1.1 Positioning
The OptiX OSN 6800 is used for long haul backbone, area backbones, local networks,
metropolitan convergence layers and metropolitan core layers.
The OptiX OSN 6800 is for area backbones, local networks, metropolitan convergence layers
and metropolitan core layers.
The OptiX OSN 6800 uses dense wavelength division multiplexing (DWDM) or coarse
wavelength division multiplexing (CWDM) technologies to achieve transparent transmission
with multiple services and large capacity.
The OptiX OSN 6800 supports the following networking modes:
Point-to-point network
Chain network
Ring network
MESH network
It may also work with other WDM, SDH/SONET equipment to offer a complete Metro WDM
solution.

1 Introduction
Dynamic Optical-Layer Cross-Connections
Dynamic intra-ring grooming and inter-ring grooming can be realized using the ROADM
board.
Dynamic optical layer grooming can be classified into intra-ring grooming and inter-ring
grooming, or into two-dimensional grooming and multi-dimensional grooming.
Dimension refers to transmission direction. Two-dimensional grooming refers to wavelength
grooming in two transmission directions. Multi-dimensional grooming refers to wavelength
grooming in multiple transmission directions.
Flexible Electrical-Layer Cross-Connections
The equipment supports non-blocking electrical cross-connections, centralized
cross-connections of massive services, and complex networking.
The OptiX OSN 6800 provides two types of electrical grooming.
Integrated grooming of GE services, 10GE services, ODU1 signals and ODU2 signals
Distributed grooming of GE services, ODU1 signals, OTU1 services and Any services
Full Service Access over Shared 10G and 40G Channels
The ODUk sub-wavelengths can be flexibly combined to share 10G/40G line bandwidth for
transmission. This enables uniform carrying of any services over one wavelength and
therefore improves wavelength utilization to a great extent.
Bandwidth is tailored for services. This improves the efficiency of transmission bandwidth
and achieves "zero waste" of bandwidth.
Hybrid O/E Cross-Connections and Quick Service Deployment
Hybrid O/E cross-connections achieve flexible cross-connections of wavelength or
sub-wavelength services. Quick service deployment helps reduce CapEx. On a flattened
network, services are easy to plan, deploy, and expand. Much less time needs to be taken to
provision a service.
High Reliability
The tributary/line separated structure maximizes the return on investment and reduces the
number of spare parts. When service type changes, users only need to replace the tributary
boards but fully reuse the existing line boards. The use of independent line and tributary
boards reduces the number and type of spare parts from N x M to N + M (N, M > 2), thereby
helping operators reduce construction costs.
Rich OAM, Easy Maintenance, and Lower OpEx
The rich O/E overhead information on OTN equipment leads to a more transparent network,
facilitates fault identification, and helps reduce maintenance costs.
The PRBS function enables quick self-check of OTUs, quick assessment of channel
performance, and quick fault identification.
The "5A" auto-adjustment function:

1 Introduction
Automatic level control (ALC) function effectively resolves the problem of attenuation
of fibers operating over a long term.
Automatic gain control (AGC) enables adaptation to transient changes in the number of
wavelengths.
Automatic power equilibrium (APE) enables auto-optimization of OSNR specification of
each channel.
Intelligent power adjustment (IPA) avoids personal injuries (to eyes or bodies) resulting
from laser radiation in case of anomalies such as a fiber cut.
The optical power adjust (OPA) is made to ensure that the input power of the OTU board
and OA board meet the commissioning requirements.
Support monitor channel power, central wavelength, OSNR, and overall optical spectrum, and
also supports remote real-time measurement of optical spectrum parameters.

Functions of modules are as follows:
Optical-layer boards are classified into optical multiplexer and demultiplexer boards,
optical add/drop multiplexing (OADM) boards, optical amplifier (OA) boards, optical

Product Overview
2 Product Architecture
Electrical-layer boards such as OTU, tributary, and line boards are used to process
electrical-layer signals, and perform conversion between optical and electrical signals.
For OptiX OSN 6800, OTU boards and tributary board have the L2 processing
capabilities, and they can add, strip, and exchange VLAN tags, learn MAC addresses,
and forward packets.
As the control center of the entire system, the system control and communication (SCC)
board cooperates with the network management system (NMS) to manage boards in the
system and to implement inter-subrack communication.
The clock board provides system clock signals and frame header signals to each service
board, and synchronizes the local system time with the upstream system time, achieving
clock and time synchronization.
The power supply and fan systems with a redundancy protection design ensure
highly-reliable equipment operation.
The auxiliary interface board provides functional ports such as clock/time input/output
ports, management serial port, alarm output and cascading ports, and alarm input/output
ports.
Inter-board communication and service cross-connections, clock synchronization, and
power supplies are implemented using the backplane buses. Backplane buses include
control and communication buses, clock buses, and power buses.

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 can 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.

OptiX OSN , and OptiX OSN 6800.
The N66B cabinet consists of the rack (main frame), open-close type front and rear doors, and
side panels at the left and right sides.
Cabinet doors and side panels can be disassembled. The front door and side panels have
grounding points. Keys to the front and rear doors of all N63B cabinets are the same.
