We understand the basic composition of a fiber optic cable — core, cladding, buffer — and that there are glass or plastic cores. Both zip light through them, but because this is technology,

As the demand for bandwidth surges, driven by AI, machine learning, and high-performance computing (HPC), 800G optical transceivers have become essential for modern data centers. Both OSFP (Octal Sma

Data center operators continue looking for ways to improve efficiency in all areas. They may be searching for solutions in deployment, cooling, energy, and/or rack space usage. The right Dir

With the emergence of 400G ZR and ZR+ technologies, the data center interconnect (DCI) and metro network market has reached a significant milestone in high-speed connectivity solutions. Thes

Demystifying DWDM for the DCIIn previous articles, we discussed how using passive Dense Wave Division Multiplexing (DWDM) can help network operators achieve very high per-fiber capacity using inexpens

Question: What’s up, PoP? Larry Legg says: A PoP (or Point of Presence) is a collection of equipment that happens to be all in one place. It typically has servers, routers,

The optical communications market remained strong in the second quarter of 2021. Approved Networks (a branch of Legrand) has also seen strong growth across optics, Direct Attach Cables (DACs), and esp

InfiniBandTM has been on the market for more than two decades. Now that there have been new developments in 200G/400G link speeds, it’s worth taking a fresh look at InfiniBand.What is InfiniBand?Accor

In my article How To Build Your 5G RAN Fronthaul, I discussed how to select the right optical transceivers to build your 5G Radio Access Network (RAN) fronthaul. I was asked to expand on

In the past, we have discussed how colleges and universities can add bandwidth to their networks, even when faced with fiber constraints. However, given budget limitations, it may not always

Approved Networks, a brand of Legrand, provides a broad range of direct attach copper cables (DACs) and active optical cables (AOCs). This application note illustrates the use cases in the data center

As data centers evolve and demand for higher bandwidth increases, network architects and engineers face the challenge of building infrastructure that can seamlessly migrate from 10G to 800G. One cr
