2.3.2 Communication Protocols and Interfaces

The Qx interface is used for communication. Complete protocol stack and messages of the Qx

interface are described in ITU-T G.773, Q.811 and Q.812.

The Qx interface is mainly used to connect the mediation device (MD), Q adaptation (QA)

and NE (NE) equipment with the operating system (OS) through local communication

network (LCN).

At present, QA is provided by the NE management layer. MD and OS are provided by the NM

layer. They are connected to each other through the Qx interface.

According to the Recommendations, the Qx interface provided by the system is developed on

the basis of TCP/IP connectionless network layer service (CLNS1) protocol stack.

In addition, to support remote access of the NM through Modem, the IP layer uses serial line

internet protocol (SLIP).

Application of Electrical-Layer Grooming

Three types of typical application are supported by electrical grooming, for detail, see Figure

3-1.

 Passing through on the client side: The services are input from a client-side port of the

local station and are output through another client-side port. This is, the services are not

transmitted through the fiber line.

 Adding and dropping on the client side: The services of the other stations are transmitted

through the fiber to a WDM-side port of the local station, and then are output through a

client-side port, or the client services are input from the local station and are transmitted

to the other station through the fiber.

 Passing through on the line side: The services are not added or dropped at the local

station. The local station functions as a regeneration station and sends the services from

one side of the fiber line to the other side.

3.3 Optical Layer Grooming

Distribution solutions of medium wavelength resource of WDM equipment are as follows:

 Fixed optical add/drop multiplexer (FOADM)

 Reconfigurable optical add/drop multiplexer (ROADM)

The FOADM solution cannot adjust the distribution of wavelength resource according to the

service development.

The ROADM solution realizes reconfiguration of wavelengths by blocking or

cross-connecting of wavelengths. This ensures that the static distribution of the wavelength

resource is flexible and dynamic. ROADM with U2000 can remotely and dynamically adjust

the status of wavelength adding/dropping and passing through. A maximum of 80

wavelengths can be adjusted.

In the case where one link, fiber or dimension fails in the ROADM solution, other links, fibers

and dimensions remain unaffected. This is attributed to three factors: gain locking of optical

amplifiers, service separation and wavelength blocking of the ROADM solution.

The ROADM solution has the following advantages:

3.4.2 10 Gbit/s, 40 Gbit/s, 100 Gbit/s Hybrid Transmission

With the emergence of service requirements, the existing 10 Gbit/s WDM transmission

system may be gradually upgraded to the 40 Gbit/s transmission system. When this occurs,

the hybrid transmission of the 40 Gbit/s and 10 Gbit/s signals becomes very important.

The OptiX OSN 8800 supports hybrid transmission of 10 Gbit/s signals, 40 Gbit/s

non-coherent signals, 40 Gbit/s coherent signals, and 100 Gbit/s coherent signals, and any of

their combinations. Thanks to this feature, the incumbent networks can be upgraded to ones

with larger capacity based on proper system designs of system performance parameters,

protecting operators' investments while addressing the increasing bandwidth demands. Figure

3-4 shows hybrid transmission of 100 Gbit/s, 40 Gbit/s, and 10 Gbit/s signals.
