HUAWEI оптический приемопередатчик с оптической передачей Metro 6100

Transmission Capacity
The transmission capacity varies with the system type.
A DWDM system can access a maximum of 40 wavelengths. The rate of each can be 2.5 Gbit/s, 5 Gbit/s, 10 Gbit/s, or 40 Gbit/s.
A CWDM system can access a maximum of 16 wavelengths. The rate of each can be 2.5 Gbit/s.
Transmission Distance
The transmission distance varies with the system type.
Transmission Distance Specification in DWDM Systems
According to the type of fibers, the DWDM system uses the forward error correction (FEC), SuperWDM, dispersion compensation and optical equilibrium technologies by option and can support the long haul transmission without an REG.
The transmission distance specifications on the G.652 fiber of the DWDM system are as follows:
When the FEC and SuperWDM (DRZ coding) technologies are used, the systems allow an attenuation of 20 x 22 dB for transmission without an REG.
When 40-wavelength access is used, the DWDM system allows an attenuation of 46 dB for long-haul single-span transmission.
Transmission Distance Specification in CWDM Systems
On the G.652 fiber, the CWDM system allows the 80 km single-span transmission.
Networking Capability
The product provides a variety of networking mode.
The OptiX Metro 6100 supports point-to-point, chain and ring networking modes.
The OptiX Metro 6100 can also be used as equipment for the convergence layer and work with the OptiX Metro 6040 to offer a complete Metro WDM solution.
Integrated System and Open System Compatibility
There are two types of DWDM systems: integrated DWDM system and open DWDM system.
The open DWDM system is configured with the OTU boards to convert a wavelength into a G.694.1-compliant wavelength.
The integrated DWDM system does not need the OTU boards when its client-side equipment (for example, the SDH equipment) has optical transmitter interfaces that comply with G.694.1.
Service Access
The product can access services of different types by using different optical transponder boards (OTUs).
Types of Service Access
The product can access almost all types of services that are rated from 16 Mbit/s to 40 Gbit/s.
Table 2-2 lists the types of the services that can be accessed by the OptiX Metro 6100.

Guaranteed Reliability
The product provides equipment level protection and network level protection.
Equipment Level Protection
The product provides various equipment level protection schemes to enhance the system reliability.
Each board in the OptiX Metro 6100 accesses two external –48 V DC working power supplies. The two power supplies serve as mutual backup. When any of the two fails, the board remains in the normal working state.
Network Level Protection
The product provides various network level protection schemes to enhance the system reliability.
The OptiX Metro 6100 provides the following network protection schemes:
Optical channel protection
Optical line protection
Wavelength cross-connection protection (WXCP)
Tribute protection switching (TPS) and double path protection switching (DPPS)
VLAN SNCP protection
Optical wavelength shared protection (OWSP)
Optical wavelength shared protection (DCP)
There are five schemes for optical channel protection:
Inter-broad wavelength protection
Intra-board wavelength protection
Extended intra-board wavelength protection
Inter-subrack 1+1 optical channel protection
1+1 wavelength protection at client
Configuration Data Backup
The SCC board provides an external storage device to back up network element (NE) configuration data.
It serves to restore the data after the SCC board is replaced.
Performance Monitory of Access Services
The product monitors various performances of the services. This helps in the routine maintenance and troubleshooting.
The OptiX Metro 6100 provides multiple monitoring functions, including:
B1 bit error monitoring
Ethernet performance monitoring
Optical power monitoring
The monitoring covers services on the WDM side and on the client side as well as the converged sub-rate services.
Table 2-5 shows the performance monitoring based on the service types.
Performance monitoring of the accessed services

In-Service Optical Performance Monitoring
The system provides the performance monitoring based on the network.
The optical monitoring interfaces are provided on the multiplexer, demultiplexer, and the optical amplifier of the DWDM system. The optical spectrum analyzer, multi-wavelength meter or MCA board can be directly connected to these interfaces to measure performance parameters at reference points without service loss.
Network Management Tools and Protocols
By using the Qx and CORBA interfaces, the NM system manages alarm, performance, configuration, communication, security, and topology of the entire optical transmission system.
The NM system also provides end-to-end management according to the requirements of the user. The NM system improves the network quality, lowers the maintenance cost, and ensures reasonable utilization of the network resource.
The NM system provides user friendly interfaces and comprehensive functions. Its software system adopts component technology and object-oriented technology so that the application sub-systems can be tailored according to the requirements of the user. This facilitates system expansion.
T2000
OptiX iManager T2000 (T2000 for short) is a subnet management system (SNMS). Subnet management system of the new generation can manage and control NEs and the area network. In the telecommunication management network (TMN) architecture, SNMS is located between the NE level and network level. Therefore, the T2000 supports all functions of NE-level and part of the network-level management functions.
The T2000 provides the users with single-layer management network solutions for small and medium-sized transmission networks. The T2000 can assist network layer management system and service layer management system in managing large-scale transmission networks together with the upper-level network management system (through the standard external interfaces).
Simple Network Management Protocol
The system provides the simple network management protocol (SNMP).
The SNMP is a standard protocol based on user datagram protocol (UDP). With an SNMP compatible management interface, any NM system can query the alarms and performances of the equipment.
Transmission of Network Management Information
There are three communication modes: HWECC, IP over DCC and OSI over DCC.
HWECC: The management information is transmitted by using the HWECC protocol sharing method.
IP over DCC: The management information is transferred by using the IP protocol sharing method.
OSI over DCC: The management transmitted is transferred by using the OSI protocol sharing method.
