Key specifications

How to use

Install the transceiver into an available SFP slot on your switch, router or media converter with the network device powered according to the vendor’s hot-swap guidance. Connect multimode fiber cables using the appropriate duplex connector, ensuring correct alignment and cleanliness of fiber endfaces to minimize signal loss. After physical installation, verify link status via the device’s management interface and confirm negotiated speed at 1000 Mbit/s. For troubleshooting, inspect fiber connectors for contamination and check device logs for link events.

Recommendations

Use high-quality multimode fiber (OM1/OM2/OM3/OM4 as appropriate) and maintain clean connector endfaces. Keep maximum cable lengths within recommended short-range limits for 850 nm links and consult equipment vendor compatibility lists when integrating SFP modules into existing systems.
