What are Universal Transceivers?

Universal Transceivers have been designed to reliably convert electrical signals to high speed optical data communication.
No matter, which data rate, form factor or host system – they just work.

Universal Transceivers and FLEXBOX

And where Universal Transceivers are the mandatory base for optical networks, the unique FLEXBOX series show its full complementary potential.
It’s a toolset, tailored for professional network builders.
Most MSA standardized form factors like SFP+, QSPF+, QSFP28 do not guarantee flawless operations across various host systems.  
The root cause is the electrical interface of the transceiver, as it typically cannot be adjusted to the varying hand-shake requirements of different switches or routers.
FLEXOPTIX' Universal Transceivers overcome this obstacle and can be used in various host systems.
