2 Performing Hardware Loopback on SiteManually perform loopback to a physical port (optical port) with a fiber.

Tools, Equipment, and MaterialsOptical power meter, fixed attenuator, fiber jumper

Precautions

NOTICEWhen you perform hardware loopback, add an optical attenuator according to the range of theoptical power received by different boards.

ProcedureStep 1 Before a hardware loopback, use an optical power meter to measure the optical power of the

output optical port (OUT).Step 2 Based on the received optical power range of boards, select a proper fixed attenuator. For details

about the range of each board, see the Hardware Description.Step 3 Use fiber jumper to connect the output optical port to the input port on the board, to perform a

loopback.----End

3 Disabling Service-Affecting SettingsAutomatically

This section describes how to disable the service-affecting settings automatically. Service-affecting operations, such as loopback and laser shutdown, can be automatically disabled. Thatis, when the time for performing a service-affecting operation exceeds a certain period, theoperation is disabled automatically.

PrerequisitesYou are an NMS user with "Maintenance Group" authority or higher.

Impact on Systeml If a port is the only way that an NE communicates with the U2000, performing loopback

or laser shutdown at the port will result in loss of communication. Before performingloopback or laser shutdown, you must set automatic disabling for this NE. Otherwise, afterthe communication is lost, you cannot use the U2000 to log in to the NE to disable loopbackor laser shutdown.

l The IPA function is used to shut down lasers on OA boards and Raman boards when a fiberis cut, so as to avoid personal injuries. For security reasons, Auto Disabling for IPADisable can only be set to Enabled.

l Disabling service-affecting settings automatically does not apply to WDM-side lasers onthe PID board.


Background Informationl Service-affecting operations which can be automatically disabled include VC4 Loopback,

Laser shutdown, WDM Channel Loopback, SDH Optical/Electrical InterfaceLoopback, Ethernet Loopback, and IPA Disable.

l After you click Operation Type, and set Auto Disabling to Enabled, you can set AutoDisabling Time(min) as required. The value of Auto Disabling Time(min) for IPA

4 Checking Fiber Jumpers by Using an OpticalPower Meter

This section describes the basic method for checking a fiber jumper by using an optical powermeter during the detection of faults or the commissioning.

PrerequisitesThe light source must exist and the transmit optical power must be stable.The checked fiber does not have services or services are interrupted.

Impact on SystemDuring the test, the services in the tested fiber are interrupted.

Tools, Equipment, and MaterialsFiber jumper, optical power meter, optical fiber extractor, light source

Precaution

DANGERLaser is dangerous. The light is not visible to the eyes with or without laser protective glasses.Do not look into optical connectors or ports. Failure to follow this warning can cause damageto the eyes, or even blindness.

CAUTIONWear a well-grounded ESD wrist strap whenever you touch any equipment. Make sure that thewrist strap fully touches your skin. Insert the connector of the ESD strap into the ESD socket inthe subrack.

PrerequisitesYou are an NMS user with "Maintenance Group" authority or higher.The correlative board must be created.

Impact on SystemNone.


Background InformationFEC is the short for forward error correction. The optical signals undergo quality degradationduring transmission, which may lead the receiver into misjudging "1" for "0" signal or "0" for"1" signal. The FEC adds the parity bits during coding by the transmitter so that the receiver cancorrect the error bits in the code stream by calculating the parity bits.

15 Querying the FEC ModeThis section describes the basic method for querying the FEC type. There are two FEC types:FEC and AFEC.




Background InformationThe OTU board or line board uses FEC and AFEC (Advanced FEC) technology to perform thefollowing functions:l Decrease the requirements on the receiver optical signal-to-noise ratio (OSNR) in order to

extend the transmission distance between optical amplifiers or between REGs.l Provide a greater system margin and guarantee a lower BER rate in the line transmission

to improve the quality of service (QoS) in the DWDM network.The AFEC is a new error correction technique. It adopts two-level encoding, increases encodinggain, and equally distributes the burst errors. AFEC is more powerful than FEC.

Querying the FEC Mode1. In the NE Explorer, select the desired board and choose Configuration > WDM

Interface from the Function Tree.2. Click By Board/Port(Channel). Select Channel from the drop-down list.

Impact on SystemWhen mode of the FEC selected for the upstream board is inconsistent with mode of the FECselected for the downstream board, the services may be interrupted.


Background InformationThe boards with different FEC mode cannot interconnect with each other. For example, the FECmode of the LSX is FEC by default, but it can also be set to AFEC. Though the rates of the twoFEC mode are the same, the boards with different FEC mode still cannot interconnect due to thedifference in FEC mode. Hence, ensure that the FEC types of the upstream and downstreamboards are the same.

Setting the FEC Mode1. In the NE Explorer, select the desired board. In the navigation tree, choose

Configuration > WDM Interface.2. Click By Board/Port(Channel) and select Channel from the drop-down list.3. Click the Advanced Attributes tab. Double-click FEC Mode of the desired optical port
