SFP Module Types Explained Short-range, long-range, extended-range, BiDi, CWDM, and DWDM optics. The Foundation of Every Fiber Link Every optical network — from a campus backbone to a hyperscale data center — depends on the silent precision of its transceivers. SFP modules convert electrical sig...

It’s not just uptime. It’s lifetime. Signal, Reliability, Clarity, and Trust.     Every brand has a logo. Few have a language.For TenFourOptics (TFO), GreenLights4Life is a full system built on three symbols understood around the world: The Green Light — hardware confirmation The Thumbs-Up —...

Critical Minerals in the Data Center How Rare Earths and Specialty Metals Shape Network Infrastructure     Summary: The modern datacenter relies on more than just silicon. It runs on critical minerals — a group of rare and specialty materials that power everything from fan motors to optical lase...

  Why Transceivers Fail in the Field — And How TenFourOptics Solves It Before Shipping A fiber optic transceiver shouldn’t be the weakest point in your network. But it often is. Whether you’re turning up a core switch, building out a datacenter, or chasing a client deadline, a transceiver failure...

TFO Blog 400G Makes Headlines — But 10G, 40G, and 100G Still Rule the Ground Game Summary: While the optical industry is focused on the evolution of 400G, 800G, and 1.6T technologies, the reality on the ground tells a different story: most active deployments in 2025 still rely heavily on 10G, 40G...

  Lifespan: How Long Do Transceivers Actually Last? And Why TenFour Optics Are Built to Outlive the Network They're Plugged Into     The Assumption: Replace Modules Regularly In many environments, optics get replaced every 2–3 years—not because they fail, but because that's what the OEM lifecycl...

The copper vs. fiber debate is reaching a turning point. Fiber leads the way in 2025 and beyond due to lower maintenance costs, scalability, and performance. Studies from Corning and Hexatronic confirm fiber is cheaper to maintain long-term, delivers higher speeds, and eliminates issues like EMI and cable bulk. In high-density data centers, fiber port breakout solutions slash costs by up to 85% compared to copper. Governments worldwide are doubling down on fiber through major infrastructure investments, while the SFP transceiver market itself is on track to more than double by 2033.
