Part number: 10502
The SR-Lite MMF SFP28 module provides a 25 Gb optical connection using a duplex LC optical connector over one pair of multimode fiber. The SR-Lite SFP28 module can support operation with FEC disabled or lite-FEC (Clause 74 Base-R/Firecode) for lower latency applications.
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 with FEC configured on the host switch (or up to 30 meters using OM3 fiber and 40 meters using OM4 fiber without FEC configured).
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 SR-Lite MMF SFP28 module conforms to the 802.3 25GBASE-SR standard.
This module is a Class 1 laser device.
