Post deleted. It was ambiguous which laser diode I was referring to.

That diode is only 150mw not 180

I also noticed that... at least, that's was the spec sheet says, 150mW. http://www.datasheets360.com/pdf/-5982051677738114279

Yep and I'm not one for over driving

It is 180mW. That is an old datasheet according to my supplier. See this one.

Thanks for clearing that up. I may be in for a handful of them in a few days.

DTR, Do you have a spec sheet for NUBM44? I would be interested in seeing the specified current and operating temperature range. The far field divergence straight out of the chip would be interesting to see as well to know what kind of fiber it can be coupled into. i realize that you demonstrated LI performance for a single device, but the official specs are created with longevity of the devices in mind.

Nope unless someone can find a datasheet for the NUBM44 array but till then unfortunately we will just have to go off the testing like we did with the 445's diodes when they first came out.

Attachment 47694

it appears they are being overdriven.

That is for NUBM05s ...... not NUBM44s *vigil
