SFP-25G-ESR: frequently asked questions
What is the Alcatel-Lucent Enterprise SFP-25G-ESR?
The SFP-25G-ESR is an SFP28 25GBASE-SR extended module for 25 Gbps Ethernet links. It plugs into an SFP28 port on an Alcatel-Lucent Enterprise OmniSwitch and is used for 25G server access and leaf uplinks on OmniSwitch 6900 / 6870.
What is the maximum distance of the SFP-25G-ESR?
The vendor documentation lists the SFP-25G-ESR for ~300m on OM4 MMF.
Which fiber and connector does the SFP-25G-ESR need?
The SFP-25G-ESR uses an LC duplex connector on multimode fiber (OM3/OM4), at 850 nm (nominal). Both ends of the link must use the same optical standard.
Which OmniSwitch models support the SFP-25G-ESR?
ALE lists its transceivers per switch family in each OmniSwitch datasheet and the AOS Transceivers Guide; the SFP-25G-ESR is listed in current (2024–2026) OmniSwitch datasheets. Send us your OmniSwitch model and AOS release and we check it before dispatch, so the port accepts the optic without a 'non-ALE transceiver' warning.
Can I use a third-party SFP instead of the ALE SFP-25G-ESR?
OmniSwitch ports log a warning for non-ALE coded optics and ALE support may ask you to use ALE parts. Next Gen Networks supplies the genuine ALE SFP-25G-ESR; if you want a lower-cost ALE-coded compatible module for non-critical links, ask us and we will quote both options.
Is your SFP-25G-ESR genuine ALE?
Yes. Next Gen Networks supplies original Alcatel-Lucent Enterprise parts, not third-party lookalikes or grey-market stock. Every unit is checked before dispatch and we share serial numbers on request so you can verify them in the switch or router transceiver inventory.
What is the SFP-25G-ESR price in India and how do I order?
The Alcatel-Lucent Enterprise SFP-25G-ESR price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
