If you would like a more in-depth review of what the path forward with 800G pluggable optics may look like may we suggest watching Preparing the Way for 800G: 100G Electrical and 800G Pluggable Optics. —————————————————————————————————————————————————————————————– The creation of the 800G ecosystem has begun. Alpha samples of 800G OSFP modules have been demonstrated and we […]

One of the great challenges facing data communications is matching the silicon bandwidth with the face plate density. Today, switch silicon can process over 12 Tb/s. But getting this off the front panel at a reasonable density is a challenge. One direction is to move to faster Ethernet speeds. A great example of this is […]

Ethernet business services including cell site backhaul, internet access, and all the flavors of virtual private networks are among the most profitable and fastest growing services at many communications service providers. The best operations teams take great care to ensure business services are high quality on delivery to eliminate costly customer disputes. Here’s a list […]

With the move to pluggable coherent optical modules for the first time since 10G, we see client and line side considerations coming together. The most obvious example of this is optical signal to noise (OSNR) and related measurements. For any modules with the potential for use in an amplified system, OSNR becomes the fundamental figure […]

With the emergence of 400G Ethernet we have seen the wide deployment of higher order modulation in client interfaces.  We have moved from the mature NRZ of 100G and below to PAM-4 modulation both optically and electrically. This has allowed 400G links to be deployed for reaches of 10km. But what about applications like data […]

In this Olympic year, the motto Citius, Altius, Fortius (Latin for Faster, Higher, Stronger) seems very relevant to where we are with Ethernet networking. We need faster bandwidth, higher levels of service and stronger performance to push around all those videos of cats—as well as the more serious (and less cute) business traffic. Approximately every […]
