Cisco compatible MA-QSFP-40G-LR4 Description
EdgeOptic's MA-QSFP-40G-LR4 compatible is a Cisco Meraki-coded version of the EdgeOptic 40G-QSFP-10 multi-vendor 40GBASE-LR4 transceiver. The MA- prefix is Meraki's accessory ordering code, distinct from the standard Cisco IOS QSFP-40G-LR4. It is a QSFP+ module for 40 Gigabit Ethernet over single-mode fiber at distances up to 10 km, coded with Meraki-recognized EEPROM so it is read correctly in the Meraki dashboard.
The module carries 40G Ethernet at 41.25 Gbps across four NRZ lanes on 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 supports a 10 km span over G.652 single-mode fiber terminated with a duplex LC connector. Receiver overload is +3 dBm, and the module operates across a 0 to 70 °C case temperature range.
This optic is built for Cisco Meraki MS cloud-managed switching, an Ethernet-only platform, and is supported on the MS355, MS390, MS425 and MS450. It matches the original MA-QSFP-40G-LR4 optical specifications and conforms to IEEE 802.3ba Clause 87, the QSFP+ MSA and SFF-8436. Confirm port availability against the Meraki switch documentation for the target model before deployment.
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 the MA-QSFP-40G-LR4 report DOM telemetry on Meraki MS switches?
No. Meraki MS switches do not currently expose DOM telemetry for QSFP transceivers; only SFP and SFP+ ports surface DOM data. The Meraki dashboard will not show per-lane temperature, voltage, bias or optical power for this module, so engineers expecting DOM readouts on QSFP+ should plan around the platform limitation rather than the module. Check Meraki's current release notes for any change.
Does Cisco Meraki allow third-party QSFP+ optics on MS355/MS390/MS425/MS450 switches?
Yes. Meraki MS switches do not use a CLI-based optics lockout and need no unsupported-transceiver command. EdgeOptic codes this module with Meraki-recognized EEPROM identifiers so it is accepted in the Meraki dashboard without special configuration. This differs from standard Cisco IOS and NX-OS behavior, where an unsupported-transceiver step can apply. Verify optics compatibility against Meraki's documentation for the target switch.
