Overview
FMC-100-GE-SFP: Gigabit Ethernet Media Converter | 1 RJ45 to 1 SFP Slot | Copper to Fiber Conversion
The FMC-100-GE-SFP from BENCHU GROUP is a high-performance Gigabit Ethernet media converter designed to seamlessly bridge copper and fiber optic networks. Equipped with one 10/100/1000Base-T RJ45 port and one 1.25G SFP slot, this unmanaged converter enables reliable data transmission over extended distances, overcoming the 100-meter limitation of traditional copper cabling while providing electromagnetic interference (EMI) immunity inherent to fiber optics.
The FMC-100-GE-SFP provides a cost-effective and future-proof solution for organizations transitioning from copper-based to fiber optic infrastructure. By preserving all network protocols and maintaining bit-transparent conversion, it ensures seamless integration with existing switches, routers, and network interface cards from all major manufacturers.
Features
Extended Reach: From 100m Copper to 120km Fiber
The FMC-100-GE-SFP addresses the fundamental limitation of copper Ethernet—the 100-meter distance constraint—by converting 10/100/1000Base-T signals to fiber optic transmission. Depending on the SFP module selected, this media converter enables: Multi-mode fiber (SX): Up to 550 meters at 850nm, Single-mode fiber (LX): Up to 10 kilometers at 1310nm, Extended reach (EX/ZX/EZX): Up to 120 kilometers at 1550nm, This capability allows businesses to connect geographically dispersed facilities, campus buildings, remote surveillance sites, and metropolitan area networks without signal degradation, electromagnetic interference, or increased latency—maintaining full Gigabit throughput end-to-end.
Universal SFP Compatibility for Maximum Flexibility
Unlike proprietary media converters that lock you into specific vendors, the FMC-100-GE-SFP is designed for universal SFP compatibility per SFP MSA (INF-8074i) standards. It accepts standard SFP modules from Cisco, Juniper, Huawei, Finisar, TP-Link, and other major manufacturers.
True Plug-and-Play Deployment
The FMC-100-GE-SFP is engineered for zero-touch installation: Auto-negotiation: Automatically detects and configures speed (10/100/1000Mbps) and duplex mode, Auto-MDI/MDIX: Eliminates crossover cables—use standard straight-through cables, No software configuration: No IP addresses, no VLAN settings, no management overhead
This plug-and-play simplicity delivers tangible operational benefits: Deploy in minutes: Ideal for emergency installations and remote sites without IT staff, Reduce training costs: Any technician can install without specialized training, Minimize errors: No misconfiguration risks associated with managed devices, Scale efficiently: Large rollouts become practical and cost-effective
6KV Lightning Protection for Industrial Reliability
The FMC-100-GE-SFP features built-in surge protection rated at 6KV on both power and Ethernet ports, complying with IEC 61000-4-5 surge immunity standards. This protection is critical for: Outdoor installations: CCTV cameras, perimeter security, cell towers, Industrial environments: Factories, power plants, oil and gas facilities, Utility infrastructure: Smart grid monitoring, traffic control systems, Rural deployments: Long-distance runs susceptible to electrical interference
Full Wire-Speed Performance with Zero Packet Loss
The FMC-100-GE-SFP operates as a layer 1 media converter, providing bit-transparent transmission with: Line-rate forwarding: 1Gbps in full-duplex mode, IEEE 802.3x flow control: Prevents packet loss during congestion, Low latency: < 1.6 microseconds per conversion, Jitter tolerance: Maintains signal integrity for time-sensitive applications
