I'm looking for a 4-port Gigabit Fiber Ethernet Switch that features two 1000Base-X SFP slots alongside two 10/100/1000Base-T(X) RJ45 Ethernet ports. This configuration is crucial for our network needs, as we aim to enhance data transfer speeds and reliability within our infrastructure. Could you please provide details on your available options, including pricing, lead times, and any relevant specifications? Additionally, it would be helpful to understand warranty terms and support services that come with the product. Thank you for your assistance!
