Black Box LGC211A-R2 KVM Switch Media Converter 10/100/1000BASE-TX to 1000BASE-SX 850 nm 550 m

Media Converter for Gigabit Ethernet

This media converter bridges 10/100/1000BASE-TX copper networks to 1000BASE-SX fibre using an 850 nm wavelength. It supports auto-negotiation per IEEE 802.3 and 802.3u standards. The unit provides a single RJ-45 port and a duplex SC fibre interface. Maximum transmission distance reaches 550 m over multi-mode fibre.

Suits Installers Extending Copper Links Over Fibre

Network engineers extending Gigabit Ethernet beyond copper limits will find the 550 m reach useful for building-to-building or floor-to-floor runs. The converter includes broadcast storm control, flow control, and CRC error checking for link reliability. It is not for installers needing single-mode fibre distances or 10 Gbps fibre throughput. Buyers requiring multiple fibre ports or managed switching features should look elsewhere.

Verify Power and Mounting Before Ordering

The device ships with a 5 VDC power adapter that includes US, EU, UK, and AU clips. Confirm the adapter suits your local mains supply and that a nearby outlet is available. The chassis is standalone and rack-mountable; check your rack space and mounting hardware if you plan to install it in a cabinet. Ensure your fibre patch cables use duplex SC connectors compatible with the converter's ports.
