End-of-life status

The EX-SFP-1GE-LX is end-of-sale

Juniper has declared the EX-SFP-1GE-LX end-of-sale, so it is no longer manufactured new. TFI supplies it professionally refurbished and tested.

Why refurbished still makes sense: a refurbished EX-SFP-1GE-LX delivers the same proven performance at a fraction of the new-equipment cost, backed by a TFI warranty and SLA. It is the practical choice for spares, expansion of an existing deployment, or extending the life of a network you are not ready to replace. Talk to us about a successor model if you are planning a refresh.
