1. High integration
ZXMP M721 sub-rack is a highly integrated compact iOTN product.Most
of the boards occupy only one sinlge slot.Sub-rack heights are
1RU,2RU,3RU and 6RU,which can effectively save room space and power
consumpiton,thus significantly reducing operating and maintenace
costs and adapting to the requirement for green network decreasing.
2. Powerful transmission performance
40×10G/100G DWDM application, 18×2.5G or 10×2.5G+8×10G CWDM
application and systems smooth upgrade.
DWDM system supports multi-span transmission without electrical
relay (18×22dB, 7×30dB, 1×45dB etc.). 2.5G CWDM can support 28dB
transmission, and 10G CWDM can reach 80KM.
3. Diversity access service type
ZXMP M721 can access any-rate-service (2Mbit/s – 100Gbit/s), and
supports intelligent cognition, the port supports automatic
identification of type of services.
* SDH service, E1,STM-1/4/16/64/256, OC-3/12/48/192, POS.
* Ethernet service, FE, GE, 10GE,40GE,100GE.
* Storage and video streaming service, 1G/2G/4G/8G/10G FC, ESCON,
FICON, DVB-ASI, SD-SDI/HD-SDI/SDI-3G,InfiniBand 2.5G,InfiniBand
5G,InfiniBand 10G.
* OTN, OTU1, OTU2, OTU2e, OTU1f,OTU3,OTU4.
Other service,CPRI option2,CPRI option3,CPRI option4,CPRI
option5,CPRI option6,CPRI option7.
4. Universal switching platform
ZXMP M721 adapts the packet OTN architecture.The brand-new All in
One design can support OTN/Packet/TDM universal switching.It can
implement access,swtiching and transmission of various service in a
unified way.It greatly relieves IP bandwidth pressure and performs
intelligent grooming of IP traffic.Total switching capacity of
switching sub-rack(CX66) is 840Gbit/s at most.
5. L2 Function
ZXMP M721 supports L2 function,8×FE/GE or 4×FE/GE+4×10GE→10GE.
6. APO Function
ZXMP M721 supports APO function based on the OCH layer an the OMS
section.
7. Flexible service grooming
M721 supports DSS (Distributed Service Switch platform) based on
ODU0/ODU1/ODUflex.
Services aggregation: 4-10×Any-rate-service→OTU1,
4-22×Any-rate-service→OTU2.
10G-any → OTU2, support single channel, double channels, integrated
protection OTU cards.
8. Synchronization
ZXMP M721 supports out-band / in-band 1588V2 transmission and
synchronous Ethernet transmission.
9. Reliable protection scheme
ZXMP M721 supports control card/power card 1+1 backup and OMS/OCH
1+1,VC-12 1+1 and ODUk 1+1 protection. All the protection switching
time of OMS 1+1/OCH 1+1,VC-12 1+1 and ODUk 1+1 are less than 50ms
in compliance with ITU-T standards.
10. Optional OSC/ESC
ZXMP M721 supports OSC (Optical Supervisory Channel) and ESC
(Electrical Supervisory Channel) providing flexibility for
deployment.
