Cisco Q100-ZR4-S-EA 100GBASE-ZR4 QSFP28 Extended Long-Reach Single-Mode Transceiver Module (80km) The Cisco Q100-ZR4-S-EA is a premium, high-capacity 100G optical transceiver specifically engineered for extended long-reach backbones and metropolitan Data Center Interconnects (DCI). Utilizing a high-precision 4-lane LAN-WDM optical configuration, this module achieves a remarkable point-to-point transmission distance of up to 80 kilometers (80km) over standard duplex single-mode fiber (SMF)—all without the need for deploying costly and power-hungry coherent transport infrastructures.

Product Highlights
1. Extended 80km Long-Haul Reach
- Description: Outfitted with an exceptional optical power budget, this transceiver enables direct 100G data links up to 80km over standard OS2/G.652 single-mode fiber (SMF). It eliminates the necessity for intermediate mid-span amplification or external erbium-doped fiber amplifiers (EDFAs), drastically slashing regional network CapEx and OpEx for inter-campus and metro Data Center Interconnects (DCI).
2. Compliant 100GBASE-ZR4 Standard
- Description: Fully compliant with the IEEE 802.3ba 100GBASE-ZR4 specification. This strict adherence to industry standards ensures seamless, direct-detect optical interoperability with any other vendor-compliant standard ZR4 peer across your long-haul network fabric without requiring complex coherent transport infrastructure.
3. High-Sensitivity LAN-WDM + APD Receiver Architecture
- Description: Features an advanced optical design multiplexing 4 lanes across precise, low-dispersion LAN-WDM wavelengths grid-spaced around the 1310nm band (1295.56nm to 1309.14nm). Combined with a high-sensitivity APD (Avalanche Photodiode) receiver and NRZ modulation, it ensures maximum signal fidelity and superior link performance over extended fiber spans while conserving dark fiber assets.
4. Dual-Standard & Multi-Platform Versatility
- Description: Designed for flexible, mixed-network environments by supporting dual-rate transport at the physical layer, offering full compatibility with both standard 100GBASE-ZR4 Ethernet and telecom-grade OTN OTU4 line rates. It deploys seamlessly across Cisco Nexus switches, ASR routers, and ONS series OTN transport equipment.
5. Authentic Cisco Hardware with Green Hologram
- Description: Genuine Cisco hardware featuring the signature green holographic anti-counterfeiting sticker with fully traceable serial numbers. Delivers guaranteed zero-error, native plug-and-play operation across Cisco QSFP28 slots and maintains eligibility for official Cisco technical support.
