What is the Service Mapping of Huawei OSN8800 Equipment?

Mapping Client Services into ODUk Signals

This section describes how the OptiX OSN 8800 maps services into ODUk signals. WDM equipment uses standard mapping procedures or timeslots to map signals into ODUk signals.

• When using the standard mapping procedures, Huawei OptiX OSN 8800 directly maps signals into ODUk signals and supports flexible grooming of services.
• When using timeslots, the WDM equipment can aggregate multiple services at rates lower than 1.25 Gbit/s into one ODU0 signal, or multiple services at rates lower than 2.5 Gbit/s into one ODU1 signal. This function enables multiple services to share the same ODU0 or ODU1 bandwidth.

Mapping Client Services Using Standard Mapping Procedures

The OptiX OSN 8800 can map client services without using timeslots. It can use standard mapping procedures to map client services directly into ODUk signals, as shown in Figure 1.

Figure 1 Mapping client services into ODUk 

Mapping Client Services Using Timeslots

The OptiX OSN 8800 divides an ODUk (k = 0, 1) signal into several timeslots, each with a bandwidth of 155 Mbit/s. It slices client services into 155 Mbit/s signal segments, each mapped into ODUk signals. The OptiX OSN 8800 can map multiple low-rate client services into one ODUk (k = 0, 1) signal, thereby improving bandwidth utilization.

The services that can be mapped into one ODU0 by OptiX OSN 8800 using timeslots include the following: FE, FDDI, ESCON, SDI, DVB-ASI, FC100, and FICON. Figure 2 shows how FE/FDDI and ESCON/SDI/DVB-ASI services are aggregated into one ODU0.

The services that can be mapped into one ODU1 by the OptiX OSN 8800 using timeslots include the following: FE, FDDI, STM-1, OC-3, ESCON, SDI, DVB-ASI, STM-4, OC-12, FC100, FICON, GE, HD-SDI, FC200, and FICON Express.Figure 3 shows how GE, STM-1/OC-3, and FC100 services are aggregated into one ODU1.

Multiplexing and Mapping ODUk Signals into OTUk Signals

This section describes the structure that the OptiX OSN 8800 uses to multiplex board TN12M4001

 and map ODUk signals into OTUk signals. After the E/O conversion, the signals are sent to the WDM side.

The OptiX OSN 8800 can multiplex and map client signals into ODUk (k= 0, 1, 2, 2e, 3, 3e, 4, flex) signals and produce OTUk (k=1, 2, 2e, 3, 3e, 4) signals on the WDM side for line transmission. Figure 1 shows the ODUk multiplexing and mapping structure that the OptiX OSN 8800 supports.

Huawei Launches the World’s First Fully Outdoor WDM Product

Carrying LTE/LTE-A CPRI services and helping to drive down network costs, making baseband unit cloud a reality
Huawei released the world’s first fully outdoor Wavelength-division multiplexing (WDM) product at a TDC and Huawei joint global WDM/OTN seminar themed ‘Simplified Network for a Better Experience’. Used for carrying LTE/LTE-A common public radio interface (CPRI) services, the product helps drive down the costs of network deployment and operations and maintenance, realizing the baseband unit cloud (BBU Cloud).
In order to reduce site leasing fees and centrally manage base station resources, carriers are beginning to adopt the BBU Cloud as the mainstream networking mode. To date, the baseband units (BBUs) have been collectively deployed in the integrated central office, and remote radio units deployed at the coverage points. The BBUs then work with the remote radio units through CPRIs to extend the service transmission distance. Usually, the CPRI services are transmitted through connected optical fibers. This type of networking mode consumes optical fiber resources and has low reliability. In addition, there are no supervisory measures for managing fibers, making maintenance difficult.
The fully outdoor Huawei WDM product replaces optical fiber connections with WDM technology. This results in a pair of optical fibers able to withstand more than 100 pairs of CPRI services. Also, the Huawei product reduces network investment and shortens service deployment time, providing a highly reliable network by using a unique delay compensation technology. The product also supports remote performance monitoring and uses a network management system to precisely locate faults. To ensure it is suitable for outdoor use it has a compatible design, supporting 614 Mbit/s to 9.8 Gbit/s (CPRI1-CPRI7) service on the client side. This specific design provides a product suitable for covering high-density and large-capacity metropolitan areas.
Huawei WDM/OTN series end-to-end intelligent optical transport platforms are applicable to the backbone core layer, metropolitan core layer, metropolitan aggregation layer, and metropolitan edge access layer.
