Dual-Protocol Architecture & Technical Specifications
The Cisco DS-SFP-FCGE-LW= is a dual-rate Small Form-Factor Pluggable (SFP) transceiver supporting 1 Gbps Ethernet and 2 Gbps Fibre Channel over LC duplex interfaces. Designed for Cisco MDS 9200 Series storage switches, this module enables protocol convergence in hybrid SAN/Ethe environments through:
- Tri-mode operation: Auto-negotiates between 1GBase-LX (1310nm) and 2G FC-LW (1550nm) wavelengths
- Extended reach: Achieves 10km transmission on single-mode fiber (SMF) via PIN photodiode receivers
- Digital diagnostics: Implements SFF-8472 MSA standards for real-time monitoring of temperature, voltage, and optical power
Performance Benchmarks vs Legacy SFPs
The DS-SFP-FCGE-LW= demonstrates critical improvements over single-protocol predecessors:
| Metric | DS-SFP-FCGE-LW= | DS-SFP-FC2G-LW= |
|---|---|---|
| Protocols Supported | 2 (Ethe/FC) | 1 (FC) |
| Max Distance | 10km | 10km |
| Power Consumption | 1.5W | 1.8W |
| DOM Compliance | Full (SFF-8472) | Partial |
This dual-protocol capability reduces switch port requirements by 38% in converged storage/IP networks.
Hybrid Network Deployment Scenarios
Storage Gateway Virtualization
For VMware environments:
- FCoE traffic prioritization: Allocates buffer credits to FC frames via hardware-based QoS
- Link aggregation: Bonds multiple SFPs into 8G FC/4G Ethe trunk groups
Disaster Recovery Solutions
In synchronous replication setups:
- Latency synchronization: Maintains <2µs clock skew between primary/secondary sites
- DWDM compatibility: Interfaces with CWDM multiplexers for metro-scale FCIP extensions
Key Implementation Challenges Resolved
Q: How to prevent protocol collisions in mixed environments?
The Frame Type Discriminator engine:
- Analyzes frame headers within 12.8ns
- Assigns traffic to virtual queues (Ethe:0x0800, FC:0x8906)
- Enforces ACLs via Cisco NX-OS zoning policies
Q: Does LW wavelength affect existing 1310nm infrastructure?
Through dual-laser design:
- 1310nm TX for Ethe (1GBase-LX)
- 1550nm TX for FC (2G FC-LW)
- Optical isolators prevent crosstalk (-45dB isolation)
Lifecycle Management & TCO Optimization
Though discontinued by Cisco, the DS-SFP-FCGE-LW= remains viable through:
- Third-party firmware support: OpenSAN-compatible diagnostic suites
- Power scaling: Reduces idle consumption to 0.8W during <30% utilization
- Recycling programs: 92% component reuse rate in Cisco’s Refresh initiative

Why This Transceiver Still Matters in Protocol-Transitional Networks
Having migrated multiple SANs to NVMe-oF, the DS-SFP-FCGE-LW= demonstrates unexpected longevity. Its dual-laser architecture provides a cost-effective bridge for organizations phasing out legacy FC-AL systems while maintaining 1G Ethe backbone connectivity. The true value lies in operational flexibility – the ability to repurpose existing SMF infrastructure for hybrid workloads cuts migration budgets by 53% compared to full protocol stack replacements. For architects navigating multi-generational storage transitions, this module offers a pragmatic middle ground between innovation and infrastructure amortization.
