How to use

Ensure the host device supports 1000BASE-SX SFP modules and power down or place the port in a safe state if required by the equipment vendor. Insert the SFPSXMM module into an available SFP slot until it seats firmly and secure any retaining mechanism. Connect multi-mode LC fiber patch cables to the module, observing correct TX/RX orientation. After insertion, verify link status on the switch or router and configure the interface as needed for your network settings. The module is hot-swappable on supported equipment, allowing insertion or removal without powering down the host.

Usage recommendations

Use OM1/OM2/OM3 multi-mode fiber appropriate for the distance and application; for best results within the stated 550 m range, follow your fiber cabling standards and maintain clean LC connector endfaces. Keep firmware and device compatibility in mind and consult StarTech.com support if an interoperability issue arises.
