Horizontal Link provides the physical layer for a unidirectional optical communication channel.
- A complete transmitter-receiver system for point-to-point free-space transmission.
- Co-propagating 1550 nm data and 980 nm guide beams combined through wavelength-division multiplexing.
- Active fast and slow beam steering that compensates pointing drift at the receiver.
- A configurable, protocol-agnostic architecture designed to integrate with your source, modulation and signal-processing chain.
At the transmitter, a wavelength-division multiplexer combines the user’s 1550 nm signal with a 980 nm guide beam and routes both through a common fibre to the launch optics.
A 6-inch refracting telescope expands the beam; adjustable optical spacing tunes its divergence to the deployment geometry for optimal collimation.
At the receiver, a second telescope collects the beams and dedicated optics separate the wavelengths: 980 nm for alignment and 1550 nm for the fast InGaAs communications detector.
