Leveraging the Power of XGS-PON Open Architecture with Comtrend and TiBit

Looking for a better way to deliver XGS-PON? Comtrend and TiBit have partnered to create a flexible, open, and scalable solution. Read on to discover how.


In the rapidly evolving broadband landscape, Comtrend has continued to  champion open solutions, challenging traditional closed architecture models that have service provider facing challenges like:

  • Relying on a single vendor solution leaves you vulnerable to supply shortages
  • Being subject to single vendor pricing in a rising-subscription price model
  • Being locked into one vendor’s ecosystem leaves you unable to access competitive options

Comtrend’s answer to these struggles is our commitment to a “Mix & Match Methodology“, an approach that prioritizes viable, current, and flexible solutions. To further enhance our offerings, Comtrend has partnered with TiBit, a revolutionary access solution technology provider. This article explores the benefits of this collaboration and how it is revolutionizing Fiber access through open architecture.

Introducing TiBit: A Game-Changing Access Solution

TiBit stands out as a remarkable access solution technology that has garnered attention and adoption from major Service Providers in the United States. Its innovative SFP+ OLT MicroPlug enables Service Providers to launch and maintain cutting-edge XGS-PON broadband services at a fraction of the cost compared to traditional methods.

The Power of Openness

One of the key differentiators of TiBit is its commitment to openness. Unlike the conventional approach of relying on expensive proprietary OLT Chassis from a single vendor, TiBit offers an end-to-end XGS-PON solution through open architecture. This eliminates the OLT Chassis, removes the limitations associated with closed systems, and allows Service Providers with more freedom and flexibility.

So what are the benefits of an open solution? 


  • Freedom from Vendor Lock-In
    With TiBit and Comtrend’s solution, Service Providers are no longer tied to a single vendor for their XGS-PON deployments. The replacement of the Chassis with the TiBit MicroPlug allows operators to use any switch for deployment, opening up a world of possibilities and multiple vendor options. This freedom from vendor lock-in empowers Service Providers to choose the best components and technologies that suit their specific needs, ensuring a competitive edge in the market.
  • Simplified Network Deployment

    TiBit’s approach simplifies the network deployment process, making it easier for Service Providers to get started. In just four hours, operators can have the TiBit solution up and running, enabling rapid service rollout and reducing time-to-market. The simplicity of deployment and maintenance further minimizes the effort required from network operators. This streamlines operations and maximizes efficiency.

  • Cost-Effective 

    In addition to its flexibility and simplicity, TiBit offers a cost-effective solution for XGS-PON deployments. The low deployment cost associated with TiBit’s MicroPlug and the ability to leverage existing switches helps Service Providers save significantly on infrastructure investments. This cost advantage plays a crucial role in the ever-changing landscape of subscription pricing, allowing operators to offer competitive services while maintaining profitability.

  • Scalable Solution

    While closed systems with an inflexible OLT chassis require thousands of endpoints to offset initial high upfront costs, the TiBit MicroPlug OLT is completely scalable. ISPs can start with just one and scale as they grow. This is ideal for ISPs that are just now entering the fiber deployment stage of their evolution or are seasoned fiber providers interested in exploring a new technology.

They can provide you with a test kit, allowing you to witness the power of TiBit first hand. Experience the simplicity, cost-effectiveness, and freedom that TiBit brings to XGS-PON deployments.
