Part numbers: 40GB-ESR4-QSFP, AA1404006-E6
The ESR4 extended range QSFP+ module provides a 40 Gb optical connection using MTP® (MPO) optical connectors over four pairs of parallel multimode fiber.The ESR4 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 operates at 10.3125 Gbps up to 300 meters using OM3 fiber or up to 400 meters using OM4 fiber. The ESR4 extended range 40Gb QSFP+ transceiver is interoperable with standard 40GBASE-SR4 interfaces within the supported range of the 40Gb SR4 interface. The ESR4 extended range QSFP+ transceiver is also compatible with any 10GBASE-SR interface, when used in 10Gb Ethernet breakout mode, up to 300 meters using OM3 fiber or up to 400 meters using OM4 fiber.
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.
