Connect Gates Recommendation:
• Connect Gates recommends the D-Link DGS-3700-12G for telecom, service provider, and enterprise fiber access projects that require a compact Gigabit Metro Ethernet switch with strong SFP connectivity.
• It is an ideal choice when the project depends mainly on fiber links, while still needing flexible combo copper/SFP ports for uplinks, local connection, or service handoff.
• The DGS-3700-12G is especially suitable for ETTH, ETTB, telecom cabinets, ISP access networks, campus fiber distribution, and CCTV fiber backbone projects.
• For best performance, Connect Gates recommends selecting the suitable SFP or WDM SFP transceivers according to fiber type, distance, wavelength plan, and network topology, with proper planning for AC/DC power and cabinet ventilation.
