HUAWEI OptiX OSN 8800 T64/T32 Intelligent Optical Transport Platform. Product Description - part 2

2.1 Positioning

The OptiX OSN 8800 T32 and OptiX OSN 8800 T64 are mainly applicable to the backbone

core layers. They are also applicable to the core layers and metropolitan convergence layers.

The OptiX OSN 8800 T32 and OptiX OSN 8800 T64 can be used with the metropolitan DWDM

equipment, SDH equipment, and data communication equipment at the backbone layer to

provide a large-capacity transport channel for services and network egresses. The OptiX OSN

8800 T32 and OptiX OSN 8800 T64 apply to the long-distance and large-capacity transmission

of nation-level trunk and inter-province trunk to maximally meet the requirements of large-

capacity and ultra-long haul transmission for carriers. In addition, the OptiX OSN 8800 T32 and

OptiX OSN 8800 T64 provide carriers with a stable platform for multi-service operation and

future network capacity expansion.

The OptiX OSN 8800 T32 and OptiX OSN 8800 T64 use dense wavelength division

multiplexing (DWDM) technologies to achieve transparent transmission with multiple services

and large capacity. It not only provides service grooming at the optical layer on a wavelength

basis by using the ROADM technology, but also provides sub-wavelength grooming based on

ODUflex/ODU3/ODU2/ODU1/ODU0. This improves the flexibility in service grooming and

bandwidth utilization to a great extent.

The OptiX OSN 8800 can interconnect with the OptiX OSN 6800/OptiX OSN 3800/OptiX OSN

1800 to form an end-to-end OTN network. Also, they can interconnect with the OptiX BWS

1600G to form a WDM network. Typically, the OptiX OSN 8800 is applied to the OTN network.

In addition, the OptiX OSN 8800 can interconnect with the NG SDH/PTN or data

communication equipment to form a hybrid network, realizing a complete transport solution.

This is usually applied to the OCS network. Figure 2-1 and Figure 2-2 show the position of the

OptiX OSN 8800 T32 and OptiX OSN 8800 T64 in the overall network hierarchy.

2.2 Product Features

As a one-box product (OTN+OCS), the equipment integrates functions such as WDM

transport, ROADM, 40G, electrical T-bit cross-connection, cross-connections of any granularity

in the range of 100M to 40G, ASON, and rich management and protection.

Transmission Equipment with High Integration and Ultra Capacity

The equipment is of high integration, which enables flexible service configuration. A network

built with the equipment is easy to design, to expand, and to maintain, and requires a smaller

number of spare parts.

The equipment supports access of massive services and centralized cross-connections and

management of the services. This avoids assembly of multiple subracks. The equipment is of

high integration. For example, one PID chip is integrated with tens of photoelectric components

to achieve 12 x 10G transmission.

When used as an 80/40-channel system, the OptiX OSN 8800 supports:

l Service access over one channel of 2.5 Gbit/s, 10 Gbit/s, 40 Gbit/s.

l Transmission of 10 Gbit/s services over a distance of 5000 km, 40 Gbit/s services over a

distance of 2000 km without electrical regeneration.

l Ultra long-haul transmission of 10 Gbit/s services over a 1 x 82 dB single span.

The OptiX OSN 8800 CWDM systems support service access over eight wavelengths. Each

wavelength supports a maximum rate of 2.5 Gbit/s.

The ASIC and PID technologies enable design of a board with high density and help reduce

power consumption of each port. Ultra cross-connections help reduce bridging at many ODF

and also save space in telecommunications rooms.

The OptiX OSN 8800 T32 supports centralized cross-connections through a cross-connect

board. The OptiX OSN 8800 T32 provides one type of cross-connection boards, that is, XCH.

It supports hybrid cross-connections of ODU0, ODU1, ODU2, ODU3, and ODUflex signals,

and supports a 1.28 Tbit/s cross-connect capacity to the maximum.

The OptiX OSN 8800 T64 provides three types of cross-connect boards, that is, XCT, SXH and

SXM. The XCT must be used together with SXH or SXM. The OptiX OSN 8800 T64 supports

hybrid cross-connections of ODU0, ODU1, ODU2, ODU3, and ODUflex signals, and supports

a 2.56 Tbit/s cross-connect capacity to the maximum.

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.

