NICT hits 450 Tb/s over a metropolitan network
NICT announced a new world record for optical data transmission, achieving 450 Tb/s over a metropolitan network. This record-breaking transmission utilized a 42.4 THz bandwidth, marking it as the widest bandwidth ever used in such a transmission.
Key Takeaways
- NICT achieved 450 Tb/s optical data transmission over a metropolitan network.
- The transmitted signal occupied 42.4 THz of bandwidth.
- NICT says 42.4 THz is the widest bandwidth ever used in this type of transmission.
Why It Matters
This is a concrete capacity milestone for metro optical transport: 450 Tb/s on a metropolitan network using 42.4 THz of bandwidth. For streaming infrastructure, it underscores how far fiber systems can be pushed for high-volume distribution and backbone aggregation, even though the article is limited to a technical record announcement. The key signal to watch next is whether NICT publishes the test configuration and distance details behind the 450 Tb/s result, since those specifics determine how comparable the record is to deployed metro networks.
