Key Product Advantages
The CNFE1S1B/2 simplifies network expansion by converting copper Ethernet to fiber optic signals, preserving bandwidth integrity over longer distances where traditional copper cabling would degrade. Its dedicated ST fiber port ensures compatibility with standard single-mode patch cables, while the RJ-45 port connects seamlessly to existing switches, routers, or endpoints.
Extended Reach
Supports fiber optic links up to 20 kilometers, eliminating distance constraints common with copper-based Ethernet.
- Ideal for connecting remote buildings or equipment
- Reduces signal loss and interference risks
Simplified Integration
The internal design and power supply requirement allow for straightforward deployment in network closets, racks, or controlled environments.
- Minimal installation effort
- No external management port needed
Deployment / Use Cases
This media converter is particularly effective in scenarios where network segments must traverse long distances or harsh electrical environments. It enables organizations to leverage existing copper infrastructure while extending connectivity via fiber optic backbones.
Common applications include connecting surveillance cameras over extended campus areas, linking network switches between separate buildings, or integrating industrial control systems where fiber optic immunity to EMI is critical. The converter also supports network upgrades by allowing gradual migration to fiber without replacing entire copper networks.
Surveillance & Security
Extend IP camera feeds over single-mode fiber to central monitoring stations, maintaining video quality across large facilities.
Industrial Networking
Connect PLCs, sensors, or control systems in manufacturing plants where fiber optic cabling resists electrical noise and ground loops.
Physical Profile
The converter features a compact internal form factor with dimensions of 1.10" (27.94 mm) in height, 1.90" (48.26 mm) in width, and 1.90" (48.26 mm) in depth. This small footprint facilitates installation in space-constrained environments such as network racks, enclosures, or equipment panels. The design prioritizes reliability and ease of integration, with no external adjustments or mounting hardware required beyond standard power connection.

FAQ
What does this media converter do?
The ComNet CNFE1S1B/2 converts Fast Ethernet signals between a copper RJ-45 port and a single-mode ST fiber optic port. It allows network traffic to travel over fiber optic cabling for distances up to 20 kilometers, extending network reach beyond typical copper limitations while maintaining 100 Mbps data rates.
What types of fiber optic cable does it support?
This converter supports single-mode fiber optic cables with ST connectors. It is compatible with wavelengths of 1310 nm and 1550 nm, which are standard for long-distance single-mode fiber applications in enterprise and industrial networks.
What is the maximum distance this converter can achieve?
The maximum supported distance is 20 kilometers (approximately 12.43 miles) over single-mode fiber. This makes it suitable for connecting network segments across campuses, between buildings, or in large facilities where copper Ethernet would be impractical due to signal degradation.
What network speeds does it support?
It supports Fast Ethernet speeds, specifically 10/100Base-TX on the RJ-45 copper side and 100Base-FX on the fiber side. This provides data transfer rates up to 100 Mbps, adequate for many surveillance, industrial control, and general networking applications.
How is this converter powered?
The converter requires an external power supply for operation. It does not support Power over Ethernet (PoE) or other alternative power methods, so a dedicated power source must be provided during installation in network racks or enclosures.
What is the form factor and installation process?
This is an internal form-factor device with compact dimensions of 1.10" H x 1.90" W x 1.90" D. Installation involves connecting the RJ-45 and ST fiber ports to respective cables, providing power via the external supply, and integrating it into a rack or enclosure. No management port or configuration is needed, making setup straightforward.
