Laser Link Installation in London

Positioning

The positioning of the Laser head is vitally important. It needs to be fitted in a remote location, yet hold the necessary line of sight, to connect the units together. The ideal location is to mount a Laser head to a structured wall, if this is not possible a tripod may be required. Due to the fact we cannot mount a tripod by drilling through a roof membrane, we glue 3 paving slabs into position.

Alignment

Once a head is mounted to a bracket our engineers start the process of head alignment. This is initially done by looking through a fitted telescope, with a cross hair, and using an audio frequency alignment tool. As a beam moves closer to alignment a high pitched noise is emitted. When the optimum frequency is reached an audio channel is opened. This allows the 2 engineers, working on each unit to speak with each other.

At the back of a laser head is a Link power gauge, when this reads maximum, the laser heads are locked into position. Then using software our engineers move the power settings down to 80%. This allows for an automated upsurge in power, if atmospheric or visual conditions dictate.

Each head is fitted with Automatic Transmit Power Control (ATPC) technology. This allows variable power settings to be automatically used, depending on atmospheric and visual conditions.

Alignment Testing

Head alignment is tested by carrying out packet simulation; here large amounts of data are transmitted across the Link. Our engineers need to be able to prove they can transmit 10,000 packets of data. This will allow a client to effectively use a voice over IP application.
