HUAWEI OptiX Metro 6100 optical fibre Transmission transceiver
The product supports various optical layer technologies.
The product provides the following wavelength resource allocation solutions: optical signal grooming capability and electrical signal grooming capability.
Optical Signal Grooming Capability
These two solutions are applicable to the OptiX Metro 6100 DWDM systems (DWDM system for short). Only FOADM is applicable to the OptiX Metro 6100 CWDM systems (CWDM system for short).
In a DWDM system, the optical signal grooming that is realized by the ROADM technology is classified into two types:
Two-dimensional grooming (the wavelength grooming in two directions)
Multi-dimensional grooming (the wavelength grooming in multiple directions)
With the ROADM technology and the full-band tunable optical module on the OTU board, the DWDM system realizes the dynamic networking of optical signals, and supports many types of complex networks, such as tangent rings, chain, and intersecting rings. In this way, the system ensures flexible grooming of optical signals in or between networks.
The product supports DWDM and CWDM technical specifications.
Table 2-1 lists the transmission capacity and the upgrade and expansion ability for DWDM and CWDM technical specifications.

Upgrade and expansion
Supporting upgrade of each wavelength of C band at 2.5 Gbit/s, 5 Gbit/s, 10 Gbit/s and 40 Gbit/s rates.
Supporting upgrade of each wavelength at 2.5 Gbit/s rate.
a: This value is based on the scenario where the DWDM system uses only 40 Gbit/s wavelengths to access signals.
b: The maximum add/drop traffic is the add/drop traffic in the OADM station that is formed by back-to-back OTMs. The DWDM system can block and pass through any channel through the DWC board or the WSD9, WSM9, RMU9 and WSMD4 boards. The DWC is the dynamic wavelength control board. The WSD9 is the nine-port wavelength-selective switching demultiplexer board. The WSM9 is the nine-port wavelength-selective switching multiplexer board. The RMU9 is the nine-port ROADM multiplexing board. The WSMD4 is the 4-port wavelength selective switching demultiplexing/multiplexing board. In this way, the system can dynamically add/drop wavelengths to realize the ROADM.
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.
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.
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.
The product can access services of different types by using different optical transponder boards (OTUs).

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.
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.
