Re: 100GBASE-SR10 interwork with 10GBASE-SR

[Chad Lamb <chad () xkl com>]

Steven,

In general, there isn't much to worry about optically when interfacing 
100GBASE-SR10 and 10GBASE-SR.  If you are using CFP transceivers or CXP 
transceivers for the 100GBASE-SR10, your mileage may vary.  For example, 
the Avago CXP AFBR-83PDZ has a transmit power range of -7.6dBm to 2.4dBm 
per lane.  The Avago XFP AFBR-720XPDZ has an overload value of 1dBm on 
the receiver.  We've observed errors when operating a device above the 
overload value. So attenuation is needed.  There are "interoperable" 
devices from various vendors, making sure the optical interfaces do not 
need attenuation.  I can provide more details offline, let me know what 
you are thinking about using.
