哥伦比亚采购需求：OLT 和 PON 模块

I'm reaching out to inquire about the SFP mini OLT module, as I'm quite interested in its features and functionality. As I'm not fully familiar with how it operates, I would appreciate a detailed explanation or any relevant documentation you could provide. Additionally, I would like to know the pricing details for these modules. Since I'm located in Colombia, please include any shipping information or costs associated with international orders. Thank you!
