Media Converter for Gigabit Fibre Links

This Transition Networks media converter bridges a copper RJ-45 port and an LC multi-mode fibre port at 1000 Mbit/s. It operates at 850 nm wavelength over distances up to 0.55 km. The plug-and-play design requires no configuration and passes traffic at line speed for low-latency connections.

Suited for Short-Range Multi-Mode Deployments

Installers extending a Gigabit Ethernet segment across a building or campus using existing multi-mode fibre will find this unit fits the requirement. Buyers needing single-mode reach beyond 0.55 km or a different connector type should select an alternative device.

850 nm Multi-Mode Reach of 0.55 km

The fixed 850 nm multi-mode interface limits the link to 0.55 km, so the fibre run must stay within that distance. Verify that the existing cabling plant matches this wavelength and reach before purchase.

Questions about this item

What type of RJ-45 network cable do I need to connect the 1000Base-T side?

Use a standard Cat5e or better twisted-pair cable; the RJ-45 port negotiates 1000 Mbit/s full-duplex automatically.

Can I link this converter to an existing 100 Mbit/s switch on the copper side?

The 1000Base-T port is fixed at Gigabit speed and will not negotiate down to 100 Mbit/s, so the link will not come up.

How do I confirm the fiber link is operating at the rated 0.55 km distance?

The LC port LEDs show link and activity; a steady link light with traffic blinking indicates the 850 nm multi-mode path is working at line speed.
