In today’s digital world, data transmission is paramount. Companies are constantly innovating to find ways to maximize data transmission using minimal space and incurring minimal losses. Optical fiber cables have become a popular choice for data transmission, as they can provide faster speeds, higher bandwidth capacity, and a more secure connection. Additionally, multiplexing has enabled increased data transmission speeds by allowing multiple signals to be transmitted simultaneously over a single fiber. Moreover, technology such as Wavelength Division Multiplexing (WDM) and Dense Wavelength Division Multiplexing (DWDM) have enabled even greater data transmission speeds, as they can send multiple signals over a single fiber with less power. With the use of these technologies, data transmission has become more efficient, allowing for faster transmission speeds and increased reliability. This has also enhanced modern optical communication, fiber optic communication, and real time network services across data center infrastructure and long distance deployments.

Ribbon cables having high fiber counts are commonly used for high density data transmission. They are typically very cost competitive in high fiber counts as they offer a greater packing density that enables efficient use of limited duct space. In the recent past however, another family of optical fiber cables has started to gain traction for high density data transmission, Micromodule Cables. These small sized, high density designs are increasingly preferred for cloud computing and long term backbone networks.

What Makes Micromodule Cables Different

Micromodule cables are high-density optical cables with several individual micromodules as opposed to loose tubes in conventional cables. The micromodules typically include optical fibers arranged in a sheath for transmitting optical data and are housed in a cable jacket. Micromodule cables are typically designed for outdoor applications and can transmit enormous amounts of data. Micromodule cables offer several benefits that enable them to become noticeable across the telecom industry.They also outperform traditional loose tube cables in many high performance environments.

Key Advantages of Micromodule Cables

• 1) Maximum data transmission: 5G revolution corresponds to innovative product solutions for increased bandwidth. The need for maximum data transmission in minimum space leads to innovative cabling solutions with high density fibers. With single mode fiber supporting long distance communication and lower signal loss, micromodule designs enable efficient optical pathways where light travels with minimal distortion.


• 2) Optimum utilization of duct space:Micromodule cables have lower diameters than traditional underground and overhead cables. Thus, they save the duct space for maximum utilization and are cost effective in the overall project implementation. Their small sized design allows more glass fibers to be packed efficiently while maintaining a stable refractive index profile.


• 3) Ease of Installation:As against PBT loose tube cables, micromodule cables do not require any tools to cut the outer covering and can be peeled through bare nails. Micromodules are kink resistant which makes them an appropriate solution for the closure trays. This not only makes them easier to install but also protects the fiber during handling and long term operation.


• 4) Mid-span access:A unique feature of Micromodule cable is the Mid-span access of fibers. The micromodules can be pulled out of the cable without cutting the cable.

Due to these multiple advantages, these cables are increasingly adopted in more and more countries. Initially, it has gained momentum in France and now gaining widespread acceptance in other parts of Europe like Spain, Germany, and the UK.

HFCL’s Innovation in High Fiber Micromodule Technology

HFCL has continually strived to stay ahead of the curve in terms of technology and product offerings. With the help of its in house Research and Development team, HFCL has developed over twenty micromodule cables suited for various applications including backbone networks, data center deployments, duct and overhead applications. These products have been successfully supplied to prominent customers across the world helping HFCL to stay at the forefront of the industry. This also strengthens the company’s position in fiber optic cable innovation and long distance data transmission.

HFCL has made a significant stride in its ambition to develop high fiber count micromodule cables for the 5G revolution. With its latest breakthrough in 864 fiber count micromodule cables, it has achieved a reduction of 24 percent in cable diameter over conventional cables, making them more space optimized, lightweight, and easier to transport. The faster and easier mid span access with effortless peeling makes them easy to install in fiber distribution and termination units. The cables are also known for their resistance to kinks, UV protection, inhibition to longitudinal water penetration in cables, and being jelly free. This advancement represents a major leap for high fiber and fiber micro module engineering.

The Road Ahead for High Density Fiber Networks

Due to all these features, these cables are highly suitable for backbone, access, and distribution networks with typical installation within ducts. With the successful development of 864 fiber count micromodule cables, HFCL has now set its sight on achieving 1000 plus fiber count within the micromodule family soon. As demand for data transmission and data center scalability grows, such innovations support long term reliability and superior network performance
