How do fiber optic cables meet today's connectivity needs?

Fiber optic and cable connection arrangements are the background technologies for modern communications systems to achieve high speed, wide coverage and increased bandwidth. Individual components such as fiber optics, cables, connectors, and end-to-end fiber optics have evolved over decades to support current and emerging applications. Today, the need for data has reached new heights, especially during and after the pandemic. To meet this demand, existing traditional cable deployment methods are no longer sufficient and 10x fiber needs to be deployed at 3x speeds.

Major technology and capital expenditure changes

Growing data demands are putting a lot of pressure on fiber optic factories. Upgrading fiber optic equipment is inevitable and designing smarter cable deployment methods is the need of the hour. The main reasons for such data requirements are:
  • 1.The arrival of 5G
  • 2.Large data centers installed by cloud computing companies
  • 3.Connect everything with IoT
  • 4.Virtualization (software interrupts the network)
  • 5.Technological changes affecting fiber optic cables

Judging from the 20-year CAGR (compound annual growth rate) from 1997 to 2017, the fiber deployment speed exceeds the world economic growth rate by 5 times. From 1970 to 2008, the deployment rate of 1 billion feet of cable dropped significantly from 38 years to 2 years. From 2016 to 2018, 4 billion kilometers of cables have been deployed, which is quite remarkable. But the pandemic has further accelerated this process, with the number of people watching visual content online doubling as lockdowns caused education and work to shift to their homes. Although wire deployment rates have increased, they are still not enough to meet current data demands. Reportedly, the need to deploy 10x fiber at 3x speeds is forcing network operators to develop new cable technologies.

micro cable

Microcables are the best solution for faster, denser fiber deployments to meet current and future bandwidth requirements. The technology will enable network operators to install fiber optic cable systems faster than before while reducing labor and equipment costs. These microfiber cables provide the right balance between deployment speed and fiber density.

Microcable is a type of fiber optic cable that has a smaller outer diameter (OD) and cable weight than traditional cables. For example: traditional Unitube drop cables have an outer diameter of about 4-8 mm, while micro cables have an outer diameter of about 2.5 mm or even 1.6 mm.

Microcable designs include stranded loose tube, center tube, and single tube designs. Common to all these designs is light weight, large outer diameter and reduced gum content. Typically, microcables do not have metal or dielectric coverings and therefore cannot be buried directly underground. Miniature cable design suitable for outdoor and indoor environments. The features and advantages of microcable technology are:


Thin appearance
Guan Xiao
Holds more fiber per tube
200um optical fiber
IBR functional area


Optimize and maximize
Cable diameter reduction
Light weight
Easy to operate
Smaller rollers for efficient logistics
Reduce the risk of cable damage

How can we build denser networks faster?

Combining microcable technology and blow-in equipment allows for denser networks to be built at faster speeds. The advantages and challenges are:

Dense urban deployment
Micro ditch green space installation
Expand existing duct space
service isolation
multi-channel pipeline
Reduce service continuity risks
MLT design – longer splice times
Professional setting

Typically, full-size underground cables are installed inside polyethylene ducts, called inner ducts. These inner ducts with a diameter of 25-51 mm are located inside the telecommunications ducting system. When installing micro cables, the matching micro tubes need to be placed first, and then the micro cables are inserted by blowing. These microducts allow for denser microcable installation based on current needs and provide sufficient remaining space for future installations based on future needs.

As 5G and other next-generation technologies develop and capital expenditures change, demand for data will surge, requiring faster and denser fiber deployment. If you do not adapt to changing needs and continue to use traditional cable and traction methods, you will have no chance of meeting future needs. Therefore, microcable technology is the single best solution with all the necessary attributes to meet current and future data and bandwidth requirements.
