Compatibility & Software Support
Compatible Switches
D-Link designs the DIS-S300 series for its Industrial Ethernet switches with SFP slots, such as the DIS-300G-12SW and DIS-700G-28XS. Ask us to confirm support on your specific switch.
Link Planning
Use a matching 1000BASE-LHX module at each end of the single-mode link. On short links a long-reach optic may need attenuation — ask us before using it below its intended range.
