This is not a valid response.
No, I do not work at Huawei and no, I do not know if the company have any backup components or suppliers. But your response revealed an ignorance of manufacturing in general.
Suppliers are always eager to do business with you, but if you tell me that I would be relegated to 'backup' status, I would tell you to 'have a nice day' and I would move on to the next prospect. You can contact me later and we can collaborate and hopefully we can do business, but I am not going to keep an open line to support your unique products. I cannot afford to make components just to keep them on the shelves just in case you call. I can resurrect my manufacturing lines but the restart cost would be included in any charges to you.
When I used to work for Micron Tech, the company was and still is notorious for keeping obsoleted product designs available for anyone, provided they are willing to pay the cost. NASA decided a certain design of obsoleted DRAM was the best candidate to survive the rigors of space and after finding no one was willing to support its mission, NASA contacted Mu and paid the necessary cost.
So yes, we can assume that Huawei do have reserve components, but for how many days? Not yrs, but days. Storing
YRS worth of parts for any 'just in case' scenario is itself a cost, especially if you have multiple sites and multiple product lines. The main -- if not the only -- reason you keep days worth of components is to compensate for any on-site events such as a storm that cut your power and damaged a product line under critical manufacturing processes. Human caused events like a technician accidentally bumped into an 'emergency power off' (EPO) button on a critical machine. A new product line start up of a new design. And more situations.
But a reserve of components is not the same as having suppliers waiting hands-and-feet to you. I do not care how large and/or important you are, not even if you are Apple or Microsoft or Boeing or NASA. Holding unique components for you does not guarantee profits for me. It just cost me storage space but nothing to you.
Having multiple suppliers of the same product is a viable option and many companies actually do take that route. But the law of supply and demand matters. The less I produce for you, the higher the cost per unit to you. The other supplier(s) will do the same to you. And in the end, you will end up paying an overall higher cost per unit for the convenience of having multiple suppliers. The laws of business are as solid as the laws of nature.
So let us take a look at Huawei's list of suppliers again, shall we...Specifically the ones that supplies connectors...
Amphenol is the only US supplier of connectors. But what kind of connectors and for what applications inside Huawei's products? The same question applies to the other connectors suppliers. What if Amphenol -- like Micron Tech -- is the only supplier of connectors that Huawei need? What if the same issue applies to the other connectors suppliers? Each of them sells unique connectors to Huawei that the others do not.
Critical thinking is clearly not in your toolbox, compounded worse by your non experience in manufacturing.
How long is that 'awhile' are you going to endure?
None. I have not urinate nor defecate in decades. My body is so efficient that it process everything I ingest to the fullest. The only thing my body excretes is sweat for cooling.
