An experimental team consisting of members from Cienna, Telstra and Ericsson, are pushing the boundaries for fiber spectral efficiency with a live demo of 400 Gbps over 61.5Ghz spectrum.

Excerpt from Lightwave Online article…

Ciena (NYSE:CIEN) says that together with Telstra and Ericsson (NASDAQ: ERIC) it has succeeded in demonstrating 400-Gbps speeds over 61.5 GHz spectrum. The company asserts this figure represents the highest spectral efficiency per fiber pair everattained in a live environment, enabling up to 30.4 Tbps bandwidth on Telstra’s Melbourne transmission network. Previously, the highest capacity on record was 25.6 Tbps.

Ciena asserts the demonstration recorded the highest capacity achieved to date, up to 30.4 Tbps per fiber pair. The trail used what the company claims is the world’s first fully programmable coherent modem, which can deliver as much as a three times improvement in data capacity. Telstra has deployed this WaveLogic AI modem in its network, which Ciena says also enables up to a 60% reduction in power per bit versus the modem technology Telstra currently deploys.
