Cisco compatible Q100-ZR4-S-EA Description
The EDGE 100G-QSFP28-80 is a direct replacement for the Cisco Q100-ZR4-S-EA. This SKU refers to the same 100GBASE-ZR4 QSFP28 optic as the QSFP-100G-ZR4-S — identical optical specs, identical platform compatibility, just a different Cisco ordering part number. The EDGE module is coded with Cisco-recognized EEPROM, so NX-OS and IOS-XE accept it without CLI workarounds.
The module uses 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). Rated for a 30dB maximum optical link budget with FEC, supporting links up to 80km over OS2 single-mode fiber. Power consumption is 6W (Cisco power class 8). Operating temperature 0 to 70°C.
Q100-ZR4-S-EA is qualified on the same Cisco platforms as QSFP-100G-ZR4-S: Nexus 9000 (93xx, 95xx, 96xx), Catalyst 9500 and 9500H, ASR 9000 with 100G line cards, and NCS 5500/5000 series. No optics-specific license or CLI override is required for this module.
Cisco maintains separate datasheets for Q100-ZR4-S-EA and QSFP-100G-ZR4-S, but the underlying module is the same 100GBASE-ZR4 QSFP28. If your procurement system, spares inventory, or Cisco contract references Q100-ZR4-S-EA, this is the correct EDGE replacement.
The module conforms to the 100GBASE-ZR4 MSA and the QSFP28 Multi-Source Agreement. 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
What does EA mean in Q100-ZR4-S-EA?
The Q100 prefix and EA suffix are part of Cisco's alternate ordering system. Q100-ZR4-S-EA and QSFP-100G-ZR4-S refer to the same 100GBASE-ZR4 QSFP28 optic with identical optical specifications, 80km reach, and platform compatibility. The difference is purely administrative — your purchase order or Cisco contract determines which SKU appears. The EDGE replacement is the same for both.
Is Q100-ZR4-S-EA the same module as QSFP-100G-ZR4-S?
Yes. The optical specifications, platform compatibility, and physical module are identical. Cisco uses two part numbers for different purchasing channels. If your spares inventory or PO references Q100-ZR4-S-EA, this is the correct EDGE replacement. The EEPROM coding is Cisco-recognized, so NX-OS and IOS-XE accept it without CLI workarounds.
Which Cisco platforms support Q100-ZR4-S-EA?
The same platforms as QSFP-100G-ZR4-S: Nexus 9000 (93xx, 95xx, 96xx), Catalyst 9500 and 9500H, ASR 9000 with 100G line cards, and NCS 5500/5000 series. No optics-specific license or CLI override is required. Check the Cisco Hardware Compatibility List for your specific line card and NX-OS or IOS-XE release.
