exact item shown, three AT-MC1004 gigabit ethernet converters, includes OEM power supply.  photos show you LEDs and the Lser on hte TX port

from the manual (located here: https://docs.rs-online.com/80cc/A700000008933736.pdf  )which is a little more recent than this device so it only as the XL and LH, and not the one with only a single pair of optical connectors and a copper ethernet.

The AT-MC104XL and AT-MC104LH media converters feature two 100Base-FX fiber optic ports with either dual SC or dual ST connectors. One port uses multi-mode fiber optic cabling and has a maximum distance of 2 kilometers (1.2 miles). The second port uses single-mode fiber optic cabling and has a maximum distance of 15 kilometers (9.3 miles) to 40 kilometers (24.8 miles), depending on the model. 
 These media converters operate at 100 Mbps and feature half- and full duplex operation

I normally ship within 24 hours of your order, but the post office does not always initiate tracking when I put the packages in the drop off box.
