Comnet Small Size 100Mbps Media Converter (B) ST Connector AC/DC Power mm 1 fiber - CNFE1002MAC1B-M

Comnet CNFE1002MAC1B-M 10/100 Mbps Ethernet-to-Fiber Media Converter

Overview

The CNFE1002MAC1B-M is a single-channel Ethernet media converter that bridges copper twisted-pair (10/100 BASE-T) to single-fiber 100 BASE-FX optical — solving the core problem of long-distance surveillance transport where electrical Ethernet runs into noise, distance, or electrical isolation constraints. This compact unit (3.3 × 2.5 × 1.1 inches) accepts standard RJ-45 input and converts to ST optical connectors, supporting both multimode fiber (up to 3 km) and singlemode fiber (up to 20 km). The included DC power supply handles 90–264 VAC input, and the unit operates across -40°C to +75°C, making it suitable for outdoor backbone runs, rooftop-to-shelter fiber links, or electrically noisy industrial environments. Auto-negotiation on the electrical side means it works at either 10 or 100 Mbps without manual configuration.

Compatibility

The CNFE1002MAC1B-M integrates into any surveillance system that requires fiber extension: IP camera networks (Axis, Hikvision, Dahua, Uniview, or any ONVIF-compliant device), network video recorders, and managed switches. It pairs with standard multimode or singlemode fiber cable runs and works with backbone architectures where copper drops from POE switches to remote cameras, then transition to fiber for long distances. The unit is transparent to data encoding — it does not inspect or modify traffic, so it supports all standard VMS protocols and camera management systems without additional configuration.

Installation Notes

ST connectors require firm seating to ensure loss under 0.5 dB per joint. Voltage transient protection is integrated on all power and signal lines — no separate surge suppression is required, but ensure AC input voltage remains within 90–264 VAC to avoid damaging the internal power stage. The unit is not hot-swappable in wall-mount configuration; power down before inserting or removing. Relative humidity tolerance is 0–95% non-condensing, so in high-condensation environments (unheated sheds, outdoor cabinets without ventilation), allow 15–30 minutes warm-up time before optical connection to prevent connector fogging. Power draw is only 3 watts, so no dedicated circuit breaker is required. Multimode fiber (62.5/125 μm or 50/125 μm) yields 3 km maximum range; singlemode (9/125 μm) extends to 20 km, making singlemode the choice for campus-wide or regional fiber backbone runs.
