Extreme compatible 40G-LR4-QSFP10KM Description
EdgeOptic's 40G-LR4-QSFP10KM compatible is an Extreme Networks-coded version of the EdgeOptic 40G-QSFP-10 multi-vendor 40GBASE-LR4 transceiver. It is a QSFP+ module built for 40 Gigabit Ethernet over single-mode fiber at distances up to 10 km, programmed with Extreme-recognized EEPROM so it identifies cleanly on Extreme Networks QSFP+ switches running ExtremeXOS.
The module carries 40G Ethernet at 41.25 Gbps using four NRZ lanes multiplexed onto a CWDM4 grid at 1271, 1291, 1311 and 1331 nm. It uses DFB lasers and a PIN photodiode, with per-lane launch power from −6 to +3 dBm and receiver sensitivity of −12.6 dBm per lane. The 6.6 dB link budget covers a 10 km span on standard G.652 single-mode fiber terminated with a duplex LC connector. The receiver tolerates input up to +3 dBm before overload, and the module operates across a 0 to 70 °C case temperature range. Digital optical monitoring is available for real-time tracking of temperature, supply voltage, bias current and optical power.
This is an Ethernet-only optic for Extreme Networks EXOS switching applications. It matches the original 40G-LR4-QSFP10KM optical specifications and conforms to IEEE 802.3ba Clause 87, the QSFP+ MSA, INF-8438i and SFF-8436. Before deployment, confirm the exact module against Extreme's optics compatibility database for the target switch.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For deployment questions or bulk pricing, contact our sales team.
Frequently Asked Questions
Does ExtremeXOS require a third-party optics license for the 40G-LR4-QSFP10KM on 40G ports?
Older ExtremeXOS builds required a 3rd Party Optics feature license to run non-Extreme optics on 40G and 100G ports, and without it egress throughput on those ports was throttled. Extreme has removed that requirement in current ExtremeXOS versions, so the license is no longer needed on up-to-date switches. Check the running ExtremeXOS version against Extreme Networks documentation before deployment if the switch is on an older firmware train.
