Extreme compatible 100G-CWDM4-QSFP2KM Description
EdgeOptic's 100G-CWDM4-QSFP2KM compatible is an Extreme Networks-coded CWDM4 QSFP28 version of the EdgeOptic 100G-QSFP28-2.1 multi-vendor 100G CWDM4 2km transceiver. Extreme Networks documents the OEM optic as the 100 Gb CWDM4 2 km SMF QSFP28 Module in its pluggable transceiver portfolio, distinct from the 100G LR4 LAN-WDM 10km variant in the same family.
The module runs four CWDM channels on the 1271, 1291, 1311, and 1331 nm wavelength plan defined by the CWDM4 MSA and ITU-T G.694.2, with NRZ modulation at 25.78 Gbps per lane. Output uses a duplex LC connector and supports links from 2 m to 2 km over G.652 single-mode fibre. The optical front end uses DML transmitters and PIN receivers, with host-side FEC supported per the CWDM4 MSA Technical Specification.
The 100G-CWDM4-QSFP2KM covers 100 Gigabit Ethernet on Extreme Networks switching and routing platforms at 103.125 Gbps per Extreme's documentation. The EdgeOptic 100G-QSFP28-2.1 family additionally supports OTU4 (112 Gbps) and 4x32G Fibre Channel (112.2 Gbps) variants for OTN transport and SAN deployments. Those rates ship as separate part numbers, so for OTU4 or Fibre Channel coding contact our sales team.
100G-CWDM4-QSFP2KM is the Extreme Networks ordering code for the 2km CWDM4 option, qualified across the SLX router family and Summit X series chassis that accept QSFP28 transceivers. Verify the supported slot and line card position against the Extreme Networks pluggable transceiver documentation for the platform image and chassis revision in service.
EdgeOptic codes the 100G-CWDM4-QSFP2KM compatible with Extreme Networks-recognized EEPROM, so ExtremeXOS, EXOS, and SLX-OS interface validation accepts the module under standard transceiver registration. The EEPROM identifies the optic against the 100G-CWDM4-QSFP2KM part number so management interfaces and chassis inventory tooling report it consistently with Extreme-branded OEM stock.
Digital diagnostics (DDM/DOM) report TX power, RX power, bias current, supply voltage, and temperature per SFF-8636. The module is QSFP28 MSA SFF-8665 compliant and aligned with the CWDM4 MSA Technical Specification.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.
Frequently Asked Questions
How is the 100G-CWDM4-QSFP2KM different from Extreme Networks' 100G LR4 QSFP28 variant?
The 100G-CWDM4-QSFP2KM is a CWDM4 module on the 1271, 1291, 1311, and 1331 nm wavelength plan with 2 km reach over single-mode fibre. Extreme's 100G LR4 variant uses the LAN-WDM 1295 to 1309 nm wavelength grid for 10 km reach. Extreme Networks documentation explicitly states the two are not interoperable end-to-end on the same span because the wavelength plans do not overlap. Match transmit and receive optics by wavelength plan and reach class when commissioning either side of the link.