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:

l Automatic level control (ALC) function effectively resolves the problem of attenuation of

fibers operating over a long term.

l Automatic gain control (AGC) enables adaptation to transient changes in the number of

wavelengths.

l Automatic power equilibrium (APE) enables auto-optimization of OSNR specification of

each channel.

l Intelligent power adjustment (IPA) avoids personal injuries (to eyes or bodies) resulting

from laser radiation in case of anomalies such as a fiber cut.

l 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.

Networking and Applications

About This Chapter

The OptiX OSN 8800 T32 and OptiX OSN 8800 T64 support the point-to-point networking,

chain networking, ring networking, and mesh networking. It can be networked with other

WDM and SDH equipment to realize a complete transport solution.

3.1 Basic Networking Modes

The OptiX OSN 8800 supports point-to-point networking, chain networking, ring networking,

and mesh networking. It can be networked with other WDM and SDH or SONET equipment to

realize a complete transport solution.

3.2 Typical OTN Networking

The OptiX OSN 8800 can be jointly used not only with the OptiX OSN 6800 or OptiX OSN

3800 to form a complete OTN end-to-end network, but also with the OptiX BWS 1600G or

OptiX Metro 6100 to form a WDM network. The OTN or WDM network is then used to transmit

the services from the NG SDH/PTN or data communication equipment. In this manner, the OptiX

OSN 8800 T32 and OptiX OSN 8800 T64 implement a complete transport solution.

3.3 Typical OCS Networking

3.1 Basic Networking Modes

The OptiX OSN 8800 supports point-to-point networking, chain networking, ring networking,

and mesh networking. It can be networked with other WDM and SDH or SONET equipment to

realize a complete transport solution.

Different networking modes are applied to different application scenarios. You need to select

the required networking mode according to the service requirements.

Point-to-Point Network

A point-to-point network is the basic application. It is used for end-to-end service transmission.

The other networking modes are based on point-to-point networking mode, which is the basic

network. A point-to-point network is generally used to transmit common voice services, private

line data services, and storage services.

Chain Network

The chain network with OADM(s) is suitable for a scenario where wavelengths need to be added/

dropped and passed through. A chain network has similar service types as a point-to-point

network, but the chain network is more flexible than the point-to-point network. It can be

applicable not only to the point-to-point service but also applicable to the convergence service

and broadcast service dedicated for simple networking.

Ring Network

Network security and reliability are key factors that indicate the quality of the services provided

by network operators. Because of the high survivability, ring network is a dominant networking

mode in MAN DWDM network planning. The ring network has the widest application range.

It can be applicable to the point-to-point service, convergence service, and broadcast service. It

can diversify into complex network structures such as tangent rings, intersecting rings, and ring

with chain.

Mesh Network

A large number of nodes are connected by straight routes on a mesh network. Mesh networks

have no node bottleneck and ensure unblocked services through alternative routes during

equipment failure. In a mesh network, more than one route is available between two nodes. Thus,

the mesh network has high service transmission reliability, and the mesh topology is a

mainstream networking mode for ASON networks. The mesh networking features flexibility

and scalability. It is widely used in ASON networks.

3.2 Typical OTN Networking

The OptiX OSN 8800 can be jointly used not only with the OptiX OSN 6800 or OptiX OSN

3800 to form a complete OTN end-to-end network, but also with the OptiX BWS 1600G or

OptiX Metro 6100 to form a WDM network. The OTN or WDM network is then used to transmit

the services from the NG SDH/PTN or data communication equipment. In this manner, the OptiX

OSN 8800 T32 and OptiX OSN 8800 T64 implement a complete transport solution.

Typical OTN Networking

When working with the OptiX OSN 6800, the OptiX OSN 8800 T32 and OptiX OSN 8800

T64 can form an OTN network or a DWDM ring to transport or add/drop services on the WDM

line. Figure 3-1 shows the typical OTN networking.

3.2.1 WSS Grooming Solution

ROADM in wavelength selective switch (WSS) mode is applicable to intra-ring grooming and

inter-ring grooming.

At a network node, ROADM in WSS mode can freely change the add/drop status or pass-through

status of a wavelength, and does not interrupt a service in the change process. ROADM can work

with tunable lasers to flexibly groom wavelengths.

WSS enables output of any wavelength through any port. A port in WSS mode can be used as

either a port for local wavelength adding or dropping or a multi-directional MS port. WSS can

work with WSS or a coupler to build ROADM, as shown in Figure 3-2.
