美国采购需求：GPON OLT、GPON ONU、XGS-PON、ONT、EDFA、光发射机

I'm reaching out to inquire about a couple of product references I came across. I'm particularly interested in obtaining pricing details and availability for a bulk order of around 20 tons. Please provide me with your best offer, including any minimum order quantities and lead times you can accommodate. Additionally, if there are any specifications or certifications related to these products that I should be aware of, please include that information as well. It would be great if you could send over any datasheets or relevant documentation to help me evaluate the options. Looking forward to your prompt response so we can move forward!
