Overview
ZXMP M721 is a member of Metro Edge eOTN solution. It features smart stature, big capability, low power consumption and high reliability

Specification

Advantage
 
High integration

The height of ZXMP M721 sub-rack is only 1RU or 2RU and one sub-rack can provide 8 slots (2RU DC input), 6 slots (2RU AC input), 3 slots (1RU), respectively, which results in space saving, lowers power consumption reduction and greatly reduces operation & maintenance expense

 
Powerful transmission performance

ZXMP M721 supports 40×10G DWDM system, 18×2.5G or 10×2.5G+8×10G CWDM system, and both systems support smooth upgrade    


DWDM system supports multi-span transmission without OEO electrical relay (18×22dB, 7×30dB, 1×45dB etc.)

CWDM 2.5G system supports 28dB transmission, target distance of CWDM 10G system is 80KM
 

Diversity access service type

ZXMP M721 can access any-rate-service (100Mbit/s – 4.25Gbit/s), and supports intelligent cognition, the port supports automatic identification of type of services

Flexible service grooming

M721 supports DSS (Distributed Service Switch platform) based on ODU0/ODU1

Services aggregation: 4-10×Any-rate-service→OTU1, 4-22×Any-rate-service→OTU2

10G-any services convert to OTU2, support single channel, double channels, and integrated protection OTU cards
 

Reliable protection scheme

ZXMP M721 supports control card/power card 1+1 backup and OMS/OCH 1+1 and ODUk 1+1 protection. All the protection switching time of OMS 1+1, OCH 1+1 and ODUk 1+1 are less than 50ms in compliance with ITU-T standards.
 

Optional OSC/ESC

ZXMP M721 supports OSC (optical supervision channel) and ESC (electrical supervision channel) providing flexibility for deployment
