I have two questions (trying to determine operational impact for me as an
end-user):
In a 4x10G module, if one laser or receiver breaks, what happens then?
Will the port shut down the same way it would with a 40G serial?
Also, future adhoc standard for 40G serial CWDM optics (ie someone
developing 40G serial CWDM-band colored optics the same way that has
happened on 1G and 10GE) speaks in favour of serial instead of 4x10G, or
am I mistaken?
