ReConfigurables
The basic concept of replacing fixed interfaces with pluggable transceivers like GBIC, SFP, XFP and SFP+ has wide range of advantages:
Beside the basic strengths most cost optimized transceivers have an often overseen hardware weakness:
Limited ReConfigurability
The optimization of the manufacturing process as a result of mass production often results in limitations of the interoperability. Those units are often assembled with static modules which later restrict the reprogramming ability. That results in limited reprogramability or the need of complex reinitialization methods.
Whereas flexOptix transceivers contain an integrated micro controller which allows specified and approved configuration changes.
The simple reconfigurability of your transceivers provides the highest possible long term reusability. Regard that before you book your next order.
