Method 2

Use the SMARTKIT inspector to query all optical modules. Manually collect information about vendor PN, transmit optical power, and enclosure temperature in the query results, as shown in Figure 2.

Characteristics of the involved optical module: The temperature is higher than 60 degrees, the transmit optical power is not in the range from 1.5 dBm to 5 dBm, the vendor PN is SPS4348HHPCDE, and the vendor is SOURCE PHOTONICS.

Information collection in the query results

Select the two check items as shown in the Figure 3.

Inspection template configuration

[Root Cause]

Some optical modules may rarely become faulty after long-term working at high temperature, resulting in unstable transmit optical power.

[Impact and Risk]

When the problem occurs, corresponding ONUs are offline. According to the vendor, 0.143% of the optical modules may become faulty at high temperature.

[Measures and Solutions]

Recovery measures:

Perform the following steps to cool the enclosure of the involved optical module.

Tune down the temperature in the equipment room.

If dust on fans or subracks results in weak heat dissipation capacity, urge customers to clear the dust. For details, customers can refer to corresponding product documentation, such as the MA5600T&MA5603T V800R011C00 Product Documentation 03.

Manually accelerate the rotating speed of fans. (Long-term high-speed rotation shortens the useful life of a fan, so this solution is just a temporary solution.) Setting examples are as follows:

For V800R005/V800R006/V800R007/V800R008:

MA5600T(config)#interface emu 0 

MA5600T(config-if-fan-0)#fan speed mode manual 

MA5600T(config-if-fan-0)#fan speed adjust 5

For V800R009/V800R010/V800R011/V800R012:

MA5600T(config)#diagnose 

MA5600T(diagnose)%%fan speed mode manual 6

The digit in red in the command indicates the rotating speed level of the fan (the highest levels for V800R008 and V800R011 are 5 and 6 respectively), the higher the digit, the faster the rotating speed. It is recommended to tune up the rotating speed to the maximum, and then gradually tune it down. Long-term high-speed rotation shortens the useful life of a fan. Therefore, exercise caution when adopting this solution.

Preventive measures:

Use the preventive maintenance inspection tool to check the enclosure temperature of optical modules on the live network. For the site where the enclosure temperature of optical modules is higher than 60 degrees, urge customers to improve equipment room environment. The recommended temperature is about 23 (±1) degrees.

Solution:

When the problem occurs, perform the recovery measures to cool involved optical modules, and then perform the following steps based on actual situations:

If the problem is solved, the optical module can be used but not used at high temperature.

If the problem persists (the hardware of the optical module is faulty), use a spare part to replace it. A small number of faulty optical modules can be directly sent to Huawei for repair based on the specified procedure. A large number of faulty optical modules are handled by corresponding regional service contact personnel.

[Warning Conditions]

The warning does not take effect when the trigger conditions are not met.

How to Configure 2 Multicast Vlan in order to watch IPTV through only one service-port

When we need  to configure two Multicast VLAN for IPTV service, that is to say, one VLAN to SD channels and another VLAN to HD channels, we have a problem, in service-port we can configure only one VLAN, so we can watch only SD or HD channels.

The following is BTV configuration in MA5603T

btv
igmp user add service-port 4 no-auth
multicast-vlan 92
  igmp version v2
  igmp multicast-vlan member service-port-list 4
  igmp mode proxy
  igmp program add batch start-index 0 ip 239.0.4.2 to-ip 239.0.4.145 hostip  10.146.34.233

  igmp program add batch start-index 144 ip 239.0.40.185 to-ip 239.0.40.224 hostip 10.146.34.233

  igmp uplink-port 0/6/0

multicast-vlan 80

  igmp version v2

  igmp mode proxy

  igmp program add batch start-index 285 ip 239.0.40.225 to-ip 239.0.40.231 hostip 10.146.34.233

  igmp program add batch start-index 292 ip 239.0.4.219 to-ip 239.0.4.248 hostip 10.146.34.233

  igmp program add batch start-index 322 ip 239.0.4.203 to-ip 239.0.4.217 hostip 10.146.34.233

  igmp uplink-port 0/6/0

Now, in order to watch SD channels we must configure the service-port :

service-port 4 vlan 92 vdsl mode ptm 0/0/0 multi-service user-vlan 20 tag-transform translate inbound traffic-table index 7 outbound traffic-table index 7

Then we cannot watch HD channels configured in Multicast VLAN 80.

