I have a 15' optical handoff run from our ISP Flashwave to a 3845. We need an SFP capable of handling 1310nm single-mode transmission, but the GLC-EX-SMD has far more power than we'd need. I'm thinking a lower-powered SFP that still meets the transmission criteria would be less expensive and wouldn't require a 5dB attenuator.
I can't find another suitable option, can anyone suggest something different? And if not, perhaps a link to optical attenuators that would work well with the GLC-EX-SMD?
Thanks in advance!
You're welcome and thanks for the rating.
Actually Cisco refers to it both ways (1300 and 1310). Please see Table 4 in this document (and contrast with Table 1).
The GLC-LH-SM/D is very commonly used in just this application - metro Ethernet and service provider type of handoffs.
