100G performance
100Gb/s system adopts PM-QPSK modulation to support SD-FEC
technology with good OSNR tolerance. Industry's most advanced DSP
processing technology can support 60ps of PMD tolerance and
+/-70,000ps/nm of chromatic dispersion tolerance. Transmission
distance can reach over 5,000 kilometers without electrical relay,
which saves the investments and facilitates the maintenance.
Three-dimensional traffic grooming
Support 2-9 degree ROADM, and offer l-level cross-connect
scheduling function;
Support centralized cross connection at granularities of
ODU0/1/2/2e/3/3e2/4/flex.
Support L2 switching functions, such as aggregation, VLAN, QinQ and
L2 QoS.
Enable any service scheduling from electronic layer to photonic
layer to enhance network flexibility.
Self-adaptive multi-service access
Support the client supports 100M-100G any service access: the
access of STM-N, FE/GE/10GE/40GE/100GE, OTU1/2/3/4, DVB, ESCON and
FC services.
The universal service access board enables hybrid transmission of
the operator's multiple services.
Complete network protection
Provide perfect photonic layer and electronic layer protection
schemes, in which, the unique and patented path shared protection
technique realizes higher system wavelength utilization and lowered
network construction investment.
Photonic layer protection: path shared ring protection, multiplex
section shared ring protection, sub-network connection protection,
1+1 multiplex section protection, optical line protection.
ODUk layer protection: ODUk sub-network connection protection, ODUk
shared ring protection.
L2 protection: ESR Ethernet ring protection.
Highly reliable system architecture
Provide 1+1 backup for main control unit, power module unit,
cross-connect unit, and common interface unit, and adopt high
reliability design at sub-rack level and cross-sub-rack level.
