SFP+, XFP, QSFP+, DAC Twinax Cable 10Gtek Transceivers Co., Ltd
AOC (Active Optical Cable) 10Gtek''s SFP+ Active Optical Cables are hot-swappable, low-voltage cable assemblies that connect directly into SFP+ modules at both ends.
Connect the fiber optic cables to switches at both ends
To connect a fiber optic cable between two switches, use compatible SFP transceivers, duplex fiber cabling, and ensure proper port configuration and cable polarity.Equipment NeededSFP or SFP+ transceivers compatible with your switch and fiber type (single-mode or multimode) .Duplex fiber optic cable (two strands) with LC connectors, either pre-terminated or terminated in the field .Optional: Direct Attach Cables (DACs) for short distances with pre-terminated SFP modules .Steps to ConnectInstall SFP Modules: Insert the SFP transceivers into the fiber ports of both switches. Ensure the SFP type matches the fiber (e.g., multimode SFP with multimode fiber) .Use Duplex Fiber Cabling: Connect the two strands of the fiber cable to the SFP modules. One strand is for transmitting (TX) and the other for receiving (RX). Make sure the connections are reversed between switches (TX on switch A to RX on switch B and vice versa) .Check Port Configuration: On Cisco switches, enable the interface if necessary using no shutdown. Verify VLAN assignments if you want the fiber link to carry traffic for specific VLANs .Verify Link: Check the link lights on the SFP ports. If the lights do not turn on, confirm the fiber type, SFP compatibility, and cable polarity .Test Connectivity: Ping devices across the switches to ensure the fiber link is operational.Tips and ConsiderationsFiber Type Matching: Single-mode SFPs must use single-mode fiber; multimode SFPs must use multimode fiber .Pre-terminated Cables: Using pre-terminated fiber cables saves time and reduces installation errors .SFP Compatibility: Some third-party SFPs may not work with certain switch brands; always verify compatibility .Distance and Bandwidth: Ensure the SFP module supports the required distance and network speed (1G, 10G, etc.) .Cascading Switches: When connecting multiple switches, consider network topology (star, daisy chain) and limit cascades to maintain performance . By following these steps and ensuring proper SFP and fiber selection, you can establish a reliable fiber optic connection between two switches.
