Part numbers: 10501, 25G-SR-SFP100M
The SR SFP28 module provides a 25 Gb optical connection using an LC duplex optical connector over one pair of OM3 or OM4 multimode fibers. The SR SFP28 module is compatible with OM3 or OM4 MMF duplex cables.
One data lane operates in each direction, at 25 Gbps up to 70 meters using OM3 fiber or up to 100 meters using OM4 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 25 Gb SR SFP28 module conforms to the 802.3 25GBASE-SR standard.
This module is a Class 1 laser device.
