What this transceiver does

The Black Box LGC011A-R2 is a Gigabit Ethernet transceiver and media converter that links 1000Base-LX fibre at 1310nm to 1000Base-TX copper. It spans up to 6.21 Mile per link. The unit measures .8H x 1.8W x 3.4D inches and runs from an external universal AC supply or an optional rack-mountable PowerTray.

What to check before ordering

Confirm that your fibre infrastructure uses 1310nm single-mode cabling with LC connectors and that the link budget covers 6.21 Mile. Ensure the host equipment accepts a standalone media converter rather than a plug-in SFP module. Verify you have access to a mains outlet for the external power adapter or space for the optional PowerTray.

Who this suits and who should look elsewhere

This converter suits network teams extending Gigabit Ethernet between buildings or cabinets over existing single-mode fibre where a compact, externally powered device is preferred. It does not suit buyers who need a hot-pluggable SFP module for a switch port, those requiring multi-mode fibre support, or installations that demand Power over Ethernet for the copper port.

Questions about this item

Does the LGC011A-R2 ship with the external power adapter or must I buy it separately?

The unit includes a universal AC power supply; the optional rack-mountable PowerTray is sold separately.

When should I choose the 1000Base-LX port versus the 1000Base-TX port on this transceiver?

Use the 1000Base-LX port for 1310 nm fibre links up to 6.21 miles; use the 1000Base-TX port for copper Gigabit Ethernet connections.

What does the 6.21 mile distance rating mean for a live 1000Base-LX link?

It is the maximum reach on single-mode fibre at 1310 nm assuming standard loss budget and clean connectors.
