1. Part Number & Naming Definition
Official Full Name
Cisco Multirate 10GBASE-ZW SFP+ Single-Mode Optical Transceiver Module with Digital Optical Monitoring Support
SKU:SFP-10G-ZW
Naming Breakdown
-
SFP+: Enhanced Small Form-Factor Pluggable Plus hot-swappable transceiver form factor
-
10G: 10 Gigabit serial data rate class
-
ZW: WAN PHY variant of Cisco proprietary 10G long-haul transmission standard; compatible with SONET/SDH OTU2 framing
Core Product Positioning
The Cisco SFP-10G-ZW is a hot‑swappable commercial-grade multirate SFP+ transceiver. It implements the WAN PHY specification for 10G transmission, supporting 10GBASE-ZW, 10GBASE-ZR and OTU2/OTU2e line rates over standard single-mode fiber. Optimized for service provider transport networks, carrier WAN backbones and long-distance enterprise interconnections requiring seamless interoperability with SONET/SDH transport gear. Built-in DOM/DDM enables continuous real-time monitoring of internal optical operating parameters. This module supports Fibre Channel over Ethernet (FCoE) for converged storage and data networking.
Important Note: 10GBASE-ZR/ZW isnot defined within IEEE 802.3ae, it follows Cisco proprietary optical specifications for extended long-haul reach.
2. Hardware & Software Compatibility
Supported Host Platforms
Cisco Catalyst 3650, 3850, 4500-X, 6500, 6800, 9200, 9300 Series; Nexus 2000, 3000, 5000, 9000 Series Switches; ASR 1000, ASR 900 Series Routers; UCS Fabric Interconnects; MDS 9000 Storage Switches and Firepower appliances equipped with SFP+ ports.
Supported IOS / IOS XE / NX-OS Versions
All mainstream Cisco operating system releases supporting SFP+ MSA specification and SFF‑8472 DOM diagnostic functions.
Supported Fiber Type
Single‑Mode Fiber (SMF) G.652 (9/125μm) only; incompatible with multimode fiber.
Unsupported Platforms
