100Base-T to 100Base-FX Multi-Mode SC Fiber Converter - Compact

In this review the TRENDnet 100Base-T to 100Base-FX Multi-Mode SC Fiber Converter is evaluated for small business and campus backbone use. The bottom line: this standalone converter is best for anyone needing a simple, rugged link between copper Ethernet and multi-mode fiber up to 2 km, and the single biggest reason to buy it is straightforward, reliable fiber extension without the complexity or price of managed switches with GBICs. It installs quickly in a compact metal enclosure and delivers dependable 10/100 Mbps conversion for point-to-point runs.

Key Features

• Standalone Converter: Functions as a single-box converter so installers can add fiber endpoints without deploying a switch or chassis.
• Durable Metal Enclosure: The compact metal housing protects internal components and allows flexible placement in wiring closets or equipment rooms.
• Fiber Range: Supports multi-mode fiber networking up to 2 km (1.25 mi.), making it suitable for building-to-building backbone links at short campus distances.
• Auto-MDIX Ethernet Port: The 10/100 Mbps Ethernet port auto-detects and adjusts, simplifying copper connections to existing network gear.
• Clear Status LEDs: LED indicators report power and copper/fiber link and activity for quick diagnostics during installation.
• Manufacturer Protection: Includes a 3 year TRENDnet protection policy and access to English-speaking technical support during business hours.

Who It's For

The converter is aimed at small IT teams, contractors, and facilities managers who need a low-cost way to extend Ethernet over multi-mode fiber without adding managed switches. It is particularly useful for point-to-point runs between buildings, remote equipment closets, or where a rugged standalone device is preferred.

Those who need gigabit fiber links, long single-mode spans, or advanced management features should look elsewhere; this unit is focused on reliable 10/100 Mbps conversion rather than switch functionality or SFP/GBIC flexibility.

Pros & Cons

Pros

• Reliable conversion between copper and multi-mode SC fiber for up to 2 km, meeting common short backbone needs.
• Compact, metal build with included power adapter that simplifies standalone installations and adds durability.
• Easy to set up with LEDs and Auto-MDIX on the Ethernet port, reducing configuration time for technicians.
• Backed by a 3 year manufacturer protection plan and reachable English-speaking technical support.

Cons

• Limited to 10/100 Mbps speeds and multi-mode SC fiber; not appropriate for sites requiring gigabit or single-mode long-haul fiber.
