Part numbers: 10319, 40G-SR4-QSFP150M, 40G-SR4-QSFP150M-NT, AA1404005-E6
The SR4 QSFP+ module provides a 40 Gb optical connection using MTP® (MPO) optical connectors over four pairs of parallel multimode fiber. The SR4 QSFP+ module is compatible with OM3 or OM4 MMF female MTP/MPO 8- or 12-fiber cables.
This optical module integrates four data lanes in each direction with 40 Gbps aggregate bandwidth. Each lane can operate at 10.3125 Gbps up to 100 meters using OM3 fiber or up to 150 meters using OM4 fiber. The SR4 QSFP+ module conforms to the 802.3ba D3.2 (40GBASE-SR4) standard.
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.
The 40 Gb SR4 QSFP+ module conforms to the 802.3ba D3.2 (40GBASE-SR4) standard.
