What is OFC(Optical Fiber Cable)?

OFC stands for Optical Fiber Cable. It is a type of cable that uses light to transmit data, unlike traditional copper cables that use electrical signals. Optical fiber cables are the backbone of modern high‐speed internet, telecommunications, and data communication networks due to their ability to carry large amounts of data over long distances with minimal signal loss.

Professional Statement

We are an authorized sub‐vendor of Reliance Industries, actively engaged in Five major categories of work. With a strong focus on safety, quality, and timely execution, we consistently deliver reliable services across all assigned areas.
We can mention the 5 types of work

  OFC (Optical Fiber Cable) : Laying and Splicing

  NLD (National Long Distance) : providing backbone fiber connectivity across intercity and interstate routes

  LMC (Last Mile Connectivity) : Fiber link from the main network to the end‐user

  FTTH (Fiber to the Home) : Fiber connectivity to residential and commercial customers

  INTRACITY : Manual or machine-based excavation in city areas

  Enterprises : Fiber connection from L2 switch to client premises in a commercial building


Our Achievements as a Sub-Vendor in OFC Projects

We are proud to serve as a sub‐vendor for Reliance Industries, contributing to the successful implementation of Optical Fiber Cable (OFC) projects across 3 States. Our consistent performance, skilled workforce, and commitment to safety have helped us deliver high‐quality results under demanding timelines.

We are hands‐on experience in executing over 500+ optical fiber cable projects across 3 states in India. We specialize in fiber cable laying, splicing, testing (OTDR), termination, and maintenance for telecommunications, broadband, and infrastructure projects. Our team is skilled certified, and equipped to handle both underground and aerial fiber deployments in urban and rural environments with Timely delivery and quality. And also we are completed more than 3000 Kilometre of Trenching and fiber laying work with advanced machine in NLD Projects.
