爱尔兰采购需求：GPON OLT、GPON ONU、XGS-PON、ONT、EDFA、光发射机

I'm inquiring about pricing for a networking system tailored for a small business environment. We're looking for a solution that can support our daily operations, including file sharing, internet access, and secure communication among employees. Ideally, the system should be scalable to accommodate future growth as our business expands. Additionally, I'd like to know about the different components included, such as routers, switches, and any necessary accessories. A brief overview of your installation services and ongoing support options would also be appreciated. Please provide any available product options that fit our needs, as well as lead times for delivery and installation. Thanks!
