马来西亚采购需求：光纤收发器、以太网交换机、POE交换机、工业交换机、光模块、4G路由器

I'm looking for an 18-port industrial Ethernet switch that supports 10/100M and 1000M speeds. It's crucial that the switch is robust enough for industrial environments, with features like redundant power inputs, DIN rail mounting options, and possibly even support for PoE. Please provide details about your product specifications, including the data throughput, environmental ratings, and any additional features that would suit high-demand scenarios. In addition, I would appreciate information on your lead times, warranty coverage, and any certification standards the product meets. If available, please send over pricing information and bulk order discounts, as I am considering a larger purchase for our upcoming projects. Looking forward to your prompt response with the detailed specifications and options.
