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.
ZXMP M720 supports up to 40×10G for DWDM system, 18×2.5G for CWDM system and modular upgrade.
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), 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.
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.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.
ZXMP M720 supports OSC (optical supervision channel) and ESC (electrical supervision channel), which can be selected flexibly to meet different requirements.
