Huawei OptiX BWS 1600G. Technical Description - part 3
1 Overview
1.5 Network Management System
Huawei NM is able to manage not only DWDM equipment, but also the entire
OptiX family members including SDH and Metro equipment. In compliance with
ITU-T, NM offers rich network maintenance functions. It can manage the fault,
performance, configuration, security, maintenance and test of the entire OptiX
network. It also provides the end-to-end management function according to the
requirements of users. It improves the quality of network services, reduces the
maintenance cost and ensures the rational use of network resources.
NM with friendly Man-Machine interfaces, powerful and state-of-the-art
functionality, is used in OptiX BWS 1600G system. Its object-oriented design
allows the user to enable or disable any service according to the physical network.
In an OptiX BWS 1600G network, NM provides many functions, such as:
End-to-end channel (wavelength) management
Wavelength resource statistical analysis
Terminal simulation program
Alarm management
Performance management
System management
Equipment maintenance and management

2 Product Description
provided as mutual backup to each other. It also provides 16-channel external alarm
input interfaces and 4-channel cabinet alarm output interfaces, easing the
management of the equipment.
The OptiX BWS 1600G cabinet has the following features:
The cabinet leaves much space for routing and managing optical fibers.
Two movable side doors are installed at both sides of the cabinet. Each side
door can move in or move out along the top and bottom slide rails.
Air vents are provided at the front door of the subrack, the rear door and
upper enclosure frame of the cabinet to ensure heat dissipation.
For the structure of the cabinet, see Chapter 1 "Cabinet" in OptiX BWS 1600G

2.2 Subrack
2.2.1 Structure
The OptiX BWS 1600G subrack is divided into four areas. The upper part is the
interface area where all kinds of electrical signals are accessed. The middle part is
the board area where DWDM boards are installed and the lower part comprise the
fibre cabling area & fan tray assembly area. The structure of the subrack is shown in
Figure 2-1.

Figure 2-1 OptiX BWS 1600G subrack
Interface area
All external interfaces are located in this area, including the interfaces for subrack
power supply, NM, orderwire telephone, and so on.
The interface area also works as a heat dissipation outlet of the subrack. A beam (a
solid metal sheet) is placed at the top of subrack to fix the orderwire phone.
Board area
Totally 13 board slots are available, numbered IU1, IU2, IU3, … IU13 from left to
right when you face the front surface of the subrack. Slot IU7 is for the SCC/SCE
board and is 24 mm wide. Other slots are 38 mm wide. All optical ports are located
on these front panels. Most optical ports are of LC/PC type while the "LINE",
"EXT" and "OUT" optical ports on the front panel of the Raman amplifier unit and
"OUT" port of the HBA board are of LSH/APC type.
Fibre cabling area
2-3
2 Product Description
All the optical fibres from the optical ports are routed to this area. These optical
fibres then come out of this area and reach the corresponding side of the subrack.
There are fibre spools at the two sides of the subrack, allowing good management
over the optical fibres.
Mechanical variable optical attenuator (VOA) is installed here.
Fan tray assembly
This area contains a fan tray and an air filter. The air filter is fixed beneath the fan
tray. The fans and the air filter ensure that the equipment works in a dust-free and
normal temperature environment.
Front door
The front door is intended for equipment protection and EMC. The inner side of the
front door is equipped with hooks to hold the screws for adjusting the mechanical
VOA.
Fibre spools
They are used to coil the slack of the optical fibre.
