� OTN have abundant overhead bytes
Confidential Information of Huawei. No Spreading Without Permission
� The figure shows the overall electrical layer overhead, include frame alignment overhead,
OTUk layer overhead, ODUk layer overhead, and OPUk layer overhead.
� The frame alignment overhead is used for the framing. It is composed of 6-byte frame
alignment signal overhead FAS and 1-byte multiframe alignment overhead MFAS.
� OTUk layer overhead supports the transmission operation function connected through one
or more optical channel. It is composed of 3-byte SM, 2-byte GCC0, and 2-byte RES. It is
terminated at the OTUk signal assembly and dissemble places.
� ODUk layer overhead is used to support the operation and maintenance of the optical
channel. It is composed of 3-byte PM for end-to-end ODUk channel monitoring, 6-level

OpitX NG WDM System Description
� Optical line protection need OLP card after FIU, The OLP aims to protect fibers of the line, which
Confidential Information of Huawei. No Spreading Without Permission
adopts the dual feeding and selective receiving function of the OLP board. This kind of protection is
performed between two sites segmentally for the optical signal that is multiplexed. This makes that
the working path and the protection path of the protected site must adopt the diverse route.
� Client side och 1+1 protection:
� The client-side 1+1 protection of the OTU uses the dual feeding and the selective receiving
function of the OLP/SCS board to protect the OTU board and units after it.
� The client-side 1+1 protection performs the switching based on the client-side ports. And it
has the larger extent of protection that other protection types
� Intra-borad Och 1+1:
� As for the ring networking, the OTU intra-board 1+1 protection uses the separated paths in
the ring to perform the protection, that is, services are transmitted in both the positive and
opposite direction of the ring before arriving at the destination node.
� As for the chain networking, it is much similar to the optical line protection explained in
chapter one in that the diverse route is required to provide between the adjacent sites. We
need to note that in the actual configuration, line fibers of the OTU board that are dually
fed are sent to the eastward and westward lines of the node through different equipment
types: MUX/DMUX and OA. This process is omitted in this figure.

OpitX NG WDM System Description
� The ODUk SPRing protection mainly applies to the ring network with distributed services.
Confidential Information of Huawei. No Spreading Without Permission
This protection uses two different wavelengths to achieve the protection of multiple
distributed services between all stations. Compared with SNCP, multiple services share one
protection channel in the ODUk SPRing protection. As a result, the ODUk SPRing
protection effectively saves resources. Currently, the ODU1-level protection can be
achieved.
� The ODUk SPRing protection applies to ring networks and thus requires the support of a
network protection protocol. The protection adopts dual-ended switching mode, namely,
when the receiving end of the working channel fails, both the receive and transmitting
ends of the working channel are switched to the protection channels.

OpitX NG WDM System Description
� The WSS is the core component. The two types of WSS are MEMS-based WSS and the
Confidential Information of Huawei. No Spreading Without Permission
LCD-based WSS. The WSS cross-connected a wavelength to a multiplexer corresponding
to the designated output port, according to the wavelength routing information. In this
way, the WSS accomplish the wavelength grooming function.
� In the NG WDM system, there are two types of WSS: WSD9 and WSM9. Considering the
optical channel revertive principle, the WSM9 and the WSD9 are the same in the interior
structure and the mechanism. And here, we are talking about the WSD9.
� Firstly, the chromatic optical signal is demultiplexed to monochromatic optical signals in
multiplex channels. The in-built VOAs adjust the power of each monochromatic optical
signal, and then guide each of the monochromatic signals to different optical multiplexer
by controlling the 1 x N (that is N=9 in the figure) optical switch array. Finally, the signals
are multiplexed and output. In this way, we can accomplish transmitting of any
monochromatic optical signal to any output port.
� Compared with the PLC and the WB, the WSS has the following advantages:
� It has better functionality than the WB and the PLC. It can choose a wavelength to be
switched in multiple directions.
� The WSS can be directly used as a DMUX, which can add/drop any wavelength at any port.
Besides, it can also groom optical signals in multiple directions.

