A dozen light based links from Alphabet spinout Taara now carry up to 20 Gbps across Africa's biggest commercial hub, where trenching is expensive and fiber cuts are routine.
Lagos' fiber backbone doesn't fail because the technology is weak. It fails because the ground is expensive to dig and easy to cut. Over the past two years, Liquid Intelligent Technologies has built out an answer to that constraint: roughly a dozen wireless optical links that move enterprise data through open air, no cable in the ground, no trenching permit, no spectrum license.
The links are made by Taara, an independent Alphabet company spun out of X, the long-shot projects lab that also produced Waymo and Wing. Taara's Lightbridge product sends narrow, invisible beams of light between two fixed terminals, with no fiber between them. Each link is rated for up to 20 gigabits per second across up to 20 kilometers in clear line of sight, with installations measured in hours rather than the weeks a fiber build typically takes.
For a megacity of more than 20 million where civil works are slow and construction crews regularly sever buried cables, those numbers map to a real business problem. Eugene Uka, on the record, called deployment speed the most significant advantage. Taara's Africa regional lead Bhavesh Mistry was more direct: fiber remains essential, but there are many situations where deploying fiber quickly or cost-effectively is difficult.
Liquid is not positioning Taara as a fiber replacement. The carrier runs an existing fiber network that already hands off at points of presence inside Africa Data Centres and other Lagos facilities. Taara's beams are the last mile and the redundancy lane. They get a bank, an ISP, a hotel, or a utility onto Liquid's network when trenching isn't an option, and they keep the link up when a fiber cut elsewhere in the city would otherwise take the customer offline.
The deployed links serve banks, internet service providers, hotels, and a utility company. Those are enterprises for which the binding limit on network uptime is the rate at which construction crews sever buried cables. The same product also offers a third lane: a quickly re-routable path when an excavator working on a different project has just cut somebody else's fiber.
Outside Lagos, Taara's Lightbridge is deployed in more than 20 countries, with operator customers including T-Mobile, Airtel, Digicel, Liquid, and SoftBank. The Lagos deployment is notable less for the technology itself than for the carrier and the demand backdrop behind it: a dense, fast-growing commercial hub where cloud, digital payments, and enterprise apps are pushing bandwidth requirements faster than the city's streets can be dug up.
Free-space optical links need a clear line of sight and can be disrupted by heavy rain, harmattan dust, or building sway on the kind of tall, lightweight structures common in Lagos. The vendor's 20 Gbps / 20 km figure is a rating under favorable conditions, not a measured field average, and Liquid has not published uptime or cost-per-Gbps data against trenched fiber in the Lagos market. The two-year buildout is best read as a complementary deployment, not a measurement campaign.
Liquid is now exploring expansion to Abuja, Ibadan, and Kano. The constraint the company is responding to is the same one in each of those cities: the cost of putting fiber in the ground, and the rate at which that fiber is cut once it is there. Whether Taara's beams scale beyond Lagos depends less on the optics and more on whether the carrier can keep finding customers whose fiber-cut exposure is the binding limit on their network. The dozen links in Lagos suggest the answer for now is yes.
