Hi Nick,

That's the beauty of the implied warranty of fitness for particular
purpose. The seller doesn't have to give any specs at all. He just has to
lead you to believe that the product is suitable for some purpose, such as
providing gige to customers. Sometimes, even the fact that the seller was
aware of the buyer's intended use and failed to warn him is enough. If it
then proves unsuitable for that purpose for any reason, the seller is on
the hook.

IANAL and I think Baldur should consult one before taking any action, but
unless Baldur's use obviously and significantly differed from Zhone's
advertised intended use Baldur probably has a case.
