It supports various modulation ways such as
200G PM-16QAM, 200G PM-8QAM and 100G
PM-QPSK to switch freely. These modulation
methods can be applied to different scenarios.
The leading advantages of FiberHome
FONST6000 in terms of high speed-rates is
from the following core technology application:
Multi-dimension modulation technology
Multi-dimension and multi-system modulation
technology can carry multiply bit information,
promote frequency spectrum efficiency, reduce
the baud rate sent by symbol, decrease baseband
bandwidth and related chromatic dispersion
and polarization mode dispersion and lesson
the need for transmission path and optoelectric
device broadband.
OFDM (Orthogonal frequency division
multiplexing) technology
The application of OFDM has the following
advantages:
Sub-band division reduces system’s broadband
requirements for optical communication device
and strengthens the flexibility of choosing
optical device and module; pilot subcarrier
helps to estimate information channel and
phase; promote the use ratio of frequency
spectrum resource; has good extendibility.
Digital coherent receiving
Digital coherent receiving adopts cheap and
mature digital signal processing technology to
promote the feasibility and reliability of data
transmission. The adaptive algorithms of digital achieve a smooth upgrade to 64T so as to
signal processing can dynamically remedy the

After the optical signal
is quantized digital
signal when it finished
photovoltaic conversion
and sampling through
high speed A/D converter,
with signal processing
technology, it can estimate
carrier frequency phase and
the balance and remedy of
linear phase noise.
Forward correction coding
When modulation, checking, balancing and
multiplexing are unable to meet the requirement
for system transmission performance, linear
coding technology can be employed to
further promote system performance. FEC
can effectively improve system transmission
performance, optimize OSNR requirements and
promote signal’s tolerance for path impairment.
FiberHome’ soft decision and LDPC have the
code gain that is very close to Shannon Limit
and it can be realized easily by using parallel
processing. It is also applied to 100Gbit/s optical effectively, making its equipment performance
transmission system.
32T/64T cross capacity, adopt unified cell
crossing core
With 32T intersection capacity, it can
better satisfy the dispatching requirements
for numerous data of network super node.
Using switching core of unified cell, it is of
flexible dispatching and high extendibility.
It can achieve mix access of TDM, ODUk
and Packet service at random proportion
and flexible networking, which can cut
down the equipment’s power consumption
and size
Integrating MPLS-TP function can achieve
data statistical multiplexing. Aggregation of
Ethernet pot, backbone IP+ light synergy
and the comprehensive carrying of private
line L0/L1/L2 greatly lift transmission
efficiency. Integrated equipment
successfully promotes flat network.
Intelligent green platform towards SDN
network
Refined dynamic energy-saving, 20nm leading
chip techniques, efficient power design,
optimized heat radiation structure, partition
of power supply, self-adaptive adjustment of
crossing power consumption can save energy
the best of its kind.
FiberHome’ FONST6000 employs open SDN
structure to control OTN network via flexible
APP to achieve BoD, network virtualization
VTS, IP and light synergy so as to innovate
operators’ business model, speed up the
approval of new business and make network
control and operating & maintenance more
intelligent and convenient.

experiencing drastic changes. Networking is
becoming faster and more simplified. Based on
customers’ demand, FiberHome continues to
make technological innovation. It provides its
users with the most valuable solutions to face
up to industry shift.
