[j-nsp] ACX5048 - 40 gbps ER 40 km optic

[Chuck Anderson]

Insert a 3dB or 7dB attenuator pad for lab testing.  In a pinch (no pun intended) you can take a fiber jumper and bend it tightly into a loop (like 1/4" diameter) to attenuate the signal, but I would use a disposable jumper for that.  Use a twist tie or similar to hold it in the tight loop.  Monitor the receive power level while adjusting the tightness of the loop until it is lower than -5 dBm but higher than -20 dBm.

So that’s probably why you see no light right now…. Lemme get back into the office Monday and we will go from there… yeah, as I mentioned I’m working with my Juniper account SE on this, so he may update support matrix if he discovers they are good…. I dunno.