� The OptiX OSN 8800 provides grooming on L1 electrical layer. Granularities that can be
Confidential Information of Huawei. No Spreading Without Permission
groomed at L1 electrical layer are ODU1 signals and ODU2 signals. The electrical layer
processing and grooming are added between the client side interface signals and the
WDM-side interface signals. Thus, the wavelength utilization of the line is improved. In
addition, the OptiX OSN 8800 can connect seamlessly to traditional electrical layer
equipment.
� The OptiX OSN 6800 provides grooming on L1 electrical layer and L2 electrical layer.
� Granularities that can be groomed at L1 electrical layer are GE services, ODU1 signals,
ODU2 signals and Any services. Because the electrical layer processing and grooming are
added between the client-side interface signals and the WDM-side ones, wavelength
utilization of the line is improved. In addition, the OptiX OSN 6800 can therefore connect
seamlessly to traditional electrical layer equipment.
� The OptiX OSN 6800 supports L2 electrical layer switching based on VLAN and Stack
VLAN. The L4G board realizes basic Ethernet management, including management of the
Ethernet private line (EPL) services, Ethernet virtual private line (EVPL) services, the quality
of service (QoS), port basic attribute configuration, and test frames.

OpitX NG WDM System Description
� The OptiX OSN 8800 supports master-slave subrack management. When multiple subracks
Confidential Information of Huawei. No Spreading Without Permission
are used to form an NE, the master-slave subrack mode is required to realize the unified
management.
� This ensures less IP resources. Also the ASON function is realized only in one NE. This
ensures easier maintenance and less management overheads.
� The Main-Slave sub-rack is adopted to deploy the optical layer grooming.
OpitX NG WDM System Description
� The system provides the intelligent power adjustment (IPA) function. When there is a fiber
Confidential Information of Huawei. No Spreading Without Permission
break on the line, the upstream optical amplifier is shutdown to prevent exposed optical
fibers hurting human body.
� In the DWDM system, optical fiber break, equipment failure or optical connector removal
may lead to the loss of optical signals on the main optical channel and on the optical
auxiliary channels. To prevent exposed optical fibers hurting human body, especially eyes,
and to avoid surge of the optical amplifier, the system provides the IPA functions. Where
the loss of optical power signals happens on one or more optical trunk sections on the
main optical channel and the optical supervisory channels, the system can detect the loss
of optical signals on the link and instantly shut down the upstream optical amplifier.
� The system provides the automatic level control (ALC) function. When ALC function is
enabled,the increase in the line attenuation in a section causes the decrease in the input
power of the amplifier in that section. Its output power and the input and output power
of the downstream amplifiers remain the same.
� The system provides the automatic power equilibrium (APE). With the APE function, you
can keep the flatness of the optical power of the receiving end and to maintain the OSNR.
OpitX NG WDM System Description
� A stable clock is the basic condition for an NE to function properly. The clock must be

configured according to clock configuration principles, to ensure the stability of the clock.
� Physical clock ensures frequency synchronization, which is the prerequisite for clock
synchronization.
� Physical clock directly uses the features of the physical layer of the synchronous
transmission network. That is, physical clock directly restores clock frequency from the
physical optical signals, to ensure the frequency synchronization between the upstream
and downstream. In this manner, the services can be transmitted normally.
� Table lists the board in the OptiX OSN 8800 I, equipment version, and NM version that
support the physical clock. In addition, the relation between the board type, equipment
version, and NM version are provided.

OpitX NG WDM System Description
� The OptiX GCP is the ASON software provided by Huawei, which can be applied to the OptiX OSN
Confidential Information of Huawei. No Spreading Without Permission
series products to support the evolution from traditional network to ASON network. The GCP
stands for the GMPLS control plane. The GCP complies with the ITU and IETF ASON/GMPLS-related
standards.
� Compared with the WDM network, the transmission network that applies the new ASON
technology shows advantages in service configuration, bandwidth utilization and protection
schemes.
� In the traditional transmission network, the WDM transmission equipment functions as fibers.
Currently, the WDM transmission equipment also carries services. As a result, more requirements
are for the operability of the WDM equipment. The traditional network has the following problems:
� The service configuration is complex and capacity expansion or service provision takes a
long period.
� The bandwidth utilization is of a low rate and low efficiency. In a ring network, half of the
bandwidth should be reserved.
� Just a few protection schemes are available and the performance of self-healing protection
is poor.
� The ASON has been developed to solve these problems. This technology involves signaling
switching and a control plane to enhance its network connection management and recovery
capability. It supports end-to-end service configuration and the service level agreement (SLA).
