40 Gb LM4 QSFP+ Module

Part number: 10334

The LM4 QSFP+ module (10334) provides a 40 Gb optical connection on a duplex single pair of fibers using single-mode fiber or multimode fiber. It is a cost-effective option for transferring data reliably up to 1 kilometer using single-mode fiber, up to 160 meters using optical multimode fiber (OM4), or up to 140 meters using optical multimode fiber (OM3).

For a complete listing of compatible cables and optical transceivers, see the Extreme Optics Compatibility website.

Transmission distances are provided as a nominal guide only. To determine achievable distances, refer to the device's optical specifications and to the specific characteristics of your fiber installation.
