Part numbers: 10403, 100G-LR4-QSFP2KM, AA1405001-E6
The LR4 QSPF28 module provides a 100 Gb optical Ethernet connection using LC duplex optical connectors over SMF (single-mode fiber).
This optical module integrates four data lanes on separate WDM (wave division multiplexed) wavelengths in each direction for 100 Gbps aggregate bandwidth. Each lane operates at 25.78 Gbps using single-mode fiber.
For a complete listing of hardware compatible with these modules, 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.
The LR4 QSFP28 module conforms to the 802.3ba 100GBASE-LR4 standard.
