I have an LX transceiver plugged into an GBIC. I enable this port, but there is no laser beam. I checked this issue on a SX transceiver and I found laser beam. I do not know it is a normal situation on my LX transceiver or not.
I failed to ask, how are you determining you have laser beam? Are you doing a simple loopback using a short patchcord from transmitter to receiver on the GBIC? Or, are you testing with an optical power meter?
The SX GBIC requires multimode fiber and the LX is used on singlemode fiber.
