Typically, fiber optic cable blowing machines require air pressure ranging from 8 to 12 bars, but the exact requirement may vary depending on the cable diameter and pipe diameter. This is the preferred method for pushing fiber optic cable through a pre-installed conduit. Also, the optical fibre diameter evolution from 250 to 200 and now 180μm will cable was considered very fragile and must be protected in the ground.

Genew Technologies and Zhongshi Wosen, both Chinese companies, will help the Democratic Republic of Congo (DRC) build its fiber optic network. On April 7, 2025, in Kinshasa, the Minister of Posts, Telecommunications, and Digital Affairs, Augustin Kibassa Maliba, signed a memorandum of understanding with two Chinese companies, Genew and Zhongshi Wosen. Through this partnership, the country officially launches the construction of its. 55 million fibre optic cable project, a significant leap towards enhancing its digital infrastructure. Congolese Fiber Optic Company (SOCOF SA) has reportedly signed a partnership with the Agency for the Coordination and Monitoring of Collaboration Agreements (APCSC) to deploy optical fibre networks along new roads to be built in the Democratic Republic of the Congo (DRC). The Democratic Republic of the Congo (DRC) is advancing its digital connectivity with the installation of a fiber-optic network, supported by the European Investment Bank (EIB), in collaboration with telecommunications firm, Bandwidth and Cloud Services Group (BCs).

Air blowing micro fiber optic cable (also called blown fiber cable, micro duct cable, or air-blown fiber) is a lightweight, high-fiber-count optical cable specifically engineered for installation using compressed air through pre-laid micro ducts. There are two basic methods of cable installation in a preinstalled duct – Pulling method and Blowing method. The 9A has a portable, petrol engine driven rotary vane compressor, producing 70 l/min of pulse free treated compressed air. These two models have recently received a comprehensive re-design, that has enhanced the specific features and improved the manoeuvrability and overall use of the unit, keeping the outstanding accessibility for ordinary and extraordinary maintenance.

Watch the fiber display for bubbles, fiber offset, or arc stability issues that could signify a defective splice. Fiber optic pigtails are used to connect fiber optic cables using fusion or mechanical splicing. What is a mechanical splice? What is a fusion splice? Why splice? Fiber splicing is one way to join two optical fibers together so the light energy from one optical fiber can be transferred to another. Static electricity is an enemy of fiber optics and splicer electronics, especially in dry environments and/or air conditioning.

With the right tools and techniques, you can efficiently repair damaged fiber cables and restore reliable performance. While a cut or damaged fiber optic cable can temporarily take your network down, it is possible to quickly fix the cable with the right tools. Fibre is often made of extremely thin strands of glass so if it is damaged in a particular area, then that section needs to be removed, and the remaining fibre would need to be carefully re-spliced.
