Media converter for copper-to-fiber migration

The Intellinet Network Solutions 506519 is a Fast Ethernet media converter built for network managers who need to connect copper-based Ethernet segments to multi-mode fiber links. It serves installers extending campus or building-to-building runs without adding routers. It is not for buyers who need Gigabit or 10 Gigabit throughput or single-mode fiber reach.

Dual-port 100 Mbps link with ST duplex fiber

The converter provides one 10/100Base-TX RJ45 port with Auto MDI/MDI-X and auto-negotiation alongside one 100Base-FX ST duplex port operating at 1310 nm wavelength. Multi-mode fiber at 62.5/125 or 50/125 µm supports distances up to 1.24 mi, while the copper port reaches 100 m or 300 ft. Flow control is supported on both interfaces.

Compact desktop unit with external power adapter

The device measures 1.0' Height x 2.8' Width x 4.2' Depth and ships with an external power adapter, so it draws power from a wall outlet rather than a switch chassis. Status LEDs indicate power and Link/TX activity for each port, giving immediate visual confirmation of link health. No fan is present, so operation is silent in normal office or wiring-closet environments.

Questions about this item

What does the 100 Mbps headline rate mean for actual network traffic?

The converter runs at 100 Mbps on both copper and fibre ports, so every frame passes through at wire-speed Fast Ethernet without buffering delays.

How does the ST duplex fibre interface limit the link?

The ST duplex port uses 1310 nm multi-mode optics and supports up to 1.24 mi over 62.5/125 µm or 50/125 µm cable, capping reach at that distance.

What physical space and mounting does the unit need?

It measures 1.0 in high by 2.8 in wide by 4.2 in deep and ships with an external power adapter for desktop or shelf placement.
