Cisco compatible QSFP-100G-ZR4-S Description
The EDGE 100G-QSFP28-80 is a direct replacement for the Cisco QSFP-100G-ZR4-S, coded with Cisco-recognized EEPROM so NX-OS and IOS-XE identify it as a supported optic without any workaround commands. It ships with the same LC duplex connector and the same 80km single-mode reach.
The module operates over 100GBASE-ZR4, using four LAN-WDM wavelengths (1295.56, 1300.05, 1304.58, 1309.14nm) across a duplex LC single-mode fiber pair. Line rate is 103.125 Gbps (4 lanes at 25.78125 Gbps each, 64B/66B encoded). The module is rated for a 30dB maximum optical link budget with FEC, supporting links up to 80km over OS2 single-mode fiber. Case temperature range for the -S variant is 0 to 70°C (commercial/standard).
QSFP-100G-ZR4-S is used on Cisco Nexus 9000 (93xx, 95xx, 96xx), Catalyst 9500 and 9500H, ASR 9000 with 100G line cards, and NCS 5500/5000 series. Nexus 7000 with F3 line cards and Nexus 3000 also have QSFP28 ports. No optics-specific license or CLI override is required for this module on any of these platforms. Check the Cisco HCL for your specific line card and NX-OS or IOS-XE release.
Cisco uses two related SKUs for this module: QSFP-100G-ZR4-S (standard temperature, 0-70°C, the most common variant for data center and campus deployments) and Q100-ZR4-S-EA (an alternate SKU used in certain Cisco purchasing programs, same optical specs). If your purchase order references QSFP-100G-ZR4-S without the EA suffix, this is the correct EDGE replacement. For the EA variant, see the Q100-ZR4-S-EA compatible product page.
The module is compliant with the 100GBASE-ZR4 MSA and the QSFP28 Multi-Source Agreement for mechanical and electrical interoperability. DDM/DOM per SFF-8636 provides real-time readings for transmit power, receive power, temperature, voltage, and bias current through your NMS or CLI.

Frequently Asked Questions
Which Cisco platforms support the QSFP-100G-ZR4-S?
QSFP-100G-ZR4-S is used in the Nexus 9000 series (93xx, 95xx, 96xx), Catalyst 9500 and 9500H, ASR 9000 with 100G line cards, and NCS 5500/5000 series. Nexus 7000 with F3 line cards and Nexus 3000 also have QSFP28 ports, though ZR4-S qualification on those platforms depends on NX-OS version. Check the Cisco Hardware Compatibility List for your specific line card and software release.
What does the "-S" suffix mean on QSFP-100G-ZR4-S?
The "-S" means standard (commercial) temperature range: 0 to 70°C case temperature. This is the variant used in data center and enterprise deployments with controlled ambient temperatures. Cisco also offers an extended-temperature variant for outdoor or uncontrolled environments. The two are different part numbers and not interchangeable for warranty or TAC purposes.
Do I need the "service unsupported-transceiver" command for this module on Cisco NX-OS or IOS-XE?
No. The EDGE QSFP-100G-ZR4-S compatible is programmed with Cisco-recognized EEPROM data, so NX-OS and IOS-XE identify it as a supported optic. You will not see the "unsupported transceiver" syslog message, and the interface comes up without any additional configuration.
What is the difference between QSFP-100G-ZR4-S and Q100-ZR4-S-EA?
The optical specifications are identical: same wavelengths, same reach, same QSFP28 form factor. The difference is the purchasing channel. QSFP-100G-ZR4-S is the standard Cisco SKU available through normal reseller channels. Q100-ZR4-S-EA is an alternate SKU used in certain Cisco purchasing programs. Both map to the same 100GBASE-ZR4 optic with different part numbers in the Cisco ordering system.
