Information is hereby requested for the Free Space Optics (FSO) links between the HBK Main Building, Genhouse and the village in a ring topology. Scope: The site survey will confirm line-of-sight clearance, identify potential obstructions, assess rooftop or tower mounting options, and evaluate environmental conditions such as fog, rain, dust, and lightning risks. Planning and design will include detailed link budget calculations, CAD layout drawings, and integration planning with the clients network, and redundancy definition, all of which must be approved before installation. Installation activities will involve the supply and secure installation of FSO terminals, mounts, power supplies with UPS integration, and precise alignment of optical beams. Commissioning will consist of full throughput, latency, and error rate testing, the delivery of as-built diagrams, and training for clients technical staff, culminating in a formal acceptance handover. Maintenance and support will be provided through a three-year SLA covering preventive inspections every six months, fault response within four hours for critical incidents and within twenty-four hours for non-critical faults, and spare part availability within forty-eight hours.
