Suitable for

  • High-speed uplinks between switches and aggregation points
  • Data center backbone connections and server interconnects
  • Enterprise networks requiring high-bandwidth links
  • Optical switch ports and QSFP-capable line cards

Key specifications

  • Interface type: QSFP
  • Maximum data transfer rate: 40000 Mbit/s
  • Housing material and colour: stainless steel
  • Form factor: QSFP-compatible transceiver module

How to use

Install the transceiver into a compatible QSFP port on your network device following the device manufacturer's hot-plug or insertion instructions. Ensure both ends of the fiber connection use appropriate optical cables and connectors matched to the transceiver's optical requirements. After insertion, verify link status and configure network settings on connected equipment as required. Follow standard handling practices for optical modules to avoid contamination and mechanical damage.

Usage recommendations

Operate the transceiver within the equipment's specified temperature and power ranges and use certified optical cables and connector cleaning procedures to maintain link quality. For high-density installations, plan port assignments and airflow to ensure proper cooling of QSFP modules. If link issues occur, check fiber polarity, connector cleanliness, and device compatibility with QSFP transceivers.
