What is symmetrical optical fiber and how does it differ?

Symmetrical fiber optic connection

La symmetrical optical fiber It is an Internet connection technology that provides the same speed for both upload and download data. This means that sending and receiving information happens at the same speed., which is essential in activities that involve two-way data transfer, such as video calls, cloud computing, streaming, or online gaming.

  • Traditional or asymmetric fiber optics: The download speed is faster than the upload speed, which may be sufficient for users who only consume content.
  • Symmetrical optical fiber: Both speeds are equal, eliminating bottlenecks and improving connection stability and efficiency.

For example, purchasing a 600 Mb symmetrical plan means enjoying 600 Mb of speed when downloading and uploading files, ensuring a smooth experience regardless of the type of activity you perform online.

How does symmetrical fiber optic work?

Symmetrical fiber optic operation

Data transmission in symmetrical optical fiber is carried out through light pulses. that travel through glass or plastic filaments, allowing for much higher speeds than ADSL and other copper-based technologies. The key to symmetry is in the equitable allocation of bandwidth between the uplink and downlink channels, resulting in balanced and stable data transfer.

In practice, this is achieved with technologies such as FTTH (Fiber To The Home) and cutting-edge protocols like GPON, which allow fiber optic cables to reach the user's home or business directly. Since there are no copper cable sections, signal losses are minimized, and actual speeds are close to those contracted.

  • Equitable allocation: Bandwidth is distributed equally, eliminating the asymmetry typical of other connections.
  • Use of advanced equipment: Symmetrical fiber routers are designed to handle large volumes of data in both directions simultaneously.
  • Lower latency: The absence of bottlenecks reduces transmission delay, improving real-time applications.

When is it worth hiring symmetrical fiber optics?

Symmetrical fiber is recommended for all types of users, although there are situations and profiles where it becomes essential:

  • Streaming professionals and content creators: For those who stream live on YouTube, Twitch, or similar platforms, upload speed is crucial to avoid losing image and sound quality or experiencing interruptions. Additionally, uploading high-definition videos or editing multimedia content requires a constant flow of data.
  • Video calls and teleworking: With remote work and virtual meetings becoming more common, it's essential to stream quality audio and video, share screens, and upload documents without delay.
  • Online gaming: Online gaming demands minimal latency and full synchronization between devices and servers. Symmetry prevents dreaded lag and enables live streaming from a console or PC.
  • Cloud backup and data synchronization: Backing up files or syncing folders between different devices is fast and efficient. It avoids waiting times and improves information protection.
  • Smart homes: Having security systems, home automation controls, and connected cameras requires stability in both directions for constant data transmission.
  • Developers and IT professionals: Remote control programs, application testing, code uploads to servers, international collaboration, and large file management make symmetrical fiber an essential tool.
  • Online education and training: Educational platforms, virtual classes, webinars, and resource access benefit from stable and fast connections for all users connected at the same time.

Key differences between symmetrical and asymmetrical optical fiber

The main difference lies in the upload speed. In asymmetric fiber, the descent far exceeds the ascent, which limits activities such as live streaming, uploading large files, or teleworking with multiple video calls.

  • Symmetrical fiber: Both speeds are equal. Perfect for demanding environments.
  • Asymmetric fiber: Ideal if you only consume content (downloading, browsing, streaming), but it is insufficient for uploading data frequently or managing many connections in parallel.

All symmetrical fiber is optical fiber, but not all optical fiber is symmetrical. Furthermore, the most basic symmetrical fiber option typically starts at 100 Mb, sufficient for individual use or up to three connected devices. However, for homes or businesses with many users and devices, 300, 600 Mb, or 1 Gbps rates are recommended.

What factors influence the actual speed of your symmetrical connection?

Even if you subscribe to a symmetrical fiber plan, the speed you experience may differ from the theoretical speed due to several factors:

  • Equipment quality: An outdated router or incompatible devices can limit speeds. Modern routers allow you to truly take advantage of connections above 600 Mbps. Improve mobile and Wi-Fi coverage can be key to obtaining maximum performance.
  • Distance and location: Ethernet cable connections ensure better results than Wi-Fi, especially in large homes with obstacles or electromagnetic interference.
  • Wiring type: FTTH (direct-to-home) fiber offers better value than options where the final section is copper.
  • Number of connected devices: A greater number of simultaneously connected devices can share the bandwidth.
  • Internal network configuration: Avoid repeating signals, unnecessary interconnections, or overloading home infrastructure.

It is recommended to perform speed tests to check the actual performance of the connection, preferably by connecting the main equipment directly to the router via a network cable.
