INTRACITY

In OFC (Optical Fiber Cable) projects, intracity work refers to the deployment of fiber optic infrastructure within a city or urban limits, as opposed to intercity or long-haul OFC which connects cities. Intracity OFC projects are critical for establishing last-mile connectivity, FTTH (Fiber to the Home), enterprise connections, cell tower backhaul, and other urban communication infrastructure.

NLD

In OFC (Optical Fiber Cable) projects, NLD (National Long Distance) work involves laying and maintaining fiber optic networks over long distances between cities, states, or regions. This is a critical backbone infrastructure for telecom operators, ISPs, and government digital connectivity projects like BharatNet in India.

NLD (National Long Distance) refers to the intercity fiber optic network that carries high-capacity data, voice, and video signals across long distances, forming the core/backbone network of telecom infrastructure.
