Fibre Optic Links

Mobile communication users expect full coverage even in radio shadow areas, e. g. in road tunnels, underground stations or large buildings such as airports, railway stations, office blocks, shopping centres or sports stadiums, regardless of the mobile communication standard. For that purpose SPINNER has developed fibre-optic analogue links that allow loss-free broadband signal transmission in the frequency range from 50 MHz through 2.7 GHz over a distance of several kilometres, regardless of the used modulation.

We are using the most advanced technologies, e. g. DFB or FP laser diodes, to achieve top performance at a reasonable price. Low noise and excellent linearity are further features of our fibre optic links. We also offer options such as versions with increased transmitter input sensitivity, higher bandwidth, a 1,550 nm wavelength range and component sub assemblies with a single or a redundant power supply.

Fibre optic links made by SPINNER are in use all over the world, and their reliability, maintenance-free operation, high performance and design fully satisfy our customers. Their high quality and affordable price allow their use even in applications where economic considerations had so far forced users to make do without the advantages of fibre-optic systems.

The SPINNER FO-Transceiver Modules are used to transmit analog RF signals over Fiber Optics. These proven modules offer very high quality and best reliability. While integrating in a system, time of development as well as the costs of development are dramatically reduced. These modules come completely tuned and tested. Hence the production costs are also lessened. Due to the small and compact design, they can be easily integrated in each system and offer a maximum of flexibility to the design engineer.

The herein used DFB-type laser diode provides excellent linearity. This is the reason for the very low intermodulation distortion. Due to the integrated optical isolator, the noise figure is significantly small, even in the lower frequency range.

The Receiver is equipped with a PIN diode, which is characterized by a very low noise and high linearity. For amplifying the output signal, the Receiver is equipped with
a LNA.
