Optical Fiber Cable Laying

Optical fiber cables are the backbone of modern communication systems, providing high-speed data transmission over long distances. Laying an optical fiber cable is a complex process that requires careful planning, skilled labor, and specialized equipment. However, the result is a high-speed, reliable communication system that can support a wide range of applications. Laying Optical fiber cables involves several steps, including engineering surveys, route planning, excavation, and cable installation, jointing, testing and commissioning.

Survey & route Planning

Route planning is the first step in the process of OFC deployment. It involves determining the most efficient and cost-effective path for the cable. This may involve surveying the area, taking into account factors such as terrain, existing infrastructure, and potential obstructions. LTE provides services for detailed engineering surveys and suggests best cost-efficient route for its customers.


Once the route has been determined and finalized with customers, excavation work can begin. This may involve digging trenches or using horizontal drilling techniques to create a path for the cable. LTE teams perform the excavation work carefully to minimize damage to the surrounding environment and to ensure that the cable is properly protected.

Laying/Pulling of Cable

After the excavation work is complete, LTE teams install the cable which typically involves pulling the cable through the trenches or boreholes or HDPE pipes, and securing it in pits using anchors or marker posts. Utmost care is taken while handling the cable to prevent damage, optical losses or cuts.

Jointing, Termination, Testing & Commissioning (JTTC)

Once the cable is in place, LTE teams conduct two-way testing using top-of-the-line OTDR before jointing & Termination, in order to ensure that the cable is free from defects that may appear during laying / pulling of excavation work, and that there are no issues with the signal quality.

Once cables are jointed end-to-end by LTE’s skilled manpower, the ends are terminated in ODFs and again tested using OTDR to ensure that the end to end signal loss is with the limits defined in customer specifications.”
