TOKYO, Oct 11, 2021 - (JCN Newswire via SEAPRWire.com) - NEC Corporation (TSE: 6701) today announced that it has been contracted by Facebook to build an ultra-high performance transatlantic subsea fiber-optic cable connecting the USA and Europe.Until recently, subsea cable was composed of 16 fiber pairs at most, but today, by using NEC's newly developed 24 fiber pair cable and repeaters(1), a system can deliver a maximum transmission capacity of a half Petabit per second, the highest to date for a long distance repeatered optical subsea cable system(2). International data usage across the Atlantic is expected to expand twenty-fold in the 15 years between 2021 and 2035(3). The region ranks among the highest growth geographies for data traffic demand, bringing ever-greater demands to reduce the cost per bit on subsea cable networks.NEC has been a leading supplier of submarine cable systems for more than 50 years, and has built more than 300,000 km of cable, spanning the earth nearly 8 times. NEC is well-established as a reliable partner in the submarine cable field as a system integrator that provides all aspects of submarine cable operations, including the manufacture and installati...

NEC Qualifies 24 Fiber Pair Subsea Telecom Cable System

TOKYO, Mar 19, 2021 - (JCN Newswire via SEAPRWire.com) - NEC Corporation (TSE: 6701) and its subsidiary OCC Corporation announced today that they have completed full qualification of subsea repeaters and optical cable containing up to 24 fiber pairs (FPs) (48 fibers). This is a 50% improvement in fiber count over the 16 fiber pair systems generally available today. This development allows cable owners worldwide to construct subsea telecom cables with superior traffic capacity while reducing the cost per bit of the wet plant. This approach is fully in line with SDM (Space Division Multiplexing) system architectures. NEC's 24 FP solution not only provides more flexibility to operate in the subsea fiber pair market, it also enables better connectivity in high-density subsea branches.NEC achieved this milestone with minor modifications to its proven repeater and cable designs. Keeping NEC's quadruple pump redundancy in the repeater (established more than 10 years ago) and maintaining OCC's outstanding cabling performance has resulted in cabled attenuations lower than 0.150dB/km. Low attenuation is critical to achieve large spectral efficiency as well as lower power consumption. "As glo...
