Key specifications

How to use

Install the transceiver into a compatible QSFP port on a switch, router or network interface card following the host equipment guidelines. Ensure the transceiver and host port are powered off or follow the vendor’s hot-plug instructions if supported. Connect appropriate multimode fiber cables with matched MPO/MTP connectors and verify link status through the host device management interface. Monitor signal and link indicators to confirm correct operation and troubleshoot using host diagnostics if required.

Recommendations

Use quality multimode fiber and clean connectors to maintain signal integrity; adhere to the supported short-reach distance specifications for SR4 optics. Confirm compatibility with the host device’s QSFP port and firmware, and replace or reseat the module only when the link is down or according to the equipment maker’s hot-swap guidelines.
