All productsThere are various kinds of optical modules in the market, and some dishonest sellers make fake HUAWEI label to cover up the authenticity of the optical modules, they will find out thousands of excuses to refuse return back, when you found it is not compatible with your switch weeks later.
The purpose is to ensure that the optical modules we deliver do not have compatibility problems. We will test each batch of optical modules to avoid compatibility problems of switch to the greatest extent.
As the general transmission equipment and OLT equipment have good tolerance for optical modules, they can be used normally as long as the optical specification can correspond to them. Therefore, we only test the optical modules compatibility of switch.
There are many customers who are not very clear about what kind of optical module they need. They often simply describe original, DDM, compatible and so on. However, customer’s description doesn’t really make the question clear. For example, the original optical module used for Huawei transmission does not necessarily have no alarm when it is used on Huawei switch. Not all individually packaged optical modules belong to original. Whether non certain PN optical modules can be used on switches or not … In order to eliminate these interferences before purchase, we will carry out the tests mentioned above.
1. We chose Huawei S5700-28C-EI-24S and S6720S-26Q-LI-24S-AC switches for testing.
2. Use console line to connect computer and the CON port of switch
3. Use CRT to log in to the switch
4. Use “display transceiver verbose” command, and the following information will be obtained. 01 port and 02 port, two optical modules are extracted as examples:

5. Insert the optical module, there will be no alarm immediately. After waiting for a few minutes, if the switch pops up an alarm, it will be displayed as follows:
HUAWEI SRM/3/SFP_EXCEPTION:OID 1.3.6.1.4.1.2011.5.25.129.2.1.9 Optical module exception, SFP is not certified. (EntityPhysicalIndex=67469390, BaseTrapSeverity=5, BaseTrapProbableCause=136192, BaseTrapEventType=9, EntPhysicalContainedIn=67108873, EntPhysicalName=XGigabitEthernet0/0/1, RelativeResource=Interface XGigabitEthernet0/0/1 optical module exception, ReasonDescription=It has been observed that a transceiver has been installed that is not certified by Huawei Ethernet Switch. Huawei cannot ensure that it is completely adaptive and will not cause any adverse effects. If it is continued to be used, Huawei is not obligated to provide support to remedy defects or faults arising out of or resulting from installing and using of the non-certified transceiver.)
At present, there is no clear evidence to show that there must be no alarm or alarm for any PN, vendor or module with any appearance. We have also tested many well-packed individually packaged optical modules. The label is printed with HUAWEI, but vendor name shows that it is not Huawei, and has alarm. There are also many vendor names that are not Huawei, but there is no alarm.
Therefore, care must be taken before purchasing optical modules. Do not only look at the appearance or listen to seller’s words, but insert them into the switch for testing, no not pursuit price as only factor, but should consider the essence matters.
Thunder-link.com will test each batch of optical modules and truthfully inform customers the test results, before you decide to purchase, to ensure your benefits.
