Fiber optic sensing environment pH
This review offers a comprehensive analysis of recent advances in optical fiber-based pH sensors, covering key techniques such as fluorescence-based, absorbance-based, evanescent wave, and interferometric methods. Measuring pH is a critical parameter in environmental monitoring, biomedical diagnostics, food safety, and industrial processes. Optical fiber sensors have proven highly effective for pH detection due to their exceptional sensitivity, rapid response, and resistance to electromagnetic interference. While pH determination is a commonplace laboratory practice, conventional commercial pH probes exhibit drawbacks of bulkiness, slow response times, and signal drift. PreSens is a world leader in the field of optical sensor technology.

Botswana upgrades fiber optic cable trenches
For the first time, northern Botswana has been linked directly to the Internet via fibre optic cable. This follows the completion by Liquid Intelligent Technologies of a fibre network extension from Ramatlabama to Ramokgwebana, a 730km independent network. Botswana telecommunications industry owes its success to the intrepid decision and visionary leadership which found it paramount to liberalize the telco sector to create a uniform environment for all players, culminating in the conception of Botswana Fibre Networks Ltd (BoFiNet). BoFiNet completed P100M network upgrades via citizen-owned comapnies, boosting Botswana's digital capacity and empowering local ICT companies through skills transfer. Botswana Fibre Networks (BoFiNet ), a 100% Government-owned company, has recently completed two (2) strategic projects to expand its. Botswana Fibre Networks (BoFiNet) has successfully completed a major project aimed at providing high bandwidth capacity to customers across the country.
