Cisco compatible MA-QSFP-100G-LR4 Description
MA-QSFP-100G-LR4 is the Cisco Meraki part number for a 100GBASE-LR4 QSFP28 transceiver. This EDGE compatible module matches the original specifications and is built to the same MSA standards, with EEPROM coded for Meraki platform recognition. It operates over duplex single-mode fiber at four LAN-WDM wavelengths (1295.56, 1300.05, 1304.58, and 1309.14 nm), reaching up to 10 km with a minimum optical link budget of 6.3 dB per IEEE 802.3ba.
The module uses EML transmitters and PIN photodiode receivers, carrying four lanes at 25.78125 Gbps each for an aggregate 103.125 Gbps line rate. DDM/DOM provides real-time readings of TX/RX optical power, laser bias current, temperature, and supply voltage. Maximum power consumption is 3.5 W from a single 3.3 V supply. Operating temperature range is 0 to 70 °C. The duplex LC connector works with standard OS2 single-mode patch cords.
Meraki cloud-managed switches do not enforce transceiver authentication, so no CLI commands are needed to enable third-party optics. The MA-QSFP-100G-LR4 works in the Meraki MS450-12 QSFP28 uplink ports and in Catalyst 9300X-M switches managed through the Meraki dashboard. The MS450 QSFP28 ports operate at 100G only; 40G downshift with QSFP+ modules is not supported.
The MA-QSFP-100G-LR4 and Cisco QSFP-100G-LR4-S are optically identical: same wavelengths, same link budget, same QSFP28 form factor. The difference is EEPROM vendor coding and the support channel (Meraki license vs. Cisco SMARTnet). Our compatible module can be programmed for either platform on request.
Our compatible MA-QSFP-100G-LR4 is CE and RoHS certified, QSFP28 MSA-compliant, and conforms to IEEE 802.3ba. Before delivery, every module undergoes optical parameter measurement, connector cleanliness inspection, and EEPROM data validation testing.

Frequently Asked Questions
Do I need to run 'service unsupported-transceiver' on Meraki like on Cisco IOS?
No. Meraki cloud-managed switches do not enforce transceiver authentication. Compatible optics work without any CLI commands. This is different from Cisco IOS and IOS-XE platforms, which require the service unsupported-transceiver command to accept third-party modules.
Which Meraki switches support the MA-QSFP-100G-LR4?
The Meraki MS450-12 has two QSFP28 uplink ports and two QSFP28 stacking ports that accept the MA-QSFP-100G-LR4. The Catalyst 9300X-M series with the C9300X-NM-2C-M network module also supports QSFP28 100G optics when managed through the Meraki dashboard. Check your specific Meraki switch model's datasheet to confirm QSFP28 port availability, as uplink configurations vary across the MS product line.
What is the difference between MA-QSFP-100G-LR4 and Cisco QSFP-100G-LR4-S?
Both are 100GBASE-LR4 QSFP28 modules with identical optical specifications. The MA- prefix denotes Meraki-branded EEPROM coding, while QSFP-100G-LR4-S uses standard Cisco coding. Cisco-branded optics technically work in Meraki switches, but warranty and RMA may require cross-launching a TAC case. Our compatible module can be coded for either platform.
Does the Meraki dashboard show DOM data for 100G QSFP28 optics?
DOM monitoring in the Meraki dashboard is supported for SFP/SFP+ modules on firmware MS 17 and later, but is not currently available for QSFP28 transceivers. The module itself supports DDM and reports optical power, temperature, and bias current through the standard I2C interface, but the dashboard does not display this data for QSFP ports.
