Ultra-Small Active Optical Module : LIGHTPASS™ Series
In data center equipment, it is common for outside the box, high-speed signal connectivity to be achieved using pluggable optical modules. However, with the increasing data rates, electrical losses also increase, reducing the effective distance of mid-board transmitters, requiring re-timers or the use of heavier gauge copper cable to reach the chassis port.
The LIGHTPASS™ Series makes it possible to shorten the copper trace length on the system board by placing the electrical-to-optical (E-to-O) conversion closer to the processor, reducing electrical transmission losses.
- LIGHTPASS™-EOB 100G :
By utilizing the small and ultra-thin features of the LIGHTPASS™-EOB 100G, electrical-to-optical and optical-to-electrical conversion in a position that is close to the processor is now available and can dramatically decrease the transfer loss which used to occur in the electrical wiring between the processor and the edge of the board.
- LIGHTPASS™-EOM 100G：
While the LIGHTPASS™-EOB 100G will have a built-in microprocessor in an ultra-thin package, LIGHTPASS™-EOM 100G omits the microprocessor to minimize the footprint.
