NTT Com to Deploy 400G in Data Centers

NTT Communications will begin deploying a 400 Gbps optical transmission system in its data centers beginning this month. The system will raise the transmission capacity of NTT Com's core network above 19Tbps per optical fiber, or more than double existing capacity. The company said the 400G rate is achieved by using advanced digital-signal processing technology developed in house. The main features and advantages of the 400G system are as follows: Top-level...

NTT Carriers One Petabit per Second over Single Fiber over 200 km

NTT has demonstrated a record inline optical amplified transmission of 1 petabit (1000 terabit) per second over a 205.6 km single strand of 32-core (light paths) optical fiber. The experimental system used 32-core fiber with a new arrangement of cores to reduce inter-core light leakage, a fan-in/fan-out (FI/FO) device to couple light into the multi-core fiber, along with new digital coherent optical transmission technology. The result aws 31.3 Tbit/s...
