Guest BlogSilicon photonics has transformed coherent transmission by continually delivering significant reductions in the power, size, and cost of optical modules. An increasing number of optics vendors today are leveraging this technology for their pluggable coherent solutions. However, this was not always the case. Only nine years ago, many companies were challenging whether silicon photonics was […]
Guest BlogAnyone who has been stuck in congested traffic has felt the pain of too many cars condensed into a finite number of lanes. Adding more lanes to highways can alleviate traffic congestion and ease bottlenecks, but it comes with a hefty price in terms of both dollars spent and commuter headaches. Luckily, solving your network […]
Guest BlogIf you have followed ProLabs social media feeds over the past year, you know that we’ve been present at many service providers conferences around the world. We’ve attended and contributed to SCTE Cable-Tec EXPO, NGON, Fiber Connect, and FTTH Europe to name a few. We’ve witnessed the fiber optic world first-hand and it is in […]
Guest BlogWhat’s the difference between 400GBASE-LR8 and 400GBASE-LR4? Both QSFP-DD and OSFP transceivers can transmit at 400Gbps using 8 lanes of 50Gbps PAM4 or 4 lanes at 100Gbps PAM4. But what’s the real difference behind 50Gbps PAM4 and 100Gbps PAM4? How do we achieve this transition? Pre-requirements Modulation For all optical transceivers transmitting up […]
