Product Features
Technical Overview
The CNFE2005M2 operates as a transparent media converter, supporting 10/100Base-TX Ethernet over both copper and fiber interfaces. It handles auto-negotiation and auto-MDI/MDIX on the RJ-45 ports, ensuring plug-and-play compatibility with standard network equipment.
On the fiber side, the ST duplex port uses 1310 nm multi-mode optics, providing a cost-effective solution for short to medium-distance fiber runs within buildings or campuses. The converter maintains full-duplex operation across all ports, with no configuration required for basic connectivity.
This section brings together practical product details such as Total Number of Ports, Network (RJ-45), Number of Network (RJ-45) Ports, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
Key Product Advantages
This media converter simplifies network upgrades by allowing existing copper infrastructure to connect to fiber backbones without replacing switches or routers. Its dual-channel design provides two independent conversion paths in a single unit, saving rack space and power compared to multiple single-port converters.
Distance Extension
Extend Ethernet segments beyond the 100-meter limit of copper cabling by converting to fiber optic signals capable of reaching 3 kilometers.
- Overcomes copper distance limitations
- Maintains signal integrity over longer runs
Media Flexibility
Connect copper-based devices to fiber optic networks, enabling mixed-media deployments that leverage the strengths of both cable types.
- Bridge between different network media
- Future-proof existing copper investments
Deployment / Use Cases
The CNFE2005M2 is ideal for extending network connections between buildings, connecting remote workstations to central switches, or integrating fiber backbones into predominantly copper networks. Its environmental tolerance and rack-mount capability make it suitable for controlled environments like server rooms, network closets, and industrial control panels.
Common applications include connecting edge switches to core network fiber, extending surveillance camera networks over longer distances, and integrating legacy copper devices into modern fiber-based infrastructure. The converter's transparent operation ensures compatibility with existing network equipment without requiring special drivers or configuration.
Building-to-Building Links
Connect network equipment between separate structures using fiber for electrical isolation and longer reach than copper permits.
Industrial Networking
Deploy in manufacturing or utility environments where fiber's immunity to electromagnetic interference provides more reliable connectivity than copper.
Physical Profile
The converter features a compact metal enclosure measuring 5.30" wide × 6.10" deep × 1.10" high (134.62 × 154.94 × 27.94 mm), designed for both desktop use and standard rack mounting. Its small footprint conserves valuable rack space in dense installations, while the sturdy construction ensures reliable operation in typical network environments.

FAQ
What types of connections does this media converter support?
The CNFE2005M2 supports two RJ-45 Ethernet ports for copper connections and one ST duplex port for fiber optic connections. The RJ-45 ports work with standard Category 5/5e/6 cables, while the ST port accepts multi-mode fiber with 1310 nm wavelength. This allows conversion between copper and fiber network segments.
What is the maximum distance supported over fiber?
This converter supports fiber connections up to 3 kilometers (approximately 1.86 miles) when using appropriate multi-mode fiber optic cable. This significantly extends the reach beyond the 100-meter limitation of standard copper Ethernet cabling, making it suitable for building-to-building links or long indoor runs.
What Ethernet speeds does this converter support?
The converter supports Fast Ethernet technology, specifically 10/100Base-TX, providing data transfer rates up to 100 Mbps. It handles auto-negotiation between 10 Mbps and 100 Mbps operation on the copper ports, ensuring compatibility with various network devices without manual configuration.
Can this converter be mounted in a rack?
Yes, the CNFE2005M2 features a rack-mountable form factor. Its compact dimensions (5.30" wide × 1.10" high) allow installation in standard 19-inch rack enclosures using appropriate mounting hardware. The unit can also be used on a desktop if rack mounting isn't required for your deployment.
What type of fiber optic cable is compatible?
This converter requires multi-mode fiber optic cable with ST connectors. It operates at 1310 nm wavelength, which is common for multi-mode applications. The ST duplex port ensures proper alignment for both transmit and receive fibers in a single connector interface.
What power source does the converter use?
The CNFE2005M2 is powered by an included AC adapter that converts to DC for the unit. This plug-in power supply provides reliable operation without requiring specialized power infrastructure. The converter doesn't support Power over Ethernet (PoE) but uses standard AC power input.
