      Upgrading Legacy Networks Without Replacing Infrastructure Through an Innovative Transceiver

      As we approach the end of 2024, the fiber deployment landscape continues to evolve rapidly. Predictions indicate that the number of fiber-connected properties will increase from 18.7 million this year to approximately 29 million by May 2027.

      This underscores the growing importance of fiber in overcoming connectivity challenges. However, one critical element is often overlooked: legacy infrastructure. As the demand for 100G and beyond increases, upgrading with single fiber solutions becomes a necessity. Yet, operators can’t afford to continually invest in new fiber—sustainable operations require a smarter solution.

      The Current Fiber Landscape

      Technologies like automation and Artificial Intelligence (AI) are no longer far-flung concepts: they’re real, and they’re increasingly being used in a number of key sectors. As a result, operators need the means to enable the latest technologies on the market, without having to constantly uproot and replace existing cables—a costly and time-consuming venture.

      Modernizing networks is essential for supporting initiatives like moving public services online, enhancing institutional efficiency, and improving public welfare. However, current communication networks, including 5G, now require single-mode fiber connectivity which older infrastructure often struggles to support. Operators are left with a choice: embark on expensive retrofit projects, or find a more cost-effective way to upgrade.

      A Game-Changing Innovation

      The QSFP28 100G ZR4L-Bidi transceiver is designed specifically to help businesses upgrade legacy infrastructure without the need for extensive fiber replacement. 

      The key driver behind 100G upgrades is the increasing demand for bandwidth. With this new transceiver, service providers will find it’s much more profitable to add bandwidth within their existing infrastructure, rather than having to use their already stretched budgets for new fiber.

      This is because the new QSFP28 100G ZR4L-Bidi transceiver enables existing 10G fiber networks to operate at 100G levels at distances up to 70km without the need to replace any existing infrastructure., The transceiver comes with a single LC connector interface for network connectivity at minimum fuss.

      The QSFP28 100G ZR4L-Bidi is 100% compatible with all leading Network Equipment Manufacturer (NEM) switches and routers. Our engineering team ensures that each transceiver is programmed for hundreds of NEM platforms, and we conduct thorough system regression testing to guarantee full compatibility with each customer’s unique network configuration. Before any unit is shipped, we test it within the customer’s specific setup, ensuring smooth integration with their operations.

      Supporting Service Providers

      With this extensive process, the QSFP28 100G ZR4L-Bidi allows operators the means to extend the lifetime and reach of networks across the globe without the need for major infrastructure replacement projects. Designed with service providers in mind, especially in instances where a business has acquired another and is looking to integrate older networks into the fold, the solution ensures no overhaul of fiber is required. For alternative network providers with ambitions to consolidate and expand despite a limited budget, they now have the tools to make it happen.

      As part of this solution, we offer a full portfolio of 100G Bidi transceivers, ranging from 10km up to 70km, to meet various customer applications.

      Supporting High-Traffic Scenarios with a Groundbreaking Transceiver

      In today’s data-driven world, the demand for more bandwidth, faster data rates, and longer transmission distances is skyrocketing. Fiber optic technology offers a powerful solution, especially as real-time data delivery becomes critical across industries.

      From data centers to industrial facilities, seamless connectivity is essential for operational success. With 67% of companies using some form of automation to streamline their day-to-day tasks—a concept reliant on real-time data transmission—it’s essential they choose the most suitable solutions to power their networks. To meet these needs, businesses require technologies that enhance existing infrastructure while delivering reliable, high-capacity performance.

      Rising Demand and Emerging Challenges

      As the adoption of high-traffic applications grows, service operators face increasing pressure to support bandwidth-hungry households, businesses, and data centers. From streaming services to data-heavy operations, the need for speed and capacity is greater than ever.

      The rise of AI and Machine Learning (ML) is only adding fuel to the fire. These technologies power automation and real-time data analytics, driving innovation across industries. But they come with a cost—massive amounts of bandwidth. The strain on networks is real, and it’s only getting worse.

      If this infrastructure cannot overcome these new challenges, it will lead to a degradation of network performance, poor user experiences, and lost business opportunities, especially for those offering high-value services. Unfortunately, many existing solutions simply can’t handle the load. It’s clear that more advanced solutions are needed to overcome these issues. 

      Introducing the QSFP28 100G DCO

      To address these challenges, ProLabs is launching the QSFP28 100G DCO transceiver—a solution set to transform the way network services are provided to access infrastructure. Responding to our customer’s needs for a tunable 100G solution, it offers an impressive 80km point-to-point reach without the need for additional amplification, simplifying network architecture and cutting costs.

      What sets the QSFP28 100G DCO apart is its backward compatibility with existing SFF -8636 ports, increasing the available capacity of existing infrastructure. This makes it an ideal choice for high-traffic environments and backhaul, delivering 100G connectivity to access networks in a cost-effective way.

      Advanced DWDM Technology

      A standout feature of the QSFP28 100G DCO is its use of Dense Wavelength-Division Multiplexing (DWDM). This technology boosts network bandwidth by combining up to 96 wavelengths (or colors) of laser light onto a single optical fiber, ensuring fast and efficient communication between hubs and access points. Simply put, it’s designed to handle demanding workloads with ease.

      Tailored Solutions with ProLabs Tuning

      Every transceiver also comes with a ProLabs tuning system, allowing customers to adjust wavelengths in the field to meet specific network requirements. This flexibility empowers businesses to adapt their networks as needs evolve, ensuring optimal performance at all times.

      The ProLabs Advantage

      Our commitment to customer satisfaction is reflected in our rigorous validation process. Each QSFP28 100G DCO is extensively tested with the same Network Equipment Manufacturer (NEM) gear found in customers’ networks, ensuring seamless compatibility. And if something goes wrong? Our dedicated engineers provide 24/7, 365-day support to get your network back on track quickly.

      The QSFP 100G DCO isn’t just another transceiver—it’s a solution designed to handle high-traffic environments and simplify network upgrades. Preorders are open now for businesses looking to boost connectivity and stay ahead of demand.
