The LightVISION™ with emQSFP+™ acts like a QSFP+ but offers reduced dimensions and power consumption, industrial temperature range, multiple board mounting options, and board mount and edge mount capability. This new optical module will outclass QSFP+ on multiple front and it is backed by Reflex Photonics proven reliability and rugged design. This new device is perfectly suited for 40GigE high-speed camera and demanding machine vision applications.
Description of the application
40GigE camera can generate of to 40 Gbps of data that needs to be transferred from the sensor to servers or computers across a fast and reliable link.
It is well known in the high-bandwidth connectivity world that signal integrity tends to degrade at baud rate higher than 10 Gbps over traditional copper links. At these rates, an optical link is the only viable solution to transfer the information generated by these high-bandwidth devices.
This is why 40GigE camera integrator are now offering cameras that integrate optical module capable of >40 Gbps electro-optical conversion. For that purpose, up to now, camera designers were considering QSFP+ devices.
Reflex Photonics is proud to offer an innovative solution that integrates the capabilities of QSFP+, but in a format, that occupies 7 times less space, offers multiple board mounting option, and consumes less power. The LightVISION is now giving camera designers the ability to envision more compact and more reliable product that can be deployed in harsh environments.

LightVISION with LightSNAP interface
The LightVISION is a screw-in, robust, industrial and RoHS optical module with LightSNAP interface. LightSNAP adds a standard MPO pluggable optical interface to the LightVISION optical module. This combination allows a standard MPO cable to be plugged in the camera housing and on a frame grabber card.
This approach offers a standard MPO cable connection with a robust, board mounted optical engine providing small size (footprint) and convenient optical cabling at the same time. In addition, the MPO connector is covered with an outside cover boot addressing the issue of water and dust contamination.
LightVISION is offered as a 2, 4, 6, 8, 10, 12-lane transmitter, 2, 4, 6, 8, 10, 12-lane receiver or a 4+4-lane transceiver.
