Testing the connection of 2 Fiber Optic Switch

Im trying to deploy a point to point connection trough monomode fiber optic. Im using 2 x Switch with SFP Ports, LC Transceivers and an small Fiber cable, for testing.

Im using:
– 2 x Planet GSD-1002M Switch
– 2 x Planet MGB-TLX Transceivers
– 1 x LP-FO-6049B FO Jumper

1) Configure static IP’s in both switch (10.20.25.101 / 10.20.25.102)
2) Interconnected Both with an standard UTP/RJ45 cable, can access to both GUI’s from one of them.
3) Disconected RJ45, and interconnected with the transceivers & FO.
4) One of the Switches detects the FO link, and the LED’s turn on. IN GUI it shows as connected, and the transceivers are detected.
5) The other Switch, doesnt detect the FO link, the LED’s are off. In GUI, it recognizes the transceiver, but not the conection.
6) Changed SFP Ports, and transceivers, same results. One of the switchs detects the conection, the other dont.
