Huawei claims to have added up to 50% more capacity per fiber in an optical transport network, using a technique called Super C-band. This could greatly increase the efficiency and cost-effectiveness of advanced backhaul and fronthaul deployments for 5G and cloud networks. The vendor pointed out that a combination of technologies – higher order modulation, flex grid channel spacing, higher symbol rates and super channels – have been deployed in recent years by the optical industry, to boost spectral efficiency in the C-band to deliver 32 Tbps per single fiber, or 38.4 Tbps in systems supporting the extended C-band. Now Huawei says it has pushed that capacity further, to 48 Tbps per fiber, by developing a new optical amplifier for…
