Overview

With large-scale commercial deployment of new services including

3G, IPTV and broadband access and continual growth of data

services, the capacity of metro transport network has become the

bottleneck for service development. Facing nearly exhausted

bandwidth, a gigantic challenge posed to operators is that which

techniques can provide required bandwidth and intelligent

grooming of large granularity services, while taking into account

multi-service access and aggregation capacity, high integration, low

cost and other requirements.

Traditional WDM transmission platform can provide massive

transmission capacity, ultra long haul, powerful service access and

convergence capability as well as telecom-level protection, but the

cost is rather high and the intelligent dispatching capability is still

insufficient. To cater for the above network development trend

and satisfy customers’ requirements, ZTE launches the new-

generation, large-scale, highly-integrated, low cost, intelligent and

green iOTN product ZXONE 8000 .

Customer Benefits

Stable Equipment Performance

ZXONE 8000 product offers 1+1 protection for SNP board, clock

board and power board. ZXONE 8000 CX31/CX51 /CX71 provide

“overall protection” for cross-connection board to improve the

stability of system monitoring.

ZXONE 8000 product provides intelligent heat dissipation

function. FCC intelligent speed regulating heat dissipation

modules are located at the bottom and top layers of the shelf.

Each FCC has built-in speed regulating heat dissipation fans that

support automatic and manual regulation of temperature.

To improve reliability of cross-connection unit, traditional cross-

shelf large-sized cross-connection unit design is not used for

ZXONE 8000 product; the size of the cross-connection unit is

designed totally the same as that of the service access unit, so as

to improve the universality and reliability of cross-connection

unit.

ZXONE 8000 CX31 sub-rack has 4 cross-connection units. As proprietary patent algorithm and coding/decoding technique are adopted, the system can work properly when any two of the cross-connection units are online at the same time.

ZXONE 8000 CX51 sub-rack has 6 cross-connection units. As proprietary patent algorithm and coding/decoding technique are adopted, the system can work properly when any four of the cross-connection units are online at the same time.

Overall protection enables the whole OTN cross-connection

system to tolerate concurrent failure of any two cross-connection

boards. This is an evolution of protection function, more reliable

than traditional 1+1 protection.

Complete Protection Functions

ZXONE 8000 product offers 1+1 protection for SNP board, clock

board and power board, provides overall protection for cross-

connection board, and has mature optical-layer and electrical-

layer protection techniques.

Optical-layer protection technique: link optical multiplex section

1+1 protection, ring network optical channel 1+1 protection,

OPCS and OPMS;

Electrical-layer protection technique: wavelength/sub-

wavelength channel shared protection, wavelength/sub-

wavelength channel 1+1 protection and intelligent Ethernet ring

protection (ESR) based on L2 switching.

All protective switching time meets the requirement of less than

50ms specified by ITU-T.

CapeX Reduction

ZXONE 8000 can realize service interworking and they can use

the same boards so as to provide full of WDM solutions at

different network levels, reduce quantity of spare parts and cut

down TCO of the customers to the fullest extent.

The line side and client side are separated to increase board

integration. The separation of client side and line side can

aggregate various different client-side services to the same line-

side board to share the bandwidth, which effectively increases

bandwidth utilization rate; the boards on the line side and client

side can be combined flexibly so that the spare parts can be

reduced from M × N to M + N (M and N mean client-side boards

and line-side boards, respectively; M, N>2), which effectively

reduces network cost and equipment room space.

OpeX Reduction

The equipment is green and eco-friendly with low power

consumption. It can save 30%-40% power consumption

Data Sheet: 4 ZXONE 8000 Large-Capacity OTN Cross-Connect Product

compared with average level in the industry. For a network

including ten 80-wavelength sites, it can save 328,500 kWh

power every year and reduce 249 ton CO2 discharge.

Product Architecture

ZXONE 8000 has hardware system and network management

software system, which cooperate with each other but work

independently. ZXONE 8000 hardware system includes optical

forwarding platform, service aggregation platform, add/drop

wavelength division multiplexing platform, optical amplifying

platform, protection platform and monitoring platform.

Optical transfer platform

It adopts optical/electrical/optical conversion to implement

conversion between service signal and line signal

wavelength. Line-side signals meet G.692 and G.709

requirements after signal wavelength conversion.

Service aggregation platform

It aggregates multiple low-rate signals to one wavelength,

or disaggregates a high-rate signal on a wavelength into

multiple low-rate signals.

Add/drop multiplexing/de-multiplexing platform

Add/drop multiplexing platform implements add/drop and

multiplexing of line optical signal wavelength. The

equipment can be divided into Fixed Optical Add/Drop

Multiplexer (FOADM) and Reconfigurable Optical Add/Drop

Multiplexer (ROADM) based on the fact whether the

add/drop wavelength is fixed.

Multiplexing/de-multiplexing platform completes

multiplexing and de-multiplexing of line optical signals.

– Multiplexing: coupling multiple optical signals with different wavelength from optical forwarding

platform and service aggregation platform into one fiber for output.

– De-multiplexing: separate line optical signals from optical amplifying platform based on different wavelength channels and send them into different optical forwarding platforms and service aggregation platforms respectively.

Optical Amplifying Platform

It takes consumption compensation for long-distance

transmitted optical signal by optical amplifying. It usually

locates behind de-multiplexing platform, before

multiplexing platform, and at the intermediate position of

line transmission.

Protection Platform

It provides system with network-level and equipment-level

protection.

Monitoring Platform

– Collect, process and report the configuration, alarm and performance information of each platform to the network management system.

– Receive the commands issued by network management system and forward them to the destination card.

– Transmit network management message via designated monitoring optical channel, which supports a rate of 100Mbit/s with a wavelength of 1510 nm.
