Product Features
Technical Overview
Technically, the CNFE2004S1A operates as a transparent media converter, supporting Fast Ethernet (10/100Base-TX) over both twisted pair and optical fiber. The two RJ-45 ports handle standard Ethernet connections, while the SC simplex port interfaces with single-mode fiber cables.
It uses 1310 nm and 1550 nm wavelengths for fiber transmission, which are common for long-distance single-mode applications. The converter is powered by an included AC adapter, ensuring stable operation without PoE dependency.
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 extends network reach efficiently by converting copper Ethernet to fiber optic links, reducing signal degradation over long runs. Its dual-channel design allows two separate network segments to be converted simultaneously, saving space and cost compared to single-channel units.
Long-Distance Reliability
Supports up to 20 km on single-mode fiber, ideal for connecting remote buildings or industrial sites without signal loss.
- 1310/1550 nm wavelengths
- Single-mode fiber compatibility
Flexible Installation
Mountable and rack-mountable form factor with compact dimensions fits standard racks or wall mounts for versatile deployment.
- 1.10" height profile
- Includes power supply
Deployment / Use Cases
Deploy the CNFE2004S1A in scenarios where Ethernet needs to be extended beyond the 100-meter limit of copper cabling. It is commonly used in campus networks, industrial automation, security camera systems, and telecommunications infrastructure.
Typical use cases include connecting remote switches or devices over fiber, integrating fiber backbones into existing copper networks, and providing noise immunity in electrically noisy environments. Its two channels allow separate network segments, such as data and voice VLANs, to be converted independently.
Physical Profile
The converter has a compact design measuring 5.30 inches wide, 6.10 inches deep, and 1.10 inches high, making it suitable for dense rack installations. Its mountable and rack-mountable form factor includes mounting hardware for secure placement in network closets or industrial enclosures.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.10" (27.94 mm), 5.30" (134.62 mm), 6.10" (154.94 mm). This helps confirm rack, shelf, desk, or cabinet fit before installation.
