ODN ( Optical Distribution Network ) Red de distribución óptica

Summary

This tutorial explains the setup of an Optical Fiber Network (FTTH), covering the critical components such as the Optical Line Terminal (OLT) and Optical Distribution Network (ODN). It details the OLT's connections, including the internet feed, VLAN configuration, and optional equipment like TV signal modulators. The ODN section outlines the distribution process through MUFAs and NAPs, showing how the network scales with cables like ADSS. The video emphasizes growth and scalability, recommending larger fiber trunks to accommodate future expansions. Viewers also learn how the system eventually delivers internet and TV services to the final user.

Takeaways

• 😀 OLT (Optical Line Terminal) is the central part of the fiber optic network and is essential for connecting the network to the internet.
• 😀 The OLT needs to be configured with a network administrator device, which can be any brand capable of supporting VLAN (Virtual Local Area Network).
• 😀 Internet input typically comes through a router, which then connects to the OLT via Ethernet or fiber interface.
• 😀 Optional equipment like modulators and transmitters may be required if you're planning to distribute television signals over fiber optic networks.
• 😀 ODF (Optical Distribution Frame) is used to organize and manage fiber connections, ensuring that optical signals are correctly routed and distributed to various parts of the network.
• 😀 The first level of the optical distribution network (ODN) uses a primary cable, typically a high-capacity ADSS (All-Dielectric Self-Supporting) cable, with a minimum of 24 fiber strands to allow for future scalability.
• 😀 When designing the network, it’s important to overestimate cable requirements to accommodate future growth, including the potential to lease fiber strands to other services or businesses.
• 😀 The first-level distribution (or backbone) cable connects to distribution boxes called mufas, which distribute the fiber signal to secondary levels of the network.
• 😀 The second level of the ODN is composed of access network boxes, called nap (access network points), which further split the signal to individual users.
• 😀 Drop cables (single-fiber cables) are used to connect the final optical network terminals (ONTs) at customer locations, delivering the fiber-optic signal directly into homes or businesses.

Q & A

What is the main topic of the video tutorial?

The main topic of the video tutorial is the distribution of an optical fiber network for Fiber to the Home (FTTH), specifically focusing on the Optical Distribution Network (ODN) and the Optical Line Terminal (OLT).

What is the role of the OLT in the fiber network?

The OLT is a critical component in the fiber optic network, acting as the central equipment that connects to the internet service provider and distributes internet data to the external fiber network.

How does the internet connection reach the OLT?

The internet connection comes from the service provider and is passed through an administrator device (typically a MikroTik router) before being sent to the OLT. This administrator device manages the connection, often using VLAN configurations.

What optional equipment can be added to the OLT setup?

Optional equipment includes a fiber interface (SFP) for direct fiber connection to the OLT, and television transmission equipment such as modulators for converting coaxial signals to fiber optic signals.

What is the function of the ODF in the network setup?

The Optical Distribution Frame (ODF) connects all interfaces, such as GEPON, and facilitates the distribution of fiber connections to the external network. It also helps manage fiber connections for future expansion.

What type of fiber cable is recommended for the first level distribution?

The recommended fiber cable for the first level of distribution is the ADSS (All-Dielectric Self-Supporting) cable, with a minimum of 24 fibers. This ensures there are enough fibers for growth and future expansion of the network.

What is the purpose of the Mufa device in the distribution network?

The Mufa device is used for the distribution of fiber at the first level of the network. It connects a trunk cable (e.g., 24 fibers) and splits the signal, distributing it further to other Mufas or devices.

How is the second level of the network different from the first level?

The second level, known as the access network, is focused on connecting users and customers. The fibers split at the first level continue to the second level, where they are further distributed to individual households or business connections.

What is the role of the Nap box in the distribution network?

The Nap box, part of the second-level distribution, contains splitters that allow the signal from a single fiber to be distributed to multiple end-users. It is where the final distribution to individual customers is managed.

What is the 'drop cable' in the fiber optic network?

A drop cable is a single-fiber cable that connects the final distribution point (like a Nap box) to the end user's premises, such as a house or business.