NoneNone

When we are configuring IPTV service we must take in account the following steps:


1. Create Multicast VLAN

2. Configure uplink-port

3. Configure Igmp Programs

4. Create Igmp User associated to service-port

5. Associate Igmp Membership to service-port



If we compare configuration between SD Multicast VLAN and HD Multicast VLAN, we found that the only one difference is in igmp membership. 


We cannot watch channels for both Multicast-VLAN because of we must associate igmp membership to two Vlans. In the first configuration we have this association only for one VLAN.

In order to associate igmp membership to two VLANs, we must configure the following:

multicast-vlan 80

 igmp multicast-vlan member service-port-list 4

After of this configuration we have only one service-port associated to only one vlan but we can watch channels for two vlans.

Remember that If we do not know ID of service-port we can use the following command :

 (config-mvlan80)#igmp multicast-vlan member smart-vlan 92   ; It's 92 because of VLAN of service-port is 92

service-port 8 vlan 92 vdsl mode ptm 0/0/0 multi-service user-vlan 20 tag-transform translate inbound traffic-table index 7 outbound traffic-table index 7

Conclusion:

1. We must configure two multicast vlan and we must associate igmp membership to two vlans

2. We must create service-port for only one VLAN

3. We must create igmp user for this service-port

Huawei’s 400Gbps core router leads the next-generation optical network

Huawei remains the biggest manufacturer of the world in communication transmission networks, in despite of being locked out of the huge U.S. LTE market relentlessly. Presently, Huawei tested next generation optical networks transmitting method by using WDM technology to 400Gbps links.The requirement for more data communication and larger transmission speed in both fixed and wireless optical networks is still increasing in carriers’ network. Although faster technologies, such as LTE are started, a group of manufacturers are working to improve WDM, as the development speed of wireless network is going forward by leaps and bounds. Through a large number of individual optical fibers, WDM can send large amounts of data.
But, can you image, the experiment that led by Huawei and Exatel used only one channel to transmit communication data. It is a very ideal method in transport network. This means that the system requires only one optical transceiver for transmitting and receiving data. So this can decrease power consumption and reduce chance that things may go wrong in transport. But Huawei didn’t dedicate to use this technology in commercial products.Now, telecom carriers are improving their networks by take advantage of 100Gbps links. That increased third quarter spending on Huaweioptical networks in North America by 13.4% on year-on-year basis, followed an 11.1% in the previous quarter, according to Infonetics Research. Huawei, Ciena, and Alcatel-Lucent were the WDM market share leaders.

Notice: whether SSN4EGS411 and SSND00EGS412 are the same board?

In Huawei optix transmission boards, SSN4 is equal to SSND00, and generally speaking, the same boards that display different product name have the same feature code, like SSN4SL6402 and SSND00SL6402. But When it comes to Huawei service board SSN4EGS411 and SSND00EGS412, some customers are misguided and some customers are asking that whether we delivered the wrong model of board to them, because In huawei BOQ, it is show as SSND00EGS412, here version code is ND00, feature code is 412; But in board front panel, it show as SSN4EGS411, here verison code is N4, but feature code is 411. Actually they are the same board.
To avoid this confuse, we suggest when ordering a EGS4 board, it better to comment with a optical specification behind like: (1000BASE-LX).

For example, when you are about to order a SSN4EGS411 board, you must select maybe you will choose configuration(slots and transmission range etc.) like as follow:

After you selected the configuration of this board, it will appear message box like this:

The product name shows as SSND00EGS412. But the product name that shows on the board is SSN4EGS411.

So when you buy this optical transport model of board later, you won’t be confused again.
