Cisco compatible MA-QSFP-100G-LR4 Description
EdgeOptic's MA-QSFP-100G-LR4 compatible is a Cisco Meraki-coded 100GBASE-LR4 QSFP28 transceiver, built on the same 100G-QSFP28-10 hardware platform we use across the LR4 family. The MA- prefix is the Cisco Meraki accessory designation, separate from the enterprise Cisco QSFP-100G-LR4-S SKU; the two part numbers cover different EEPROM coding and different Cisco ecosystems. Our compatible carries Meraki-recognized vendor identification so the module presents as a genuine Meraki accessory in the Meraki Dashboard inventory.
Optically the module conforms to IEEE 802.3ba Clause 88. Four LAN WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm are multiplexed onto a single duplex single-mode fiber pair. Each lane carries 25.78125 Gbps NRZ for an aggregate line rate of 103.125 Gbps, which delivers 100 Gbps of net payload after 64B/66B encoding. The optical path loss budget is 6.3 dB, sufficient for 10 km of G.652 single-mode fiber with standard connector and splice losses. The host interface is CAUI-4 (4x25G NRZ); host-side RS-FEC is supported transparently when enabled by the platform.
QSFP28 MSA SFF-8665 and SFF-8636 management compliance covers the electrical and software interfaces. DDM/DOM telemetry exposes per-lane TX and RX optical power, module temperature, supply voltage and laser bias current; on Meraki, these readings surface through the Dashboard's port and module diagnostics. The duplex LC connector accepts standard SMF patch cords, and the commercial 0 to 70 °C operating temperature range covers typical wiring-closet and aggregation-room environments.
Meraki documents the MA-QSFP-100G-LR4 for the MS450 aggregation switch 100G QSFP28 uplink ports in its SFP and stacking accessories overview. Meraki switches are cloud-managed via the Meraki Dashboard, so there is no traditional IOS-XE or NX-OS CLI; configuration and inventory all happen through the Dashboard interface. Meraki's stated policy is permissive on third-party accessories: the platform does not lock out non-Meraki optics, but Meraki only certifies and warranties its own MA-prefix branded modules. For the most current platform list (including non-MS450 switches that may carry 100G QSFP28 uplinks), verify against the Meraki SFP and stacking accessories documentation for the chassis you are commissioning.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project-quantity pricing or alternative vendor coding, contact our sales team.
Frequently Asked Questions
Is the MA-QSFP-100G-LR4 the same as the Cisco QSFP-100G-LR4-S?
Optically yes, electrically and operationally no. Both are 100GBASE-LR4 QSFP28 modules conforming to IEEE 802.3ba Clause 88, so an MA-QSFP-100G-LR4 at one end of an SMF link and a QSFP-100G-LR4-S at the other will pass traffic. The two part numbers cover different Cisco ecosystems: MA-QSFP-100G-LR4 is the Meraki accessory SKU for cloud-managed Meraki switching, while QSFP-100G-LR4-S is the enterprise Cisco SKU for IOS-XE and NX-OS platforms (Catalyst, Nexus, NCS). EEPROM coding is different on each, so order the part number that matches your Cisco ecosystem.
Which Meraki switch models support the MA-QSFP-100G-LR4?
Meraki documents the MA-QSFP-100G-LR4 for the MS450 aggregation switch in its SFP and stacking accessories overview. The MS450 is the Meraki switch family that exposes 100G QSFP28 uplinks alongside its 40G ports. For other Meraki MS-series chassis that may carry 100G QSFP28 ports across firmware revisions, verify against the current Meraki SFP and stacking accessories compatibility table for the model you are commissioning.
Does the Meraki Dashboard flag third-party compatible optics?
Meraki's published policy is that the platform does not lock out non-Meraki optics; however Meraki only certifies and warranties its own MA-prefix branded modules. EdgeOptic's MA-QSFP-100G-LR4 compatible carries Meraki-recognized vendor identification so it presents as a Meraki accessory in the Dashboard inventory. Meraki support may ask customers to switch back to certified optics during troubleshooting; if that constraint matters for the deployment, factor it into the procurement decision.
How are DDM values monitored on Meraki switches?
Meraki exposes Digital Optical Monitoring readings through the Meraki Dashboard's port and module diagnostics views, with per-lane TX and RX optical power, module temperature, supply voltage and laser bias current visible on the switch detail page. Because Meraki is cloud-managed, there is no equivalent of an IOS-XE 'show interfaces transceiver' CLI; all telemetry surfaces through the Dashboard interface.
