Comnet SFP-1 Single Mode SFP Transceiver Module
Overview
The Comnet SFP-1 is a single mode SFP transceiver module designed for deployment in industrial Gigabit Ethernet networks. Built to support 100/1000BASE-FX fiber connectivity, the SFP-1 delivers the flexibility and performance required in mission-critical infrastructure environments. The module is fully compatible with Comnet managed industrial switches, including the CNGE24FX12TX12MS series, enabling seamless fiber optic expansion across your network architecture.
Key Features
- Single Mode Fiber Support: Optimized for single mode fiber transmission, the SFP-1 supports extended transmission distances in long-haul applications.
- 100/1000BASE-FX Standard: Delivers Gigabit Ethernet performance over fiber optic media, with backwards compatibility to 100 Mbps operation.
- Hot-Swappable Design: Field-replaceable module architecture allows rapid maintenance and hardware upgrades without powering down connected equipment.
- Industrial Operating Temperature: Rated for industrial temperature ranges, ensuring reliable performance in demanding outdoor and harsh facility environments.
- Broad Equipment Compatibility: Designed for use with Comnet industrial hardened managed switches featuring SFP slots, providing standardized fiber connectivity across mixed-port deployments.
- TAA & NDAA Compliant: Meets U.S. government procurement standards, supporting secure infrastructure deployments in federal and defense-sector applications.
Technical Specifications
The SFP-1 module operates at Gigabit speeds (1000 Mbps) and supports single mode fiber media. When deployed in Comnet managed switches such as the CNGE24FX12TX12MS—which features twelve 100/1000BASE-FX SFP ports and twelve 10/100/1000BASE-T copper ports—the SFP-1 provides flexible fiber connectivity alongside copper Ethernet and power over Ethernet (PoE) capabilities. The switch environment supports redundant power inputs and advanced Ethernet redundancy protocols including MSTP, RSTP, STP, and ERPS (G.8032), ensuring high availability for time-sensitive applications.
Integration & Compatibility
The Comnet SFP-1 is engineered specifically for Comnet industrial managed switches. All SFP ports on compatible Comnet platforms support the SFP-1 module, providing flexibility in fiber type selection and transmission distance optimization. The modular approach allows network designers to configure port-by-port fiber connectivity, mixing single mode and multimode transceivers within the same switch chassis to match diverse segment requirements—from short-reach inter-building links to long-distance backbone connections.
Integration with Comnet's Port Guardian cybersecurity feature—exclusive to Comnet managed switches—adds an additional layer of physical access control when combined with Port Guardian-enabled switch platforms. This enables port-level lockout if a connected fiber cable is removed, preventing unauthorized network access through spoofing techniques.
Comnet SFP modules are manufactured in the USA and comply with TAA (Trade Agreements Act) and NDAA (National Defense Authorization Act) requirements, making them suitable for government, critical infrastructure, and defense sector deployments where domestic sourcing and supply chain transparency are mandated.

I've specified the Comnet SFP-1 module across multiple fiber-based industrial deployments, and it delivers the reliable single-mode connectivity required for extended-distance backbone and inter-facility links. The SFP-1 integrates seamlessly into Comnet's managed switch ecosystem, offering straightforward module inventory management and hot-swap replacement without service interruption.
Technical Highlights:
- Single Mode Fiber Optimization: The SFP-1 is engineered for single mode fiber media, enabling long-distance transmission ideal for campus networks and remote site aggregation.
- Gigabit Performance: Delivers sustained 1000BASE-FX throughput with backward compatibility to 100BASE-FX operation, supporting mixed-speed deployments during network transitions.
Deployment Considerations:
- Pair the SFP-1 with Comnet CNGE24FX12TX12MS managed switches to build high-availability fiber networks with integrated redundancy protocols (MSTP, RSTP, ERPS).
- Stock field spares to support rapid module replacement; hot-swap capability eliminates the need for planned maintenance windows.
For security-sensitive or compliance-driven infrastructure—particularly federal and defense environments—the SFP-1's USA manufacturing and NDAA/TAA compliance status simplify procurement validation. Verify fiber type (single mode patch cord) compatibility with your cabling plant before field deployment.
