a: This column lists the number of circuit breakers required on the PDF.

b: The maximum power consumption of the integrated equipment refers to the maximum

power consumption of the cabinet or the maximum heat dissipation capacity of the

integrated equipment. The power consumption of the integrated equipment do not exceed

the maximum power consumption.

In the case of transmission equipment, power consumption is generally transformed into heat

consumption. Hence, heat consumption (BTU/h) and power consumption (W) can be converted to each

other in the formula: Heat consumption (BTU/h) = Power consumption (W) / 0.2931 (Wh).

Power consumption for the typical configuration refers to the average power consumption of the device

in normal scenarios. The maximum power consumption refers to the maximum power consumption of

the device under extreme conditions.

2.2.2 Subrack

The OptiX OSN 6800 takes subracks as the basic working units.

Subracks should be installed in the cabinet with 50 mm spacing above and below to allow

airing. The DC power distribution box in the cabinet supply power to the subrack, and the

subracks has independent power supply.

Structure

Subracks are the basic working units of the OptiX OSN 6800. The subrack of the OptiX OSN

6800 has an independent power supply.

Figure 2-4 shows the structure of the subrack.

The interface area is behind the indicator panel in the upper part of the subrack. Remove the indicator

panel before you connect cables.

 Indicators: indicate the running status and alarm status of the subrack.

 Board area: All service boards are installed in this area. 21 slots are available.

 Fiber cabling area: Fiber jumpers from the ports on the front panel of each board are

routed to the fiber cabling area before being routed on a side of the open rack. The

mechanical VOA is also installed in this area.

 Fan tray assembly: Fan tray assembly contains ten fans that provide ventilation and heat

dissipation for the subrack.

 Air filter: The air filter protects the subrack from dust in the air and requires periodic

cleaning.

 Fiber spool: Fixed fiber spools are on two sides of the subrack. Extra fibers are coiled in

the fiber spool on the open rack side before being routed to another subrack.

 Mounting ears: The mounting ears attach the subrack in the cabinet.

 Interface area: The interface area provides functional interfaces, such as management

interface, inter-subrack communication interface, alarm output and cascading interface,

alarm input and output interface. It is behind the subrack indicator panel.

: houses service boards and supports service cross-connections.

 IU15 and IU16 are also available for the STG.

 Pair slots refer to a pair of slots whose resident boards' overhead can be processed by the

buses on the backplanes. For the two boards in the paired slots, the inter-board

cross-connection can be directly configured, and the cross-connect grooming of services

can be achieved without the cross-connect board. The pair slots support distributed

grooming.

2.2.3 Board

Function Boards

There are many types of functional boards, such as optical transponder boards and optical

multiplexer/demultiplexer boards.

2.2.4 Small Form-Factor Pluggable (SFP) Module

There are four types of pluggable optical modules: the enhanced small form-factor pluggable

(eSFP), the small form-factor pluggable plus (SFP+), the tunable 10 Gbit/s small form-factor

pluggable (TXFP) and the 10 Gbit/s small form-factor pluggable (XFP). Because they are

pluggable, when you need to adjust the type of accessed services or replace a faulty optical

module, you can directly replace it without replacing its dominant board.

2.3 Software Architecture

The system software includes the board software, NE software and the network management

system.

2.3.1 Overview

The system software is of a modular design. Each module provides specific functions and

works with the other modules.

The entire software is distributed in three modules including board software, NE software and

NM system.

The system software is designed with a hierarchical structure. Each layer performs specific

functions and provides service for the upper layer.

The system software architecture is shown in Figure 2-6.

In the diagram, all the modules are NE software except the "Network Management System"

and "Board Software" modules.

2.3.2 Communication Protocols and Interfaces

The Qx interface is used for communication. Complete protocol stack and messages of the Qx

interface are described in ITU-T G.773, Q.811 and Q.812.

The Qx interface is mainly used to connect the mediation device (MD), Q adaptation (QA)

and NE (NE) equipment with the operating system (OS) through local communication

network (LCN).

Issue 03 (2012-03-29)

OptiX OSN 6800 Intelligent Optical Transport Platform

Product Overview

2 Product Architecture

At present, QA is provided by the NE management layer. MD and OS are provided by the NM

layer. They are connected to each other through the Qx interface.

According to the Recommendations, the Qx interface provided by the system is developed on

the basis of TCP/IP connectionless network layer service (CLNS1) protocol stack.

In addition, to support remote access of the NM through Modem, the IP layer uses serial line

internet protocol (SLIP).
