Product Discontinuation


Will the Trilithic product line and brand change?

Many Trilithic products will be rebranded as VIAVI over the next year or so, and in the case where duplication exists select VIAVI and Trilithic products will be discontinued. Formal discontinuation notices will be sent for impacted products enabling last time buys.  Consult your Sales Rep if you have questions about a specific product.
