I agree, this is good.

At least when we buy optics from Cisco, we know we can use 
them on switches and routers without problems (although, for 
the foreseeable future, we'll probably still be buying OEM 
units due to the large cost differential).

Cheers,

Mark.

Hadn't seen this, but it is a good long term strategy - I'm glad that
someone in Cisco has finally decided to take the plunge.


Although, according to the transceiver compatibility matrix, there are
still a pile of products which don't explicitly support the GLC-*D
transceivers yet, even though the sfp-* and old-style glc-* SKUs are
scheduled to be phased out by July of this year.  Hope the backwards
compatibility is good, because transceivers can do odd things from time to
time.

[c-nsp] SFP consolidation GLC-*/SFP-* => GLC-* (Vlans on an ASR9000)

Cisco is consolidating the SFPs:
  


Basically GLC-* only (i.e. GLC-SX-MM + SFP-GE-S => GLC-SX-MMD).

SFP features on new Product IDs:
- Backward compatible
- Digital Optical Monitoring
- UDI compliant
- PbFree
- Extended temperature range of operation (-5°C to 85°C)

This almost looks like the specs from the SFP-*, no idea why the chose
the GLC-* SKU instead of the SFP-*.
