I don't think that the light from LW SFPs is in the visible spectrum. SW is areound 750-850nm, which is visible (red), but LW is around 1300nm, which in the Infra-Red area. So you probably won't see a light with the naked eye.Stephen

My Avago longwave SFPs were delivered from HP and they've been working fine since the day I put them in - they replaced a pair of longwave 2Gbps SFPs that had been running for nearly a year. I see that your vendor part number ends in "-HP" too. Here's the details of one of mine:What version of firmware are you running? Are you licensed for long distance?
