• High-density multimode fiber installations using MPO/MTP trunks
• Short-range interconnects for enterprise LAN backbones

Key specifications

• Data rate: 40 Gb/s over multimode fiber
• Optical interface: MPO/MTP parallel connector
• Supported link type: short-range multimode transmission (SR4)
• Form factor: compact hot-pluggable module
• Typical reach: designed for short-reach multimode links (data center distances)
• Compatibility: intended for use with 40G Ethernet equipment and multimode fiber cabling

How to use

Install the transceiver into a compatible 40G-capable port on a switch or router while the device is powered on, taking care to align the MPO/MTP connector correctly with the fiber trunk. Verify link status through the host device management interface and, if necessary, configure port settings for 40G operation. For maintenance, use the hot-pluggable capability to replace or upgrade the module without powering down the system; ensure static-safe handling and dust protection for optical interfaces during insertion and removal.

Recommendations

For optimal performance, use multimode fiber with the appropriate OM grade specified by your network design, keep MPO/MTP connectors clean and protected with dust caps when not in use, and follow vendor guidance on cable polarity and trunk mapping. Verify transceiver compatibility with your switch model and firmware to ensure proper link negotiation and optical performance.
