US Conec, a developer of high-density optical interconnects, has launched its next-generation PRIZM LightTurn mechanical-optical interface, optimized for 25+ Gbps VCSEL-based links.

Used in embedded module applications, the MOI is designed for efficient coupling between on-board active components and US Conec’s PRIZM LightTurn connector, which utilizes expanded beam-lensed ferrule technology.

US Conec last week presented a joint paper at the Photonics West Exhibition in San Francisco on the theoretical and empirical results for its new PRIZM LightTurn MOI 25+ Gbps.

Improvements are necessary in the optical links between active optical devices. With the evolution of 10 Gbps to 25 Gbps and beyond, the critical components of VCSELs and photo-diodes must be redesigned to enable more stringent part and assembly tolerances for maintaining system performance. For example, in order to achieve higher response speeds, the PD must be reduced, necessitating a dramatically reduced available aperture.

“Understanding that coupling optimisation between the reduced aperture optics and fiber optic connectors is increasingly critical to the performance of the systems, US Conec redevelops its PRIZM LightTurn MOI into a next generation design for efficient coupling of faster active VCSEL/PD arrays to fiber optic connectors,” said Sharon Lutz, US Conec Ferrules Product Manager.

“The PRIZM LightTurn MOI 25+ Gbps accommodates a wider variety of transceiver architectures by taking into account the chip driver and wire-bond clearance requirements while optimizing the optical lens design to maximize coupling performance for both Tx and Rx.”
