CTF-Quadrax technology is the embedding of a transmit or recieve optical sub-assembly into a Quadrax contact. Quadrax is a size 8 keyed contact with 4 or 8 pins used in high speed copper signaling applications. The embedding of a TOSA/TOSA into this component provides the ability to utilize a Quadrax connector for media converter applications. ROSA/TOSA components are available in all major fiber protocols to include 850nm multi-mode, 1300nm multi-mode (typically used in 100-Base-FX applications), 1310nm single mode, and other varieties for support of a plethora of interfaces customers are utilizing in platforms and systems.
