light occurs without losses and with high energy-efficiency.

Standardized Transmission Protocol

The data transmission of IP packets and data streams via Fast Ethernet IEEE 802.3.u. and IEEE (Gigabit Ethernet) as well as required Quality of Service mechanisms are integrated in the active components and the access gateway (router or CPE [Customer Premise Equipment]).

A POF network can be installed following the architecture of structured cabling. However, the optical core network provides more and mainly new ways to install an innovative network infrastructure In combination with the electrical installation, it offers a comprehensive data backbone for all IP applications. A star or tree structure can be installed anywhere in the house. New network applications and new services can be integrated easy.

Standardized Interfaces

The interfaces to the network applications are conventional RJ45 data ports or WiFi via wireless access points. By combining optical data cable and wireless technology an optimum coverage and supply for fixed and mobile applications is provided in the house.

The slim POF cable (2.2 / 4.4 mm) can be arranged with little space even in a small distribution cabinet and be installed either in existing conduits or under frame boards or carpets.

* IP = Internet Protocol over Ethernet


The Polymer Optical Fibre, also called POF, is being used and approved for years in industry and the automotive industry for data transmission as well as for lightning purpose. The POF data cable is a high tech duplex cable with a core diameter of 1mm. One fibre is used for transmission and the other fibre is used for receiving. This increases the transmission length and raises the data transmission quality and bandwidth.

The optical cable may be placed next to all electrical wires due to its galvanic non-conduciveness. For the core fibre we use the well approved Step Index fibre (SI-fibre). This high quality fibre is made of PMMA (Polmethyl-Metharcrylate).

Advantages of POF cable:

  • easy installation
  • easy termination
  • sturdy, safe and free from radiation
  • visible light for visual proof of function
  • galvanically non-conducting, no lightning issues

Gigabit Ethernet over POF

With the availability of Gigabit transmission over POF the installation of powerful networks becomes much easier.

KD-POF Gigabit Technology is currently to be standardized in the related IEEE working group.

The ideal transmission distance for Gigabit transmission with red LED is 50m.
Through the adaptive bandwidth adjustment Gigabit Ethernet connections up to 90m can be realized.
