1 System Overview
This chapter introduces the background, architecture, system features and applicable
standards/recommendations. It aims at laying a basis for readers to understand the
equipment.
1.1 System Background
The ZXMP M600 is the metro CDWM system developed by ZTE. It features large
optical transmission capacity and can implement transparent transmission of various
services at multiple rates. It can be applied to the convergence and access layers of
large MANs as well as various layers of middle- and small-sized MANs.
In the following, the Metropolitan Area Network (MAN) and Wavelength Division
Multiplexing (WDM) will be introduced briefly.
1.1.1 MAN
As data services such as IP and Ethernet services develop rapidly in recent years, a data
network that can provide wide coverage, high-speed bandwidth and convenient
services is required for providing services such as Internet access, IP-based virtual
private network, IP phone, multimedia application and e-commerce. Meanwhile, as a
metropolis features prosperous economy, dense population, compact coverage area and
frequent information exchange, the information-oriented construction keeps developing
rapidly. Thus, the requirements on MAN also becomes higher and higher.
1.1.1.1 Concept
Generally a MAN is considered as a broadband network that has a unified protocol and
connects government departments, educational and scientific institutions, companies
and home users. It provides data services as well as integrated multimedia services
such as packet voice, graphic and video services, and covers local public networks in
metropolitan and suburb areas.
Based on the statistics and packet technology, the MAN boasts of a clear network
structure, perfect expandability and high reliability. The products and technologies

adopted in it are widely used for commercial purposes, while the user and service
management is flexibly and convenient. The MAN features broadband capacity and
rate, efficient transmission of information and diversified access methods. It obtains the
contents locally, offers user-defined access, provides characteristic services and can
deploy new services quickly. In addition, its capacity can be expanded flexibly and its
upgrade and development can be predicted.
1.1.1.2 Basic Structure
The MAN can either be divided vertically or horizontally:
1. Vertical division
The MAN can be vertically divided into the access layer, convergence layer and
core layer.
The access layer accesses different types of subscribers such as routers and LAN.
The convergence layer converges sporadic access points, implements data
multiplexing, transmitting and switching, and provides traffic control and user
management functions. It includes Multi-Service Transmit Platform (MSTP) and
Metro OADM. The core layer implements high-speed information exchange on
the whole network as well as interconnection between backbone networks. It
generally consists of OADM equipment.

2. Horizontal division
A MAN can also be horizontally divided into the service layer and transmission
layer.
The service layer can implement multiple services such as narrowband voice
service, Internet service, remote calculation and transaction processing,
e-commerce, video conference, multimedia integrated information service,
remote communication and control through computer and leased line service. It
consists of various ATM and IP devices. The transmission layer indicates the
metro optical network that carries the services at the service layer. It provides an
efficient and a unified transmission platform that features large capacity and low
cost and consists of WDM and SDH devices.

1.1.1.3 Features of Metro Optical Network
1. Large service access capacity
The rapid development of MAN service causes the acute increase in the demand
for bandwidth. This demand can only be met by large-capacity metro optical
network. Thus, the core layer of the metro optical network should have large
service access capacity and should be capable of continuous upgrading.
2. Multi-service convergence and transparent transmission
To make full use of the existing network resources, the core layer should be able
to converge various low-rate services and encapsulate services of different rates
and with different protocols into a single wavelength. This helps save the
wavelength resources and economize network construction. On the other hand,
to avoid extra overhead due to protocol conversion and frame format matching
and to make full use of the bandwidth resources, the core layer is also required
to transmit the carried services in the original mode.
3. High reliability and powerful network protection capability
The network security and reliability guarantee normal service transmission.
Thus, redundancy protection measures should be provided for the hardware on
the equipment. Besides, channel protection and multiplex section protection
should also be provided at various levels on the network.
4. Low networking cost
1.1.2 Wavelength Division Multiplexing Technique
As MAN services become increasingly abundant, the requirement on the MAN
capacity becomes higher and higher. As a result, the multi-service broadband MAN
gradually becomes a hotspot in the telecom and network construction. To use the
existent optical fiber resources to increase the bandwidth capacity, the Wavelength
Division Multiplexing (WDM) technique is adopted in the MAN.
WDM can be divided into Dense Wavelength Division Multiplexing (DWDM)
technique and Coarse Wavelength Division Multiplexing technique.
1.1.2.1 DWDM Technique
The DWDM technique adopts an Erbium Doped Fiber Amplifier (EDFA), a high
wavelength stability laser and dense wavelength division multiplexing/ demultiplexing
