The Benefits of Using Optical Transceivers in Data Centers

Understanding CFP2 LR4 Transceivers in the Electrical-Optical Fiber Industry

Back to List

Today, fiber optic communications have been firmly established. We install networks both in the switched telephone and CATV networks with industry-standard methods, cables, and sometimes architecture. We have fiber to the home in large-scale implementations (FIOS, etc.). We regularly install fiber backbones in office buildings, in fact, sometimes even more than one provider’s network in a building. We extend our cellular network and back-haul almost exclusively on optical fiber. If we are to believe the trade press, this is only the tip of the iceberg regarding what will happen. I do believe this. However, I question the pundits’ estimates regarding timing. I have watched as new technologies were declared “ready for primetime” and then did not live up to the hype. In many cases, the issues revolved around technological hurdles as well as financial ones. When the technologies finally did make economic sense, the large-scale installs occurred. Many times in my career I have seen a market development specialist describe the three stages of technology adoption: Early adopters (usually about 5-10% of the addressable market) want the newest technology right now. (The latest iPhone is a good example.) The majority of users (about 75%) will adopt when they are given a valid incentive such as lower cost or more services. Those who lag the technology curve, (for example, me when it comes to social media) – also known as troglodytes – go to a new technology only when given no other choice. Based on the above breakdown, many of the newest technologies will only see limited success in the short term. However, those steeped in the frontend learning curve will be best positioned to meet the demands of the largest bulk of users who must be given an incentive to install and use the new technology. As I look today at the utilization of passive optical networks (PONs) fiber to the premises and optical drop cables to extend the cellular network, I see that the incentives are mostly cost and convenience. Communities want good broadband access to attract residents and businesses, so they will suffer the time and discomfort to install a new network. In most cases the reason the network is wanted – and valued – is that the client users of the medium (e.g., social media) have made use of higher bandwidth. So the actual incentive is not always for the end-user (you and me), but rather to the merchants and municipalities that want us to spend our money in their locations. Looking at the above assumptions, I would postulate that many of the next-generation technologies will be less likely to invade our lives before we have truly enjoyed the benefits of the present upgrades, which may take advantage of one or two previous generations of optical fiber, cable, and system design. In that vein, I do not see the short-term benefits of some of the newest technologies considering some of the obstacles yet to be overcome: these are both in technology and cost. Some moving-forward technologies include: Ultra-dense wave division multiplexing Multi-core optical fibers (and their connection issues) No truck roll PON provisioning Ultra-high bandwidth fibers That said, I do see many technologies that are well on their way to rapid inclusion in standard systems. This includes technologies such as: Blowing and jetting cable installation Remote line testing Virtual patch panel maintenance systems Pushable cables As you can see from my comments above, I am not picking winners and losers in technology but rather identifying when these various technologies will integrate into our systems. Plus, I’m providing my view on what forces will push that integration.

5G and Beyond: How Dark Fiber Supports the Next Generation of Telecom Carriers

As technology advances, it falls upon the industry to introduce innovative solutions to the market and share the benefits of new products and ideas. Achieving this requires significant teamwork, as various sectors within the tech industry must collaborate to deliver optimal results. This is true for any area of technology, including the partnership between fiber and telecom. With the growing interest in 5G technology, exploring how dark fiber supports telecom carriers in the transition to 5G is becoming more essential. Enterprise-Level Benefits of 5G While 5G has been accessible to American consumers for some time, enterprises are now entering the market at a pace that is expected to outpace consumer use in a matter of years. This shift marks a significant milestone, signaling the readiness of the corporate world to fully leverage the capabilities of 5G technology. With low latency and high potential speeds, 5G is an ideal choice for companies using high-density applications like augmented reality (AR) and the Internet of Things (IoT). Additionally, it paves the way for large-scale rollouts of smart cities and public safety initiatives. On the security front, enterprise-level users can find assurance in the robust security measures that are ingrained in the very core of 5G technology, which comply with industry-standard protocols. As enterprises continue to adopt 5G, the next logical step is to consider the infrastructure that will support this advanced connectivity. Dark Fiber and 5G To fully capitalize on the benefits of 5G, a reliable and scalable infrastructure is essential. Much like its predecessor, 4G, 5G technology is poised to revolutionize connectivity for all end users, both consumer and enterprise alike. For enterprises looking to implement a 5G rollout, dark fiber emerges as a complementary asset that can provide multifaceted benefits to the industry at large. While fiber is widely regarded as the go-to solution for connectivity, dark fiber elevates this standard by offering a suite of specialized advantages. Unlike “lit” fiber, which accommodates multiple clients on a shared network, dark fiber is leased to individual enterprises. This focused approach not only eliminates the congestion and high-traffic issues commonly associated with shared fiber, but also offers a streamlined path for companies seeking robust connectivity. Dark fiber providers have already laid the necessary infrastructure, leaving enterprises with a single action: securing the lease for immediate access to a dedicated, high-performance connection. Designed with performance, scalability, and security in mind, dark fiber is constructed to meet the unique communication needs of each customer. It justifies its value proposition by significantly reducing or even eliminating the need for third-party service providers. In the context of 5G, which demands a robust and resilient infrastructure, dark fiber stands as an invaluable asset. Its inherent privacy features enable the high speeds and low latency that are critical to unlocking the full potential of 5G technology. The Telecom and Dark Fiber Partnership As 5G continues to gain traction, the role of dark fiber in its rollout becomes increasingly vital. This growing importance is expected to fuel industry expansion over the next several years, thereby enhancing the overall infrastructure for enterprises transitioning to 5G. The escalating demands of the telecom sector have already ignited innovation in fiber technology, setting the stage for a harmonious integration of both sectors in the near future. Building on this, as enterprises strategize for their transition to 5G, dark fiber presents itself as a compelling solution. Given the speed and capacity that 5G offers, the privacy and traffic isolation provided by dark fiber become increasingly appealing to large-scale operations, as shown by current industry trends. Dark fiber also serves as a prudent choice for enterprises aiming to future-proof their connectivity. Its lease-based model allows companies to scale their network capabilities without the worry of congestion causing disruption for their users.
