High integration
The sub-rack of ZXMP M720 is only 6RU high and single cabinet
supports 6 sub-racks installation. One sub-rack can provide 14
slots, four sub-racks support 40 wavelengths, resulting in
equipment room space saving and power consumption reduction and
greatly lowering operation & maintenance expense.
Large capacity
ZXMP M720 supports up to 40×10G for DWDM system, 18×2.5G for CWDM
system and modular upgrade.
Transmission capability
ZXMP M720 supports single span transmission up to 45 dB without OEO
processing and multi-span transmission, e.g., 18×22 dB, 14×22 dB,
8×22 dB, 7×30 dB, 3×30 dB without OEO processing for DWDM system.
It also supports typical single span transmission of 80KM and
maximum of 120KM for CWDM system.
Access service type
Services access: STM-N (N=1, 4, 16 and 64), POS (Packet Over SDH),
GE, 10GE, FC, ESCON, FICON and DVB, etc.
Services aggregation: 4×STM-1/ 4-->STM-16; 4×STM-16-->OTU2,
2×GE/1G FC/FICON-->OTU1, 8×GE/1G FC/FICON-->OTU2, 4×2G
FC-->OTU2, 2×4G FC-->OTU2, 24×GE-->10GE with L2 switch.
Three-dimensional traffic grooming
Support 10-degree ROADM, and offer l-level cross-connect
dispatching function;
Support distributed cross connection at granularity of ODU0;
Support L2 switching functions, such as VLAN, QinQ;
Enable agile service scheduling from electrical layer to photonic
layer to enhance network flexibility.
Reliable protection
ZXMP M720 supports control board/ power board 1+1 backup and OMS
(Optical Multiplexing Section)/OCH (Optical Channel) 1+1
protection/sub-λ 1+1 protection. In addition, BPSR (Bidirectional
Protection Share Ring), the core patent protection technology of
ZTE, also used in sub-λ-level, can save wavelength resources
tremendously; ESR (Ethernet Smart Ring) shortens the protection
switching time in ring configuration of Ethernet services. All the
protection switching time is less than 50ms in compliance with
ITU-T/RFC standards.
OCH (Optical Channel) 1+1 protection in some OTU board is also
supported, with the result of OP board saving, slot saving and
investment saving.
Optional OSC/ESC
ZXMP M720 supports OSC (optical supervision channel) and ESC
(electrical supervision channel), which can be selected flexibly to
meet different requirements.
