Recently, Fujitsu announced that the company will build an optical fiber transmission path experiment in a commercial environment, and the 400Gbps transmission distance will be successful
.
Use new fiber optic cables
with reduced fiber loss and fiber non-linearity.
Through the most advanced high-end digital Coherent optical fiber transmission technology, the frequency usage efficiency is improved with partial positive wave and phase multiplexing, and the reception sensitivity is greatly improved
.
In addition, the repeater will reduce optical wave aging through non-linear optical effects, and package digital reverse propagation transportation signal processing technology
.
Combined with high-precision error correction technology, it can compensate for waveform distortion
generated during long-distance transmission.
The 400Gbps fiber signal will be multiplexed into two Subcarriers through 16QAM frequency conversion
.
While using the already installed 100Gbps transmission network, it is possible
to quadruple the capacity of fiber optic lines.
This experiment will test the quality of communication after transmission of the 1,907-kilometer line between Sapporo and Osaka to ensure error-free transmission
.
Fujitsu said that in May 2016, the line transmission was the longest
in the world.
Even if the use of the commercial environment is taken into account, in order to ensure that the transmission distance is long enough, the 100G transmission network that undertakes the basic optical fiber communication network has four times
the current fiber optic line capacity.
Achieve the goal of technical compliance with the replacement of
400G products.
