Hi all,

I am trying to extend my ethernet LAN by 260m using two TP-Link MC210CS gigabit media converters and the required fibre optic cables.

On one end, the MC210CS has ALL 4 LED lights on (FX Link, PWR, TP Link, and the TP RX is flashing occasionally).

On the other end, the MC210CS has the FX Link LED OFF and the other 3 LED lights are on (with the TP RX flashing occasionally).

Other details:
- the RJ45 cables are running 1GB (1000BASE-T) ethernet at each end.
- the fibre cables are cross connected: TX at start with RX at the other end; RX at the start with TX at the other end
- I have swapped the fibre pair (blue/brown swapped with orange/green) and get the same result (FX Link is off at one end)
- Both media converters are in "Force" mode
- Fibre strands are all single-mode 9/125um

Any idea as to what the problem might be ?
