Optical fibre connecting all Greenspec elements to the central computer

A single optical fibre line runs through the whole greenhouse instead of multiple copper cables.

Greenspec uses a single computer transmitting the input and output information over one optical fibre cable.

The installer can easily connect this cable. He can fit it simply by hand. No risk of damage from lightning discharge, because there is no electrical charge on the cable. Much cheaper than copper wire (and no copper theft).

Installing a POF cable is quick and easy

In each unit on the line you find an optical connection board, the Opto AFP board. The board on the computer is a special one called Opto GSC, as it communicates with the software over an USB connector. But all the different AFP units use the Opto AFP Board.

The optical cable comes in rolls of 500 m. Your installer can quickly cut and connect it.

First you cut it with a special tool. Then after that you tighten the connections by hand and so each connection is made in a few minutes. Greenspec uses a double cable.

It means that the data can go in two directions. So this makes it much safer, because the communication can go on if one direction is blocked. The lifetime of the Opto AFP board is over 5 years.


The new Kevlar reinforced optical fibre can directly be rolled out in the greenhouse. It needs no protecting mantle. You save on the cost of protecting tubes and especially in inserting long lenghts of POF optical cable in these tubes.


Standard POF is delivered in 500 m rolls, easy to cut. Maximum translission distance 120 m


The small optical connection board is present on all AFP units, once these are all connected, communication can start to the computer..

The new webapp is progressing quickly and will become a very handy tool for all Greenspec growers to watch and control the greenhouse from anywhere.
Greenspec has launched a new compact but very complete mixing station that is regulated by our own greenhouse automation system. We now add options for larger systems within the same high quality concept.
