QSFP-100G-LR4: frequently asked questions
What is the Alcatel-Lucent Enterprise QSFP-100G-LR4?
The QSFP-100G-LR4 is a QSFP28 100GBASE-LR4 module for 100 Gbps Ethernet links. It plugs into a QSFP28 port on an Alcatel-Lucent Enterprise OmniSwitch and is used for 100G core and data-center links on OmniSwitch 6900 (C32 / V72 / X48C6 / T48C6) and 9900.
What is the maximum distance of the QSFP-100G-LR4?
The vendor documentation lists the QSFP-100G-LR4 for 10km SMF.
Which fiber and connector does the QSFP-100G-LR4 need?
The QSFP-100G-LR4 uses an LC duplex connector on single-mode fiber (OS2), at 4 x LAN-WDM lanes 1294.53-1296.59 / 1299.02-1301.09 / 1303.54-1305.63 / 1308.09-1310.19 nm. Both ends of the link must use the same optical standard.
Which OmniSwitch models support the QSFP-100G-LR4?
ALE lists its transceivers per switch family in each OmniSwitch datasheet and the AOS Transceivers Guide; the QSFP-100G-LR4 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 QSFP-100G-LR4?
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 QSFP-100G-LR4; if you want a lower-cost ALE-coded compatible module for non-critical links, ask us and we will quote both options.
Is your QSFP-100G-LR4 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 QSFP-100G-LR4 price in India and how do I order?
The Alcatel-Lucent Enterprise QSFP-100G-LR4 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.
